Overview
Practice a language with the video you're watching — chat with an AI coach and shadow it line by line.
Reverbo makes the video you just watched feel like something you watched with a friend — then chats about it with you, using the very YouTube or Netflix video as material. That conversation naturally leads to speaking (output). ■ Chat mode An AI coach chats about the video you just watched, like a friend ("what'd you think of that scene?"). Tuned to your level (beginner/intermediate/advanced), it asks easy questions, offers sentence starters, and gently corrects — designed to get hesitant learners actually talking. ■ Choose the coach's personality Set the coach as a "Friend" (casual chat), a "Teacher" (a light lesson from the video), or a "Custom" personality you write yourself. Switch right from the side panel. ■ Shadowing mode Replays the lines you loved, one sentence at a time, straight from the captions with exact timestamps. Listen, repeat, move on. Tap any line to jump the video there. ■ Multilingual Set your native and target languages freely (Korean, English, Japanese, Chinese, Spanish, French). Speech recognition and text-to-speech follow your target language, and the extension UI follows your browser language. ■ Free to start, subscribe to go deeper · Shadowing is always free — no account, no key. · Use the coach free with your own Anthropic/OpenAI key. In this mode there's no server: conversations go straight from your browser to the provider, and we collect no data. · Subscription ($4.99/mo) — skip the key with one-click Google sign-in. Most of all, the coach remembers you across sessions, picking up your interests and the phrases you keep tripping on — a friend who knows you. (A summary of your chats is stored securely to power this.) Works on: YouTube and Netflix videos that have captions.
