AI Agent for YouTube

Summarize any YouTube video, explain it with analogies you pick, or get expert commentary. Free on-device AI, no setup.

Get the point of a YouTube video without sitting through all of it. AI Agent for YouTube adds a panel next to the video that reads the video's captions and lets you summarize it, have it explained in terms you already know, or hear what an expert would say about it. FREE, NO SETUP Works the moment you install it. It uses Chrome's built-in AI, which runs on your own computer: no account, no API key, no cost, and the video's content never leaves your device. (The first time, Chrome downloads its AI model once. Needs a reasonably recent computer.) THREE WAYS TO USE IT • Summarize – A short TL;DR, then the key points in order, then notable details like numbers, names and recommendations. Tell it what you care about ("just the pricing part") and it focuses there. • Explain – Have the video explained through analogies from a world you know. Type "I'm a rock climber" and each idea comes back as a climbing analogy, with a note on where the analogy stops working. • Ask an expert – Pick a point of view, like a vocal coach, a developer or a financial analyst, and get the commentary that person would give, pointing to specific moments. WHY INSTALL IT • Clickable timestamps – Every timestamp in an answer jumps the video to that moment, so you can check any claim yourself. • Grounded in the video – Answers come from the video's captions, not guesswork. • Follow-up questions – Keep the conversation going after the first answer. • Saved per video – Your chat with each video is still there when you come back. • Handles long and dubbed videos – Long videos are condensed first; dubbed videos use the best caption track available.
