FAQ
How is it different from other translation extensions?
Every word you look up goes into your word book and lights up when you meet it again on another page, in a video or in a PDF, so you don’t have to look up the same word twice.
Does it work with videos?
Yes, with YouTube videos that have CC subtitles: click any word in the subtitles, show them in two languages or only the original, and jump back to that second when you review. Videos without CC subtitles aren't supported yet.
What are the limits on the free plan?
10 reviews, 100 word lookups and 20 sentence translations a day. Your word book shows the 50 most recent words; older ones stay saved in your browser and come back when you upgrade. Reviews cover your 50 most recent words; all your words are highlighted when they come up again. Compare Free and Pro
What is sent when I look up a word?
The word you selected and the sentence around it, so the meaning fits that sentence. The page address isn't sent, and PDFs are never uploaded. Privacy policy
Install it and go. No sign-up.
