Skip to the parts that matter
Long videos contain great content, but finding the right moments takes time. ChatYT solves this by automatically detecting key moments in any YouTube video. Instead of scrubbing through a 2-hour lecture, you see a curated list of the most important timestamps. You can then chat with the video to ask questions about any moment, or get a full AI summary.
How AI detects key moments
1. Paste a YouTube link
Copy any YouTube video URL and paste it into ChatYT. The transcript is extracted automatically.
2. AI finds highlights
The AI reads the transcript, identifies topic shifts, key arguments, and noteworthy segments.
3. Click to seek
Click any key moment to jump directly to that timestamp in the video player.
