Learn Japanese while you browse
FluentTab turns every Japanese page you read into a lesson. Select a word or a sentence and the translation that fits this sentence appears right where you are looking — with its reading, and a grammar explanation written for that exact line.
Three scripts, no spaces between words, and particles that carry the grammar — Japanese is where a dictionary lookup helps least and context helps most.
What it explains in Japanese
Hover the translation and a patient teacher appears. The explanation is written for the sentence in front of you, not copied from a textbook chapter:
- romaji reading for every word, so you can say it before you can read it
- particles — は, が, を, に — and what each one is doing here
- verb forms: plain, polite, te-form, and which register this is
- kanji readings that change with the compound they sit in
Everything you get for Japanese
- Context-aware translation. FluentTab reads the surrounding sentence before answering, so you get the meaning that belongs here — not a dictionary's first entry.
- Grammar in context. Why this ending, this case, this word order — for this sentence.
- Native pronunciation. One tap reads the selection aloud in a clear, consistent Japanese voice.
- A voice tutor that sees your page. One keystroke starts a spoken conversation about the text you just highlighted. Ask what it means, practise saying it, get corrected.
- Explanations in your language. Learning Japanese from Spanish, Japanese or any of the nine? Every answer arrives in the language you already speak.
- Private by design. The model runs on your device. What you read never leaves your browser.

Japanese questions
How does FluentTab help me learn Japanese?
FluentTab is a free Chrome extension that turns anything you read in Japanese into a lesson. Select a word or sentence on any webpage and it shows a translation chosen for that sentence's meaning, and a grammar explanation written for that exact sentence. You can also hear it read aloud in a native voice, and talk about it with an AI voice tutor that already knows what you highlighted.
Does FluentTab show readings for Japanese?
Yes. FluentTab gives you a romanised reading alongside the original script — selecting "りんご" shows "りんご (ringo)" (the apple) — so you can pronounce a word before you can read it, and the grammar explanation tells you what each particle and ending is doing in that sentence.
Is there a free Chrome extension for learning Japanese?
Yes. FluentTab is free to install from the Chrome Web Store, and all of its Japanese reading features — translation, grammar explanations and read-aloud pronunciation — are unlimited and free forever, with no account required. Only the live voice tutor is metered, and the free plan includes 30 minutes of it per month.
Can I read Japanese news and articles with FluentTab?
Yes. FluentTab works on every website, including content inside embedded readers and online-course viewers. It is built for learning from real Japanese material rather than flashcards: it stays hidden until a word stops you, answers in place, and disappears the moment you deselect, so you keep reading at nearly full speed.
Does FluentTab send what I read in Japanese to a server?
No. Japanese translations, grammar explanations and text-to-speech are generated by an AI model running locally on your own device inside the browser. The pages you visit and the text you select never reach FluentTab's servers and are never logged, profiled or sold.
Learn another language
FluentTab supports nine languages, in any pair. Explanations always arrive in the language you already speak.
