The extension runs on every page. You learn by reading what you already read.
Start with the 500 most common words. As you learn them, harder words appear. Five tiers from A1 to C1.
Words are replaced inline on pages you already visit. News, Wikipedia, Reddit — it all becomes practice.
Seen a word 10 times but never clicked “known”? The extension notices and helps you focus on it.
No drills, no streaks, no guilt. Just real context. Hover any word to see the original. Click when you know it.
The extension is free forever. Sync is for people who browse on multiple devices.
We built this the way we’d want it built for ourselves.
No analytics, no telemetry, no fingerprinting. The extension has zero tracking code.
Your browsing data never leaves your browser. No URLs, no page content, no history — nothing.
The server stores an opaque blob it can’t read. Your license key + a PIN you choose encrypt everything client-side.
Pay → get a random license key → paste it in. No email, no login, no password. The key is your identity.
