What's new.

The first version anyone can install. The teacher is real and it talks back.

• Live AI voice teacher — hold the spacebar on any line to ask a question out loud and get a spoken answer.
• Spoken explanations: at the moments that matter, the show pauses and a tutor breaks the line down, then resumes.
• Dual subtitles and a click-to-save dictionary, layered onto your own Netflix.
• Your lesson library, with jump-back to the exact scene where you learned a phrase.
• Free and Pro plans, with secure Stripe checkout.
• 30+ languages, led by Spanish, French, German, Japanese, Korean and Mandarin.

• Streaming teacher audio — answers start playing while they're still being generated, so there's no awkward wait.
• A cadence control: choose how often the teacher interrupts — off, rarely, sometimes, or often.
• Refined the in-Netflix overlay so explanations sit cleanly over the player.
• New gold-on-black look across the extension and site.

• Sign in to save your words and lessons and sync them across devices.
• Per-user data with row-level security, plus a shared cache so popular shows load fast.
• Hosted backend so the extension works out of the box, no setup required.

Where it started: an offline tool that cut a film into bite-size language lessons.

• The original "lesson-cut" experiment that proved the idea — explain the line, then keep watching.
