Tap any word for its reading, meaning and JLPT level.

Article: Wikinews, CC BY 2.5, translated into Japanese and simplified by YoMoo. Easy is written by AI from the original; details can differ, and Original is the source wording. Readings, meanings and levels come from the app's own dictionary.

Japanese news at your level: switch any article to Easy

Every news article in YoMoo comes in two versions. Original is the full news Japanese. Easy is a shorter, simpler rewrite of the same story with everyday words and plain grammar, so you can read the news before you are ready for the original.

YoMoo Library with JLPT reading practice tiles for N5 to N1, 65 passages each, and the content library list

Turn your own Japanese into a lesson: emails, documents, menus and AI-written stories

Many YoMoo learners skip the Library. They bring the Japanese they need or care about: a work email, a document, a restaurant menu, or a story an AI wrote about their hobby. Paste it or scan it, and YoMoo turns it into a lesson with furigana, JLPT colours, one-tap meanings and words to review. Your own text is always free.

Japanese emails

Paste a work or school email and read it properly before you reply. Every word gets its reading, and a tap gives the meaning: 打ち合わせ is a meeting, marked N1. Save the phrases you will need again, and they come back in review.

Stories an AI wrote for you

A growing number of learners ask ChatGPT, Gemini or Claude to write Japanese about what they love, at their level, then paste it into YoMoo. The result is reading practice nobody else has: your hobby, your level, with every word explained.

Documents

Copy the text out of a document, PDF or web page and paste it, or open a .txt file. Printed pages can be scanned with the camera. PDF and Word files cannot be opened directly yet.

Menus, signs and notices

Take a photo or pick one from your gallery. YoMoo reads the Japanese on your phone, then shows you the text to check before you tap Analyse. Recognition can misread less common kanji, so compare it with the photo.

Make your own lesson with an AI chat

  1. Ask ChatGPT, Gemini or Claude for Japanese at your level, on a topic you like. Start from this prompt:

Write a short story in Japanese for a JLPT N4 learner about [your hobby]. Use about 200 characters, short sentences and everyday words. Do not add furigana, romaji or an English translation.

  1. Copy the Japanese it writes.
  2. In YoMoo, tap Paste Japanese text, paste, and tap Analyse.
  3. Tap the words you do not know and save them. They come back for review.

Asking for no furigana or romaji keeps the text clean, because YoMoo adds the readings itself. AI-written Japanese can contain mistakes, and YoMoo shows readings and meanings from its dictionary without checking the grammar, so treat it as practice material and ask the AI to rewrite anything that reads oddly.

Save words as you read, then review them before you forget

Looking a word up is only half the job. YoMoo keeps every word you save, brings it back when it is due, and reminds you when there is something to review.

  1. Word sheet for 作る: reading つくる, as written 作ります, polite, N5, meanings to make, to produce, to manufacture, and a Save to Vocabulary button

    Tap and save

    The word sheet shows the reading, meanings and JLPT level. Conjugated verbs open at their dictionary form, so 作ります becomes 作る, marked polite.

  2. Review card for 作ります with the reading, meanings, and Again and Got it buttons

    Review with spaced repetition

    Saved words come back when they are due. Answer Again or Got it. Once you have four words, a quiz and flashcards open too.

  3. After saving a word, YoMoo asks: Want a nudge when these words are ready to review? Remind me, or Not now

    Get a nudge, if you want one

    After your first saved word, YoMoo offers a reminder for when words are due. At most one a day, and you can turn it off in Settings.

  4. YoMoo Home with Continue reading, Words due, and a reading streak

    Pick up where you stopped

    Home opens on the article you were reading, the words due today and your reading streak.

Export your words to Anki

Vocab, then Manage words, then Export words (CSV). The file puts the word and its reading first, so it imports straight into Anki or opens in a spreadsheet. Available on Android now, and on iPhone with the next update.

Vocab screen with the Manage words sheet: Select words, Export words (CSV), Remove all words

Listen and repeat what you just read

The microphone button turns any article into shadowing practice: hear a sentence, repeat it aloud three times while it plays, and on the last round the text disappears so you recall it from the audio. Speed goes from 0.75× to 1.1×. YoMoo does not record or score your voice. For scored speaking practice, use FluencyTool.

YoMoo or a news site and a dictionary app?

Most learners start by reading the news with a dictionary app open beside it. This is what changes when the help sits inside the text.

YoMoo questions and answers

Is YoMoo free?

Yes. YoMoo is free to download and needs no account. Furigana, the dictionary, text-to-speech, saving and reviewing words, Aozora Bunko and your own text are free with no limit. On the phone apps, 5 news, JLPT passage or How-To articles are free in total, then a short ad unlocks each new one. An optional ad-free subscription removes the ads and the limit.

Do I need to know hiragana and katakana first?

Yes. YoMoo adds furigana above kanji, and furigana is written in hiragana, so you need to read kana before YoMoo helps. Kana Challenge, also by My Senpai, teaches both kana sets first.

What is the Easy version of an article?

Easy is a shorter, simpler rewrite of a news article, written by AI from the original, with everyday words and plain grammar. Details can differ from the news report, so the Original version is always one tap away. You can make Easy the default in Settings.

What can I read in YoMoo?

JLPT practice passages for N5 to N1 (65 per level), current news in eight topics with Original and Easy versions, 400 How-To articles, 500 Aozora Bunko literature texts, and any Japanese text you paste, scan or open from a file.

Can I read my own Japanese text in YoMoo?

Yes. Paste text, scan a printed page or a photo with the camera, or open a text or subtitle file (.txt, .srt or .vtt). YoMoo adds furigana, JLPT colours and one-tap meanings to it. PDF and Word files are not supported. Your own text is always free.

Can YoMoo help me read Japanese emails, documents or menus?

Yes. Paste an email or the text of a document, open a .txt file, or scan a printed page, menu or sign with the camera. The text becomes a lesson with furigana, JLPT colours and one-tap meanings, and your own text is always free. Text recognition can misread less common kanji, so check the scanned text before you analyse it. PDF and Word files cannot be opened directly; copy their text and paste it.

Can I use YoMoo with ChatGPT, Gemini or Claude?

Yes. Ask the AI to write Japanese at your level about a topic you like, without furigana or romaji, then copy the text and paste it into YoMoo with Paste Japanese text. YoMoo adds furigana, JLPT colours and one-tap meanings, and the words you save come back for review. AI-written Japanese can contain mistakes and YoMoo does not check grammar, so treat it as practice material.

Is YoMoo good for JLPT reading practice?

Yes. The Library has 65 reading passages for each JLPT level from N5 to N1, and every word in every text is coloured by its JLPT level, so you can see at a glance how much of a text sits at or below your level.

Where does the YoMoo dictionary come from?

YoMoo uses JMdict and JMnedict, the open Japanese dictionary projects (CC BY-SA 4.0), with more than 250,000 words and readings built into the app. Conjugated verbs open at their dictionary form, so 作ります shows as 作る, marked polite.

Can I export my YoMoo words to Anki?

Yes, on Android: open Vocab, then Manage words, then Export words (CSV). The file lists the word and its reading first, so it imports into Anki or opens in a spreadsheet. The iPhone app gets the export in its next update.

Does YoMoo record my voice?

No. YoMoo has a listen-and-repeat shadowing mode for any article, but it does not record or score your voice. For speaking practice that scores what you say, use FluencyTool, also by My Senpai.

Is there a web version of YoMoo?

Yes. YoMoo runs in the browser at my-senpai.com/analyzer/yomoo/ with the same reader and dictionary. The web version opens 1 new article a day; the phone apps have more.

Who makes YoMoo?

YoMoo is made by My Senpai, a small team in Tokyo that also makes Kana Challenge, FluencyTool and Japanese Crossword. You can reach the team at [email protected] or through a Google Play or App Store review.
