I built a Chrome extension that lets you chat with the transcript of any YouTube video. Instead of sitting through like a 2 hour video, you can just ask a question and get an instant answer.

The Problem:

I built it mainly for myself: I often watch long-form videos like lectures or tutorials on YouTube, and I want a fast way to extract the information I need without scrubbing through timestamps or rewatching sections. For example, I recently used it with a 3.5-hour lecture and got the exact answers to my questions in seconds.

Another example is that nowadays YouTubers often create videos around one or two key ideas, and I can now figure out whether a video is worth watching by asking what those key ideas are in advance.

How it works:

1. The extension gets the video transcript. 2. An AI model summarises it, and makes the content ready for chat 3. You can switch between chat mode and auto-generated summaries depending on how deep you want to go.

What’s different:

1. It’s not just a summarizer: you can interact with the content in real time and ask follow-up questions 2. It saves a huge amount of time if you’re studying or just watching a long video and curious about a specific part of it.

Feedback: If you find it useful, I’d really appreciate your feedback on your experience with it and what you’d improve.

Thanks!
