Speaking practice inside the reader
Japanese shadowing practice: read the article, then speak it
Turn the article you're already reading into a sentence-by-sentence shadowing session. Tap the mic, listen to the native TTS, repeat aloud, then try the final repetition from memory.
- Listen → repeat → recall. A short countdown starts each sentence, followed by repeated native audio while you speak along.
- Blind recall with an escape hatch. The text fades for the final repetition, but you can hold the eye button to peek whenever you need it.
- Practice what was hard. Mark a sentence as difficult and YoMoo quietly flags it for a later weak-sentence review.
- Pick up where you left off. Resume an article, jump to a sentence, adjust playback speed, or look up a word without leaving the session.
Shadowing is speaking practice, not pronunciation scoring: YoMoo does not record your voice or grade your accent. The difficulty check is your own self-report.

JLPT level guide
Japanese reading practice for JLPT N5 to N1: who YoMoo is for
YoMoo covers every level of the official JLPT level guide, from N5 through N1, but it shines for learners who can already read kana (typically N4 through N2; Kana Challenge teaches kana first). If unedited NHK feels impossible on day one, that's not a bug: read the simplified N4–N5 version first. Starting out? See the best Japanese reading apps for beginners. Aiming at N3? Follow the JLPT N3 reading practice plan.
How it works
How YoMoo works in 3 steps
YoMoo puts four jobs that usually live in separate tools in one place: finding Japanese to read, making it readable, checking what words mean, and reviewing what you saved.
1. Choose Japanese you want to read
Pick built-in content by source and level, or paste, import or scan Japanese you already have. YoMoo analyzes text that was not written for learners.
Example: paste a news paragraph and every kanji gets furigana.2. Tap any word to understand it in place
Furigana, dictionary entries, JLPT level, text-to-speech and English translation open without leaving the reading view.
Example: tap 文章 to see ぶんしょう, “sentence · text · writing” and JLPT N3.3. Save words and review them later
Save a word with its reading, definitions, JLPT level and part of speech. Saved words enter a spaced-repetition queue, and you can export to AnkiDroid or CSV.
Example: a word saved today returns at 4h, 8h, 24h, 3d, 1w and 1m intervals.

FAQ
Frequently asked questions about YoMoo
Answers about price, platforms, levels, offline use and how YoMoo compares.
What is YoMoo and what can I do with it?
YoMoo is a Japanese reading app and browser text analyzer that adds furigana, tap-to-define dictionary lookups and JLPT levels to news, graded passages and any text you paste or import. You can also listen with text-to-speech, practice sentence-by-sentence shadowing, scan Japanese with your camera and save words to a spaced-repetition review queue. It is available on Android, on iPhone and iPad, and in the browser.
Is YoMoo free?
Yes, YoMoo is free to use without an account, and furigana, the dictionary, text-to-speech, JLPT passages and SRS vocabulary review are all included. On Android and iOS you get 5 free articles in total, then a short rewarded ad makes the next one available; on the web version it is 1 new article per day. An optional ad-free subscription removes the ads. Reading progress and saved words are stored locally, and the dictionary is bundled with the app.
Is YoMoo related to Yomu Yomu or other reading apps with similar names?
No, YoMoo is not related to Yomu Yomu: YoMoo is made by My Senpai in Tokyo, and Yomu Yomu is a separate app from a different developer. Both names come from the Japanese verb 読む (yomu, “to read”), which is why several unrelated reading apps sound alike. YoMoo is built for reading real Japanese, meaning news, Aozora literature, Japanese Wikipedia and any text you paste or import, with furigana and a tap-to-define dictionary. Yomu Yomu's App Store listing describes a library of stories written for learners, so the two apps work differently. For a side-by-side look at several options, see the best Japanese reading apps for beginners.
Can I use YoMoo on Android, iPhone or in a browser?
Yes, YoMoo is available on Android (Google Play), on iPhone and iPad (App Store) and in any browser through the Japanese text analyzer. The versions differ in a few places: free article allowances differ, Android uses the system text-to-speech voice and on-device camera OCR, and the web version runs OCR in the browser after its recognition engine loads.
What JLPT level do I need to start using YoMoo?
You can use YoMoo at any JLPT level from N5 to N1, as long as you can read hiragana and katakana. Most content targets N4 through N2, for learners who know some Japanese but struggle with native text. N5 and early N4 learners should start with the JLPT practice passages and the simplified N4–N5 versions of news articles. If you cannot read kana yet, start with Kana Challenge.
How does YoMoo help with Japanese reading practice?
YoMoo helps you read Japanese by keeping every lookup inside the text, so checking a word takes a tap instead of leaving the page. Furigana is already above the kanji, the dictionary opens as an overlay, and text-to-speech lets you check your reading. Saved vocabulary enters a spaced-repetition queue automatically.
Does YoMoo work offline?
Partly: YoMoo's dictionary (170,000+ entries), saved vocabulary, SRS queue and JLPT practice passages work offline after the first download. Live news, Wikipedia and on-demand translations need internet, then cache for 30 days. Camera OCR works offline on Android, while the web version runs OCR in the browser and needs its recognition engine loaded first.
Can I import my own Japanese content into YoMoo?
Yes, YoMoo can analyze your own Japanese: paste any text, upload PDF, DOCX or PPTX files, drop in an SRT subtitle file (useful for anime), or scan with camera OCR. Imported content gets the same furigana engine, dictionary lookups, TTS, vocabulary saving and translation as built-in articles.
What is shadowing mode in YoMoo?
Shadowing mode turns any YoMoo article into sentence-by-sentence speaking practice: a countdown starts, native TTS plays the sentence, and you repeat it aloud for a set number of repeats. On the final repeat the text fades for recall, with an eye button to peek, and you then report how the sentence felt so hard ones are flagged for later review. YoMoo does not record your voice or grade your accent. Sessions remember progress and support playback-speed changes, translation and dictionary lookups.
How does YoMoo's SRS compare to Anki?
YoMoo's SRS reviews saved words at 4h, 8h, 24h, 3d, 1w and 1m intervals, with a multiple-choice quiz mode and a self-rated flashcard mode. It is designed for zero-friction saving while reading: tap a word, tap save, and it joins the queue. If you already use Anki, you can export to AnkiDroid or UTF-8 CSV at any time. You can run both: YoMoo for review tied to your reading, Anki for existing decks.
How is YoMoo different from Todai?
Todai is a simplified-news reader, while YoMoo adds furigana on any text you give it, an offline dictionary, full SRS with Anki export, camera OCR, PDF and DOCX import, Aozora literature and Japanese Wikipedia. YoMoo also pre-simplifies its own news to N4–N5 alongside the original, so you can read the same story at either level in one app.
How do I get help or report a problem with YoMoo?
You can email the My Senpai team at [email protected] or leave feedback in your Google Play or App Store review. Say which device you use and what you were reading so the problem can be reproduced.
