Your Kindle collects the words you looked up. Book2Deck turns them into Anki cards.
Connect the Kindle over USB, review the words the device saved while you were reading, and export the ones you want as an Anki-compatible CSV file.
What this means in practice
- Nothing to install: a desktop Chromium browser is enough.
- No account and no sign-up.
- Your vocabulary is parsed inside the browser and is never uploaded.
- The Kindle is only ever read, never modified.
