Aibrify Translate
Everything on your screen, in two languages.

Why Aibrify Translate
Bilingual subtitles in 30 seconds
Install, open a video, done — no setup, no account.
Any web page, in two languages
Alt+T for the whole page, hold Alt to translate one paragraph, select text for a bubble — and Alt+I turns what you type into the language you need.
PDFs and documents, never uploaded
Drop a PDF, Word, PowerPoint, Excel or Markdown file into the built-in viewer — original on the left, translation on the right, scrolling together. No watermark, no page limit, no account. Scanned pages are named as scanned instead of faked.
Three engines, all free
Chrome's on-device translator keeps the text on your computer; a free public engine covers the pairs it doesn't; or bring your own DeepL, Google, OpenAI, DeepSeek or Gemini key — the call goes straight from your browser to the provider you picked.
Hover to look up, auto-pause while you read
Words from videos and pages go to one vocabulary book with no cap from us — offline, exportable, and never behind a paywall.
Built to stay working
Remote hot-fixes when sites change, a public status page, and outage notices in your own language.
What works today, and what comes next
Bilingual subtitles on YouTube, bilingual web pages, PDF and document reading in the built-in viewer, selection and input-box translation, and the vocabulary book.
A Pro tier with an AI translation track, sentence-by-sentence explanations and spaced-repetition review; EPUB reading; and live captions for online meetings. Everything shipped above stays in the free core.
Questions
- YouTube. Subtitles come from the track the player already loads, so there is no setup and no account.
