Yomit.ai is a Japanese dictionary and study toolkit that runs entirely in your browser. Every tool is reached from the feature menu in the header at the top of the screen:
The dictionary, Learn packs, JLPT Grammar, and the kana charts are free and work without an account. Writing Practice also works without an account, for a 1-character sheet. The Reading Assistant, Listening Practice, and Image Assistant need a free account. Signing in on a paid plan raises the limits, adds an AI switch to the header (see Turning On AI Features) and, on the Bunko and Sensei plans, unlocks the My Notes notebook and JLPT mock tests.
Open the hamburger menu. Tap the hamburger icon (the three stacked lines) in the header. Its contents depend on whether you are signed in:
Open My Account. Once signed in, the My Account page has a side menu with Current Plan, My Notes, Password & Security, Payment History, and Log Out. Throughout this guide, "open My Account" means opening the hamburger menu and clicking your account link.
Follow the cross-links. The tools hand off to each other so you rarely have to retype anything: the Image Assistant has a "Listen" button that sends the recognised text to Listening Practice, Listening Practice has "Read Along" to open the same text in the Reading Assistant, grammar points have "Dictionary", "Listen", and "Read" buttons, and every kanji has a "Practice" button that opens Writing Practice.
You do not need a Japanese keyboard. Every text box on Yomit.ai that accepts Japanese — the dictionary search, the Reading Assistant and Listening Practice text areas, note editors, and more — has a small あ / A toggle beside it that converts romaji to kana as you type.
Click the あ toggle next to a text box. Its tooltip reads "Japanese input off (click to type Japanese)" when off and "Japanese input on (click for English)" when on. Click it again (it will show A) to go back to typing plain English or romaji.
With Japanese input on, type romaji and it turns into hiragana immediately: tabemasu becomes たべます. Both Hepburn (shi, tsu, fu) and Kunrei (si, tu, hu) spellings are understood. Type nn, or a lone n followed by Space or Enter, for ん. Type a word entirely in capitals to get katakana instead: KOOHII becomes コーヒー.
To convert kana to kanji, press Space after typing a word. A list of kanji candidates appears with the hint "Space: next Enter: keep Esc: kana":
When you are signed in on the Kanji, Bunko, or Sensei plan an AI switch (with a magic wand icon) appears in the header beside the feature menu. AI is never used unless the switch is on, and everything works the same with it off — the standard dictionary, text recognition, and voice are always available.
With the switch on, the following appears across the site:
Click the AI switch in the header. Its tooltip reads "AI features are off, click to turn them on" or "AI features are on, click to turn them off". Your choice is remembered in this browser, so you only need to set it once.
AI explanations are on demand. The AI Explanation and In this sentence panels start collapsed with the hint "tap to ask the AI". Nothing is sent to the AI — and no tokens are used — until you expand the panel.
Every paid plan includes a monthly allowance of AI tokens. If you use the whole allowance before your billing period resets, AI features pause and you will see a message like "You have used all … AI tokens included in your … plan for this billing period". The Image Assistant and Listening Practice fall back to their standard engines automatically and tell you so. See Plans & AI Tokens for the allowance on each plan and how to check your usage.
The dictionary is the home page. It covers Japanese words, names, and kanji, and understands searches in Japanese, romaji, or English — including conjugated forms and whole phrases.
Type into the search box (its placeholder reads "食べる, taberu, or to eat") and press Enter or click the magnifying glass. You can search for:
食べる, たべる, コーヒー.taberu, benkyou.to eat, study.食べました finds 食べる and tells you which form it is.朝ごはんを食べました and it is split into words under the heading "Words in your phrase, tap one to look it up".* stands in for the rest. 駅* starts with 駅, *屋 ends with 屋, and *雨* has 雨 somewhere in the word. 電*車 starts with 電 and ends with 車.あお, 枚, 四十七, これ, or 父 still shows the dictionary, and asks whether you wanted the matching list.Search one kanji, or a short word written only in kanji, and a Hiragana row appears above the results with the reading of each character. Kun and on readings are both written in hiragana, and each reading is a link to the words that use it.
A search can be up to 200 characters. For longer passages use the Reading Assistant instead.
Read the results. The summary line tells you how many words and kanji matched (e.g. "3 words and 1 kanji for 食べる") and, for long result sets, which page you are on. Word entries are listed first, followed by a card for each kanji in your search. If nothing matched you will see "No words matched …" with suggestions, such as trying romaji, using the radical search, or pasting longer text into the Reading Assistant.
Use the two buttons beside the search box: 部 opens the radical search (see Finding A Kanji By Its Radicals) and ✕ clears the search. Use the あ / A toggle to type Japanese without a Japanese keyboard (see Typing Japanese).
Each word entry shows the headword with its reading, the part of speech, numbered meanings, and any Other forms (alternative spellings). Beneath the entry is a row of action buttons.
Click "Conjugate" (verbs and adjectives only). A Conjugations dialog opens with a table of Form, Affirmative, and Negative columns covering the polite, past, te-form, potential, passive, causative, conditional, volitional, and imperative forms.
Click one of the "Kanji" buttons — there is one for each kanji in the word — to open that character's details without running a new search. See Kanji Details & Stroke Order.
Click "Listen" to open the word in Listening Practice and hear it read aloud.
Click "Note" (Bunko and Sensei plans) to jot down something about the word without leaving the page. See Notes On Words, Kanji & Grammar.
With the AI switch on (paid plans), an AI Explanation panel appears above the results. Expand it to get a short explanation of the word you searched for — its nuance, typical usage, and how it differs from words with similar meanings.
A kanji card shows the character, its meanings, Kun and On readings, and quick facts such as "7 strokes · Grade 2 · JLPT N4 · #123 most used" and its radical. Kanji cards appear at the end of dictionary results for any kanji in your search, and open in a dialog when you click a "Kanji" button on a word entry.
Click "Details" to open the full Kanji dialog, which adds Names readings (nanori, used in personal names) and the complete list of readings and meanings.
Click "Stroke order" to open the Stroke Order dialog. The character is drawn stroke by stroke; click "Replay" to watch it again or "Practice Sheet" to open a printable sheet for this character in Writing Practice. Stroke order data comes from KanjiVG; for the rare character without data you will see "Stroke order data is not available for …".
Click "Practice" to jump straight to Writing Practice with this kanji filled in, or "Note" (Bunko and Sensei plans) to attach a note to the kanji.
When you can see a kanji but cannot type it — on a sign, in a book, in a photo — you can find it by picking the parts (radicals) you recognise in it. If the kanji is in a photo or screenshot, the Image Assistant can also read it for you.
On the dictionary page, click the 部 button beside the search box (tooltip "Find kanji by radicals"). The Find Kanji by Radicals dialog opens with the prompt "Select the radicals you can see in the kanji" and a grid of radicals grouped by stroke count.
Tap each radical you can see. The list of matching kanji beneath the grid, also grouped by stroke count, narrows with every selection under the heading "… kanji, tap one to add it to your search". You can combine up to 10 radicals. Click "Reset" to clear your selection and start again. If you pick a combination that no character contains you will see "No kanji contain all of the selected radicals."
Tap the kanji you were looking for. It is added to the search box, so you can keep adding characters to build a whole word before you search.
Searching a word shows the dictionary. When that word belongs to a collection, the page asks whether you wanted the list. Once a collection is open, the buttons under the search box switch between Body, Clock, Colours, Connectors, Counters, Demonstratives, Family, Feelings, Frequency, House, Numbers, Position, Questions, Time, and Weather. Tap a word or a reading to look it up in the ordinary way.
Body. The head, the face, the features, then from the neck down to the feet. お腹 is おなか. 足 is the foot and the leg. 着る is a shirt, 履く is trousers and shoes, かぶる is a hat, and 脱ぐ takes all three off. Some verbs sit in more than one box. 痛い, it hurts, is in Feelings.
Clock. Now, morning, midday, evening, and night, then a.m. and p.m., then half past and a little after. 朝 is あさ. 今日 and 今朝 stay in Time. 時 and 分 are in Counters. 三時半 is half past three, and 三時過ぎ is a little after three.
Colours. Basic colours, including オレンジ, and a set of traditional ones. The card is a light wash of the colour and the dot is the colour itself, so 白 and 黄色 stay readable.
Connectors. And, or, and but. と closes a list of nouns, や and とか leave it open, and か is or in the middle and a question at the end. A verb takes て, an い-adjective takes くて, and a noun or a な-adjective takes で. けど follows a verb or an い-adjective, and だけど follows a noun or a な-adjective. し is also a reading of 四, which stays in Numbers.
Counters. The counters learners meet, grouped by what they count: people, animals, shape, machines, buildings, time, books, food, clothing, groups, and money. Under each one is how it is read from one to ten. 歳 is how old someone is (二十歳 is はたち). 円 is the yen.
Demonstratives. The こそあど words that are not questions: これ, それ, あれ, ここ, そこ, あそこ, この, その, あの, こんな, そんな, あんな, こう, そう, ああ, then the polite こちら, そちら, あちら. こ is near you, そ near the other person, あ away from both. The ど row stays in Questions.
Family. The family as a whole, parents, grandparents, brothers and sisters, then uncles, aunts, cousins, in-laws, and children. Each card has the plain reading and the さん form: 父 is ちち, and お父さん is おとうさん. いとこ is a cousin, and the kanji is 従兄弟 for a boy and 従姉妹 for a girl.
Feelings. 好き and 嫌い, 元気, 忙しい, and 大丈夫, then glad, sad, fun, scary, painful, and tired. 好きな本 takes な. 大丈夫です is I am fine, and also that is all right. 疲れた is what you say; the dictionary form is 疲れる.
Frequency. Always, often, sometimes, and occasionally, then very, a little, and more. あまり and 全然 take a negative: あまり食べません, 全然分かりません. よく is often, and also well.
House. The building, the rooms, and the openings. 家 is いえ the building, and うち the home. 玄関 is where you take your shoes off. 台所 is the kitchen. お手洗い sits under トイレ.
Numbers. Type a whole number, up to 9999兆, and press Show. You get the kanji and the reading, then the same number with the common counters, so you can see that 3本 is さんぼん and 8本 is はっぽん. Below the converter are the digits, every day of the month (一日 is ついたち, 二十日 is はつか), and the twelve months.
Position. Right and left, above and below, in front and behind, inside and outside, next to and nearby, then east, west, south, and north. 東 is ひがし for the direction, and とう in names such as 東京. 後ろ is うしろ; あと is later, a different word.
Questions. 何, 誰, どこ, いつ, なぜ, どう, どれ, どの, どちら, どなた, なんで, どうして, いくら, and どんな. 何 is なに on its own and なん before a counter. 誰 is だれ. どちら is which of two, and いくら is how much.
Time. Today, tomorrow, and yesterday, then this week and this year, then the days of the week. 今日 is きょう, 明日 is あした, and 昨日 is きのう. 今年 is ことし. The other readings under each word are the formal ones. Morning, night, and half past are in Clock.
Weather. The four seasons, including 梅雨 as つゆ, then sunny, cloudy, rain, snow, and wind. 暑い is hot weather; 熱い is a hot drink. 寒い is cold weather; 冷たい is a cold drink. 暖かい is mild weather; 温かい is a warm meal.
The Reading Assistant takes any Japanese text — an article, song lyrics, a message from a friend — adds furigana above every kanji, splits it into words, and lets you tap any word for its dictionary entry without leaving the page. It is the best way to read material that is slightly above your level.
Paste or type your text into the large text box (its placeholder reads "日本語のテキストをここに貼り付けてください。"). The counters beneath it show how much of your character limit you have used and how many texts you have read this month; longer texts can be read in sections. Both limits depend on your plan: 100 characters at a time and 10 texts a month with a free account, up to 1,500 characters and 200 texts on the Sensei plan. The Reading Assistant needs an account: log in or register for free to use it. Click "Clear" to start over.
Click "Read". The text is redrawn with furigana and every word is colour-coded by part of speech — the legend beneath the text shows noun, verb, adjective, particle, adverb, and other. Untick "Show furigana" to hide the readings and test yourself; the setting is remembered.
Tap any word. A drawer slides in showing the word with its furigana, its part of speech, its dictionary form if it is conjugated, and up to four dictionary definitions. Verbs and adjectives that were conjugated in your text have a "Conjugate" button. Press Esc or click the ✕ in the drawer to close it.
With the AI switch on (paid plans), the drawer also has an In this sentence panel. Expand it to have the AI explain how this particular word is being used in the sentence around it — useful for particles, set phrases, and words with several meanings.
The Image Assistant extracts Japanese text from a picture — a menu, a sign, a manga panel, a screenshot — and shows it with furigana so you can tap any word to look it up. It needs an account: log in or register for free to use it. Every plan has a monthly allowance of images, from 10 with a free account up to 200 on the Sensei plan; every read counts, including reading a straightened picture again or a selected area. Your image is processed and then deleted; it is never stored.
Get the picture onto the page in whichever way is easiest:
Images must be JPEG, PNG, WebP, or GIF and smaller than 5 MB.
Check the preview (the file name and size are shown beneath it) and click "Read Text". If the picture contains no Japanese you will see "No Japanese text was found in the image. Try a sharper, closer, or better lit picture."
Work with the recognised text. It appears beside the image with furigana and tap-to-define words, just like the Reading Assistant. Use "Show furigana" to toggle readings, "Copy Text" to copy the plain text to your clipboard, and "Listen" to send it to Listening Practice.
A note under the results tells you which engine was used: "Text recognised with optical character recognition" (the standard engine, free for everyone) or "Text recognised with AI" when the AI switch is on. AI vision is noticeably better with handwriting, decorative fonts, and cluttered backgrounds. If your AI token allowance has run out, the standard engine is used instead and the note says so.
If the picture is tilted or on its side, drag the "Straighten" slider under the image until the line of text is level (the 90° buttons turn it by a quarter turn). Then drag a box around the part you care about. The selected crop is sent back to the standard reader, which often does a better job when it only has to look at a small upright area. The text on the right updates to that reading. Click the highlighted area, or press Esc, to drop the selection and restore the original text from the first reading.
Listening Practice reads any Japanese text aloud. Pick the JLPT level that matches you and the speech slows down or speeds up to suit, so you can train your ear on text you have just read.
Paste or type text into the text box (its placeholder reads "今日はいい天気ですね。"). The counters beneath the box keep track of your character limit and how many recordings you have made this month, both of which depend on your plan: 50 characters at a time and 10 recordings a month with a free account, up to 1,500 characters and 200 recordings on the Sensei plan. Listening Practice needs an account: log in or register for free to use it. Text often arrives here already filled in from a "Listen" button elsewhere on the site; those buttons use the same allowance.
Choose a speed. The options are labelled by JLPT level, from N5 - Slowest through N4 - Slow, N3 - Relaxed (the default), N2 - Natural, to N1 - Fast. Your choice is remembered for next time.
Click "Listen". An audio player appears; press play to hear the text, and replay as often as you like. Click "Download" to save the audio file to your device (handy for a playlist or flashcard app), or "Read Along" to open the same text in the Reading Assistant with furigana while you listen.
A note under the player tells you which voice was used: "Voice generated with Open JTalk" (the standard voice, free for everyone) or "Natural voice generated with AI" when the AI switch is on. The AI voice counts one AI token per character spoken; if your allowance has run out the standard voice is used instead.
Writing Practice turns kanji, hiragana, and katakana into a printable PDF practice sheet. Each character gets its own page with its readings (and, for kanji, meanings), faded stroke order guides to trace, and rows of empty boxes to fill in. Guests can make a sheet for 1 character with the standard layout; a free account allows 1 characters per sheet and 10 pages a month, and the paid plans unlock the sheet options, up to 25 characters per sheet, and up to 200 pages a month. A sheet counts as the pages it prints to: three characters at one per page use three pages of the allowance, three characters at three per page use one.
Type or paste text containing the kanji, hiragana, or katakana you want to practise (the placeholder reads "漢字・ひらがな・カタカナを入力してください。 Any text works, tap the characters below to choose which to practise."). You can paste a whole sentence or vocabulary list — punctuation is ignored and duplicate characters are counted once. How many different characters fit on one sheet depends on your plan (1 on the free Kana plan, up to 25 on Sensei); the counter beneath the box shows how many you have selected, and how many pages you have printed this month.
Check the row of character chips under the heading "Characters on your sheet, tap one to include or exclude it". Highlighted chips are on the sheet; tap one to add or remove it. If you paste more characters than your plan allows, none are selected until you tap the ones you want. If you are already at the limit, deselect one before adding another.
Click "Create Practice Sheet". The PDF opens in a new tab, ready to print or save. Practise the way the tips on the page suggest: top to bottom, left to right; use the guide lines; trace, then write from memory in the empty boxes.
The JLPT Grammar page lists grammar points for every level from N5 to N1, each with its meaning, usage rules showing how it attaches to verbs, adjectives, and nouns, and example sentences grouped by vocabulary level.
Pick a level with the N5 N4 N3 N2 N1 tabs. Each tab shows how many points it contains. The list beneath shows every point at that level with its pattern, meaning, and a preview example.
Or search. Type into the search box (placeholder "Search patterns, meanings, or examples (e.g. ながら, because, てもいい)", up to 100 characters). The search matches patterns, English meanings, and example sentences across all levels, and jumps to the first level with a match. The heading tells you what matched, e.g. "4 N4 grammar points matching ながら".
Tap a grammar point to expand it. You will see:
Expand "Key: how to read the usage rules" at the top of the page if the terminology is new to you. It explains what "Verb", "Verb stem", "Verb dictionary-form", "い-adjective stem", "Plain form" and the rest mean, and when a noun needs だ, な, or の.
The level, search term, and page you are viewing are kept in the address bar, so you can bookmark a view or send the link to a study partner.
The Learn page is a set of short packs for a beginner, and for anyone about to visit Japan. Open it from the dictionary home page. It is free and needs no account. The tabs along the top switch between the packs.
Phrases is nine situations: arriving, the station, a restaurant, a convenience store, being stuck, a hotel, paying, finding your way, and a pharmacy. Each line has the Japanese with furigana, an English phonetic reading under every word (こんにちは has kon-ni-chi-wa under it), the English, and a note on when to say it. Lines marked You will hear this are what staff say to you. A word that belongs to a dictionary collection has a link to that list. Tap a word to open it in the dictionary. Listen reads the line aloud at a slow speed. Read opens it in the Reading Assistant.
Signs is the words on doors, stations, and shop windows, such as 出口, 営業中, and 税込. The kanji underneath are the ones those words are written with. Tap a character for its readings, meanings, and stroke order.
Kanji repeats those sign characters, then lists the eighty kanji taught in the first year of Japanese elementary school, most common in newspapers first. Practice sheet sends the set to Writing Practice. Your plan still decides how many characters can be printed at once.
Politeness shows the same request three ways: with friends, at the counter, and when you want to be careful. Reading is short texts built from the phrases.
Phrase for today and Kanji for today change at midnight in Japan. They also appear on the dictionary home page.
The Hiragana and Katakana pages hold the complete charts for both scripts: the basic table, the dakuten and handakuten rows (が, ぱ …), the combination sounds (きゃ, しゅ …), and, for katakana, the extended combinations used for foreign words (ヴ, ファ, ティ …).
Use the two toggles above the chart. "Show romaji" (on by default) displays the reading under each character; turn it off to test yourself. "Show how to type" displays the keys to press to produce the character with Japanese input (see Typing Japanese). Both settings are remembered.
Tap any character to open its Stroke Order dialog and watch it drawn stroke by stroke. Click "Replay" to see it again.
Click "Quiz Me" to test yourself. Pick which tables to include (the basic sounds, dakuten and handakuten, combinations, and for katakana the extended sounds), how you want to be asked (see the kana and pick the romaji, see the romaji and pick the kana, or see the kana and type the romaji), and how many questions. Right answers move on by themselves; a wrong answer shows the correct reading before the next question. The number keys 1–4 pick a choice and Enter moves on. Both Hepburn and kunrei spellings are accepted when typing (shi or si, tsu or tu).
At the end you see your score and the characters you missed; tap one for its stroke order, or click "Review Missed" to drill only those. Your best streak of correct answers in a row is remembered in your browser. The quiz is free for everyone, including guests, and nothing is saved to an account.
Use the "Katakana Chart →" (or "← Hiragana Chart") button at the bottom of the page to switch between the two scripts.
The JLPT Practice page builds a full-length mock test at any level from N5 to N1, with the same parts, question types, and number of questions as the official Japanese-Language Proficiency Test. You can take a generated test as many times as you like, sitting each attempt as Practice or under Exam conditions, and every finished attempt is scored overall and by section so you can watch your progress.
Mock tests are included in the Bunko and Sensei plans, which let you generate 1 new test per billing period. The Sensei plan also shows an explanation for every question when you review your results. Guests and other plans can see the page but cannot generate a test.
Generate a test. Under Generate a new mock test, pick a level. Each level shows how many questions the test has and how long the official exam allows. Click "Generate Mock Test"; when it is ready you are taken straight to it. The counter beside the button reads "X / Y tests generated this billing period" with the date it resets. If you have used your allowance you will see "You have generated all … mock tests included in your plan for this billing period", but you can still retake every test you already have.
Occasionally a test is marked shortened. That means the question bank could not fill every part at that level when it was generated; the test overview shows exactly which parts and question types are included.
Read the overview and choose how to sit the test. The test page lists each part of the exam — Language Knowledge (vocabulary and grammar), Reading, and Listening — with its official time limit, the number of questions, roughly how long that allows per question, and the question types it contains. Choose Practice to sit at your own pace, or Exam conditions to be timed to those official limits; when exam time is up the test is submitted for you. Click "Start Test" when you are ready.
Answer the questions. The question palette on the left lists every question grouped by part; answered questions are filled in, and you can click any number to jump to it. Use "Previous" and "Next" to move through the test and pick one of the numbered choices for each question. Reading passages stay on screen for every question that belongs to them. Listening questions have an audio player — press play, listen as often as you need, and then answer. In Practice a stopwatch shows how long you have been answering; under Exam conditions a countdown shows how much of the official time is left.
Stop and come back later if you need to. Every answer is saved as soon as you pick it. In Practice, click "Save and leave" — that is the way to pause, not "Finish Test". Under Exam conditions, "Leave exam" keeps your answers and continues the sitting as Practice, so an interruption does not score a half-finished exam. The test is then marked "Resume" on the JLPT Practice page; "Resume Attempt" takes you to the first unanswered question, and "Abandon Attempt" throws the attempt away so you can start fresh.
Finish and review. Click "Finish Test" only when you want the sitting scored. If any questions are unanswered in Practice you can save and leave instead of submitting; under Exam conditions unanswered questions count as wrong, including when time runs out. The results page shows whether the sitting was Practice or Exam conditions, your overall percentage, a bar for each section, and every question marked Correct, Wrong, or Unanswered with the correct choice highlighted beside your answer. Click "Show Only Mistakes" to hide the questions you got right, and expand "Show the script" under a listening passage to read what was said. On the Sensei plan each question also has an Explanation of why the answer is right.
The official JLPT converts raw answers into scaled scores and requires a minimum in every section as well as an overall pass mark, so treat these percentages as a guide to where you stand rather than a prediction of your result.
Retake and track your progress. Click "Take This Test Again" on the results page, or "Take Again" on the JLPT Practice page; the questions and answer order are the same every time, so study the ones you missed first. You choose Practice or Exam conditions again each time you sit it. Back on the JLPT Practice page, Your progress charts every finished attempt by level (exam sittings in teal) with a table of overall, Language Knowledge, Reading, and Listening scores and a Review link for each, and Strengths and weak spots shows how you have done on each question type across all your attempts — the lowest bars are where extra study pays off most.
My Notes is your own study notebook. Jot down notes about words, kanji, and grammar as you look them up, organise them into books and pages, and let the AI polish them or quiz you on them.
My Notes is included in the Bunko and Sensei plans. On other plans the "Note" buttons are hidden and the hamburger menu shows Upgrade Plan in place of My Notes.
The notebook has three levels:
Open My Notes from the hamburger menu, or from the My Notes link in the My Account side menu. The page has a sidebar on the left and your notes on the right.
Pick a view at the top of the sidebar. Each shows a count of the notes in it:
Beneath the views, the Books section lists your books; expand a book to see its pages and click a page to see the notes on it.
Reorder anything by dragging. Books in the sidebar, pages within a book, and notes on a page each have a drag handle (tooltip "Drag to reorder"). Drag to the position you want and the new order is saved immediately.
Books hold pages, and pages hold notes. You can write notes without any books at all (they stay in Unfiled), but books and pages make a large notebook much easier to navigate and are what you export when you want to take your notes with you.
Create a book. Click "New book" beside the Books heading in the sidebar. In the dialog, enter a Book title (e.g. JLPT N4, Travel phrases; up to 255 characters) and, optionally, a description under "What is this book for?" (up to 1,000 characters). Click "Save".
Add pages to the book. Hover over the book in the sidebar to reveal its icons: show or hide the pages, New page, Rename book, Export book, and Delete book. Click New page, enter a Page title (e.g. Week 3 vocabulary), and click "Save". A book with no pages yet shows "No pages yet. Add the first page".
Rename or delete a page. Click a page in the sidebar to open it. The toolbar above the notes gains "Rename" and "Delete" buttons for that page (plus "AI", covered in Using AI With Your Notes).
Deleting a page or book asks you to confirm first — "Delete the page …?" or "Delete the book … and its N pages?". Deleting a page or book removes the pages and notes inside it; there is no undo, so export the book first if you might want the notes later.
Notes are written in a simple editor with Markdown formatting. Notes are saved when you click "Save" — there is no autosave — so save before leaving the page or asking the AI to work on a note.
Click the blue "New note" button in the toolbar. If you have a page open, the new note is filed on that page automatically.
Fill in the editor:
**bold**, *italic*, `code`, - lists, # headings. Both fields have the あ / A Japanese input toggle.Click "Save", or "Cancel" to discard. If you try to save an empty note you will see "Please write something in the note first".
Each saved note appears as a card with its title, the rendered Markdown, a Book › Page link if it is filed, the last-updated date (hover for the created date), and three buttons: "Edit" reopens the editor, "AI" opens the AI dialog, and "Delete" removes the note after a "Delete this note?" confirmation. To move a note to a different page, click "Edit" and change File on page.
The quickest way to build your notebook is to write notes while you study. Word entries and kanji cards in the dictionary and grammar points on the JLPT Grammar page all have a "Note" button (Bunko and Sensei plans). Notes made this way are attached to the word, kanji, or grammar point, so you will see them again the next time you look it up.
Click "Note" on a word, kanji, or grammar point. A dialog titled "Notes: …" opens listing every note you have already written about it (or "You have no notes about this yet.").
Under Add a note, write what you want to remember (the placeholder reads "What do you want to remember about …?"), optionally pick a page under File on page, and click "Save". Click an existing note in the list to switch the form to Edit note.
Click "See all your notes" at the bottom of the dialog to open My Notes. Attached notes show a reference pill (e.g. About 食べる) on their card and are collected in the Dictionary & grammar view in the sidebar. Editing an attached note in My Notes keeps it attached.
On the Bunko and Sensei plans the AI can work on a single note or on every note on a page. Each request counts against your monthly AI token allowance (summarising or quizzing a page of notes is typically a few thousand tokens). The AI reads your saved notes, so save any changes first — otherwise you will see "Save your changes first, the AI works from the saved note".
Open the AI dialog. Click "AI" on a note card to work on that note, or open a page and click "AI" in the toolbar to work on the whole page. The dialog, titled Ask the AI, asks "What should the AI do with …?"
Choose what to do and click "Run":
Up to 12,000 characters of your notes are sent as context; on a very long page, notes beyond that point are left out, so split large pages if you want everything covered.
Use the result. It appears in a panel above your notes. For an improved note, click "Use this version" to open the note in the editor with the new text so you can check it before saving. For any result, click "Save as a new note" to keep it as its own note on the same page. Click the ✕ to dismiss the panel.
Improve while writing. Inside the editor, the "Improve with AI" button runs Improve this note on the note you are editing. Save first — the button works from the saved copy.
On the Sensei plan you can download any book as a file you can keep, print, or share. Exports are per book and include every page and every note in it, with Japanese text rendered correctly in all three formats.
On the Bunko plan the Export book icon is shown but exporting asks you to upgrade: "Exporting your notes to PDF, Word, and Excel is included in the Sensei plan".
In My Notes, hover over the book in the sidebar and click the Export book icon. The Export book dialog opens with a summary such as "Export the book "JLPT N4" (6 pages, 42 notes) as a file you can keep, print, or share."
Choose a format:
Click "Export". The file is generated and downloaded by your browser. Notes that are Unfiled do not belong to any book, so file them on a page first if you want them included.
You do not need an account to use the dictionary, Learn packs, JLPT Grammar, or the kana charts. Writing Practice also works without an account, for a 1-character sheet. A free account unlocks the Reading Assistant, Listening Practice, and Image Assistant, and raises the Writing Practice sheet size and monthly page allowance. A paid plan adds the AI features and, on the higher tiers, My Notes and JLPT mock tests. New accounts start on the free Kana plan. Sign in with your e-mail address and password; there is no Google sign-in on the login page.
Register. Click Log in in the header, then follow the link to register, or go straight to the Register page. Fill in Name, Username (e-mail address), Password, Confirm Password, and the Captcha (click the refresh icon if it is hard to read), then click "Register". An activation link is emailed to you; click it within five days to activate the account.
Log in. Click Log in in the header and sign in with your e-mail address and password. If you have 2-factor authentication enabled you will be asked for the six-digit code from your authenticator app next. Links to Forgot Password and Login Trouble are on the login form if you need them.
Change your display name. On the My Account page, click your name at the top of the side menu, type a new one, and press Enter (or click elsewhere) to save it. The name appears in the hamburger menu as "…'s Account".
Log out with the Log Out link at the bottom of the My Account side menu.
Every plan starts with the full dictionary and study toolkit, free. Move up a tier for AI on every lookup, a notebook of your own, JLPT mock tests, and files you can take with you. Plans are billed monthly and you can change or cancel whenever you like from the Plans & Pricing page.
What is an AI token? Tokens are the units the AI reads and writes in — roughly three quarters of an English word, or about one Japanese character. As a guide, a word explanation is roughly 1,100 tokens, summarising or quizzing a page of notes is a few thousand, reading a photo is about a thousand, and the natural AI voice counts one token for every character it speaks. Unused tokens do not carry over to the next month.
Check your usage. Open My Account. The AI tokens section reads "you have used X of Y AI tokens this billing period, your allowance resets on …" with a progress bar that turns red once you pass 90%. Below it, Daily AI Usage (last 30 days) lists the number of AI requests and tokens used each day. The same information is shown on the Plans & Pricing page.
When the allowance runs out, AI explanations and AI note tools pause until your billing period resets, while the Image Assistant and Listening Practice switch back to their standard engines automatically. Everything that does not use AI keeps working as normal. If you regularly run out, move up a tier for a larger monthly allowance.
Plan changes take effect immediately. When you upgrade you are charged the new plan's price and your AI allowance changes straight away; when you downgrade, paid features stay available until the end of the period you have already paid for. Payments are not refunded.
Open the Plans & Pricing page (from the Pricing or Upgrade Plan link in the hamburger menu, or the Current Plan link in My Account). Your plan's card is marked "Your current plan"; the others show "Choose …" for an upgrade or "Switch to …" for a downgrade. Click the button on the plan you want.
On the checkout page, headed "Changing Plan from … to …", enter your card details (Credit Card Number, Card Verification Code, Expiration Date) and billing address. If you have a Promotional Code, enter it and click "Apply" to see the discounted TOTAL. Click "Change Plan" to confirm. Switching to the free Kana plan skips the payment form.
Cancel by switching to the Kana plan. You keep your account, and your notes are kept too — My Notes is simply unavailable until you return to a plan that includes it. If you would like a copy of your notes first, export your books while you are still on the Sensei plan.
Find a receipt. Open My Account and click Payment History in the side menu. Every payment is listed with its date and total; click "View Receipt" to open the payment detail page, which shows the card type, masked card number, billing address, any promo code, and the PAYMENT TOTAL. Click "Receipt" there for a printable version.
The Password & Security page (reached from the My Account side menu) lets you change your password and protect your account with a 2-factor authentication (2FA) app. The form lists Google Authenticator; any app that can scan the QR code will work.
Change your password. Enter your Current Password, then the new Password and Password Confirm. If 2FA is enabled a Code field also appears — type the code you see in your authenticator app. Click "Submit". Changing your password signs out every other device that was logged in to your account.
Enable 2FA. Click "Enable 2-Factor Authentication". In step one, choose your Authenticator App from the list and scan the QR Code with it (or type the secret in manually), then click "Next". In step two, enter your account Password and the six-digit Code the app now shows, and click "Submit". From now on, logging in asks for a fresh code after your password.
Disable 2FA. Click "Disable 2-Factor Authentication", confirm with your password and a current code, and click "Submit".
Forgotten your password? Click Forgot Password on the login form and enter your e-mail address. The link you receive brings you back to this page to set a new password without needing the old one. If you have also lost access to your authenticator app, use Login Trouble on the login form and include your username. The Contact Us form is only available after you sign in.
Everything on Yomit.ai is also available to developers through a REST API — dictionary and kanji lookups, the dictionary collections, kana conversion, conjugations, grammar, the Reading, Image, Listening, and Writing tools, My Notes, and your account and payment details. The full reference, with examples in cURL, Go, PHP, Python, and Ruby, is on the API page. Requests use the same plan entitlements as the website: AI endpoints need a paid plan, notes endpoints need the Bunko or Sensei plan, and export needs Sensei.
Create a token. While signed in, open the API page and click "Create Token". Your token appears in the Your Token field. Each account has one token; keep it secret, as anyone who has it can act as you.
Use the token. Send it in an Authorization: Bearer <token> header on every request over HTTPS. Requests are limited to 200 every two minutes per address; the API returns 429 if you exceed that and 401 if the token is missing or wrong.
Rotate or remove the token. Click "Regenerate Token" to replace it with a new one (the old token stops working immediately), or "Delete Token" and confirm "Are you sure?" to remove API access entirely.
