FanFan Cards
More than a translation you forget five minutes later. FanFan remembers the sentence where you met a word, keeping its meaning, source, and review history together.

How it works
One path from getting stuck to making it stick.
02 · Save it with its source
Each card keeps the original sentence, page, date, and model source. When you review it later, you see more than an isolated translation.
03 · See it again when it matters
A four-level confidence rating drives spaced review. The dashboard keeps saved cards, reviews due, study streaks, and familiarity levels visible.
04 · Keep ownership of your data
Your data stays in your browser by default and can be exported as JSON or CSV. If you choose, you can sync it to a private repository in your own GitHub account.
Privacy by design
Know where your data goes before you install.
The extension reads selected text, nearby context, the page title, and URL only when you ask it to explain or translate. Once you configure a model, that content goes directly to the provider you choose. There is no developer-operated relay server and no advertising, analytics, or tracking service.
