How are people using AI to interact with YouTube videos?

I recently launched ChatYT - a small tool where you paste a YouTube link and it lets you:

• Chat with the video

• Get a structured summary

• Generate a PDF with key insights

The idea came from a simple problem. A lot of YouTube videos are 30-60 minutes long, but most of the time you just want the key information or a specific answer.

I'm curious how others deal with this.

• Do you use any AI tools to analyze YouTube videos?

• What features would make something like this actually useful for you?

Would love to hear how people solve this today.

If anyone wants to try it and share feedback:
