Palimpsest

Colours Russian words on any page by how well you know them, with Palimpsest's word popup, flashcards and a YouTube captions panel.

For English speakers learning Russian: see the Russian you actually know, on every page you read. Most language apps track what you did inside the app. Palimpsest models what you know. Every Russian word has a score, and every encounter is evidence: a word you read past without looking it up, one you had to look up, a flashcard you remembered or forgot, a line of a video you heard. This extension brings the rest of the web into that picture, and shows the picture back to you wherever you read. ON ANY RUSSIAN PAGE • Words are coloured by how well you know them: the darker the colour, the newer the word. Words you know stay plain. • Click a word for a definition in Russian, written with words you already know, plus its English meanings, its inflections and your own score, which you can change. Reject a word, or flag it for a future flashcard deck. • Flashcards that are due are marked where the word appears. Click, answer, and the review counts, as in the app. • Save any Russian page to your Palimpsest library with one click. ON YOUTUBE • A captions panel beside the video shows the Russian captions, coloured and clickable, and follows the video. It pauses the video while you look a word up. • The lines you actually heard count towards your scores. Save the video, captions and all, to study it in the app. YOUR READING COUNTS Words you read or hear without looking them up count towards your scores, as reading in the app does. That is how Palimpsest learns what you know from what you do, rather than from what you tell it. You can switch this off in Palimpsest Settings. PRIVATE BY DESIGN The extension reads pages on your computer. It stops at any page that is not in Russian. It never sends us a page's address or text unless you press Save. It sends Russian words, not pages, in batches mixed across pages. It contains no analytics and no advertising.
