Gotcha

About

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.

  Privacy
  We collect: your Google email when you sign in, your Stripe
  customer record when you subscribe, and the video IDs of briefings
  you request. We don't sell or share data, don't use tracking
  cookies, and you can request deletion at [email protected].
