Japanese text analyzer
Split a Japanese sentence into words and get the reading, meaning and JLPT level of each one. This is the tool you need once you can read kana but cannot tell where a word starts and ends.
How it works
- Paste a sentence, however long.
- Every word becomes clickable, coloured by JLPT level.
- Tap a word for its full entry, or add it to your review cards.
An example, rendered by the engine
These sentences are analysed by the same engine as the app, at site build time.
漢字が読めなくても、日本語は読める。Open this sentence in the reader
今日は天気がいいので、公園まで歩きました。Open this sentence in the reader
彼女は毎朝六時に起きて日本語を勉強しています。Open this sentence in the reader
Japanese has no spaces
This is the difficulty nobody warns beginners about: 「今日はとてもいい天気ですね」 shows no visible boundary, and a wrong split gives a wrong reading. The analyzer explores every possible segmentation and keeps the most likely one, preferring long words, recognising particles and penalising splits that multiply short fragments.
Frequently asked questions
Can I analyse text copied from a website?
Yes. The browser extension even does it directly on the page, with no copy and paste.
Does it work offline?
In the Android app, entirely. On the web the dictionary is cached after the first load.
