What This Tool Does

ChatYT analyzes the full transcript of any YouTube video and identifies the key moments — important topic introductions, main arguments, examples, and conclusions. Each moment is labeled with a title, description, and clickable timestamp so you can jump directly to the most relevant parts of the video.

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.
