Just watched something? Talk it over, like with a friend.
After a YouTube or Netflix video, Reverbo strikes up a chat about it — "so what'd you think of that scene?" Talk along, and you're suddenly speaking the language.

You loved it — but there's no one to talk to about it
Captions and translation just help you follow along.
It becomes the friend you talk about it with.
Two ways in
Chat — it talks to you like a friend
Reverbo opens up about the scene you just watched: "which part got you?" It asks at your level, hands you sentence starters when you stall, and glides past mistakes like a friend would. Low pressure — you just keep talking.
Shadowing — replay the lines you loved, out loud
Hear the lines you liked again, one sentence at a time. Captions often break mid-sentence — we put them back together the way they're spoken. Turn on sound and meaning for scripts you can't read yet. Listen, repeat, move on.

Shadowing and terminal translation are always free. Your own key covers the rest. Subscribe and the coach remembers you — and your terminal prompts get kept.

- Sound, meaning, and coach — your own API key (Anthropic·OpenAI)
- No account · zero chat data
- A coach that remembers — the more you talk, the more it knows you
- One-click Google sign-in, no key
- A friend who knows your interests and where you get stuck
- Your terminal prompts get kept, to read back later
Use your own key — your chat never touches our server
This is the free mode, where you bring your own API key. The subscription mode is spelled out honestly in the last line.
- Use the coach with your own Anthropic or OpenAI key — pay them directly, no markup
- No server — chat goes straight from your browser to Anthropic or OpenAI, so in this mode the developer's server receives neither your chat nor your captions
- Shadowing is free, no key and no account
- Subscription mode signs in without a key and stores only a summary of your chats, securely, so the coach can remember you (see Privacy Policy).
Anywhere on YouTube and Netflix, as long as it has captions
Use whatever you were already watching. Nothing to set up.
