Gotcha

Pre-watch briefings for foreign-language YouTube videos: vocabulary, phrases, and a summary before you press play.

Gotcha is a Chrome extension for language learners. Before each foreign-language YouTube video plays, Gotcha pulls the captions, sends them to an AI model, and produces a one-page learner briefing tailored to the video: • A short summary of what the video is about • Useful phrases with translations and usage notes • Vocabulary highlights, filtered against words you've already marked as "known" • Cultural and grammar notes when the video calls for them • A CEFR-style difficulty badge (A1 / A2 / B1 / B2 / C1) This means you walk into each video already knowing the hard parts, instead of getting lost five seconds in. Languages We're starting with German — Gotcha activates on YouTube videos that have German captions. More languages are on the roadmap; the architecture is multi-language-ready and we'll roll them out as we validate the briefing quality for each. How it works 1. Open any YouTube video with captions in a supported language. 2. Gotcha automatically pauses the video and shows the briefing as an overlay. 3. Click "Start video" when you're ready — the briefing stays accessible while you watch. 4. Mark phrases or words as "I know this" so future briefings skip them. Plans • Free — 3 briefings per day, up to 30-minute videos. • Pro (€5/mo or €50/yr) — 15 briefings per day, up to 90-minute videos. • Pro+ (€15/mo or €160/yr) — 60 briefings per day, up to 4-hour videos. Plus an anonymous mode that lets you try one briefing without signing in.
