Common questions.
The questions that come up most. If yours isn’t here, write to support@yunit.app.
What is yunit?
A browser extension that reads alongside you. On pages in the language you are learning, it picks a small handful of words you may not know yet and sets a tiny translation above each one, the way a student pencils a note in a margin. The sentence stays intact and reading stays the priority. Words you choose to keep return later, on a schedule the extension works out for each one.
Does yunit translate whole pages?
No. Browsers already do that well. yunit is for the opposite moment, when you want to stay inside the original language and be helped a little, in place. It adds small notes above a few words and leaves everything else exactly as the author wrote it.
Which browsers does it run in?
Chrome, Edge, and Firefox, on a computer. The install links are on the front page. With a free account, your words and settings can follow you between browsers.
Can I use it on my phone?
The extension runs on a computer for now. Phones are on the roadmap, Android first through Firefox for Android. The reading room on yunit.app works on a phone today, and on Android it can be added to your home screen. After that, share any page or passage to yunit, from your browser or any app, and it opens in the reading room with a few words translated.
Do I need an account?
No. Everything apart from live captions runs locally in your browser, signed out, free. A free account keeps your words and settings the same on every device you sign in on, backs up your vocabulary once a day, and includes thirty minutes of live captions a month. Signing in stays optional.
What does Premium add?
Fifteen hours a month of live translated captions on any tab with sound, sharper translations where standard machine translation misses the meaning, and a highlights library on yunit.app. Nine dollars a month or seventy-two a year, with thirty days money back, no questions asked. There is no trial that turns into a charge.
Which languages does it support?
You choose the language you are learning and your own, and the pair works in both directions. Most major languages are covered, and the full list is in the extension’s settings. If yours is missing, write to support@yunit.app and it moves up the list.
How does yunit choose which words to annotate?
It reads only the part of the page you can see, skips words you already know or have kept, and prefers words near the edge of your vocabulary, judged by how common they are in the language. You set the density yourself, from a single annotation per screen up to a dense reading aid, or off entirely for any site.
What happens to my data?
yunit is local first. Your vocabulary, review history, and settings live in your browser, and pages you visit are never tracked. When a word is translated, the extension first tries an on-device translator that runs entirely on your machine; if that is unavailable, only the text being translated goes to a translation service, with no identity attached. yunit also counts its own errors, anonymously, so a broken feature shows up quickly, and you can turn that off. The full notice is on the privacy page.
What are live translated captions?
Captions yunit writes as the audio plays, for a video, a lecture, a podcast or a stream that has no subtitles you can read. The spoken words become two lines, the original language above and yours beneath, following the speaker in real time. They sit in a bar at the bottom of the screen that follows you when you switch tabs, or on the video itself, and on YouTube a timestamped transcript builds beside the video. They run on Chrome, Edge and Firefox on a computer. Firefox listens to the page’s own player, so protected streaming services stay silent there. Any free signed-in account has thirty minutes a month, and Premium includes fifteen hours.
How many words do I know?
The two-minute test at yunit.app/test gives an estimate. It shows real words of the language mixed with a few made-up ones, and works out the number from the real words you recognise, discounted by any made-up ones you tick. With yunit installed, the number carries into the extension, which raises it as the words you keep settle.
How do kept words come back?
Mostly by appearing again in your ordinary reading, translated, a quiet second meeting. Now and then one returns as a small question mark that asks you to remember it before showing the answer, a few of these a day at most. The lexicon page also offers a short review session built from the very sentences you met each word in.
Is yunit finished?
No. yunit is in public beta, which means everything on this page works today and all of it is still changing. Features, limits, and prices may move while we learn what readers actually need. If something is rough or missing, write to support@yunit.app. A person reads every message.
The longer versions live on the privacy page and the pricing page, and yunit can be tried without installing anything in the reading room.
