PreviousNext

Fetches a video's metadata and transcript, then answers questions with clickable timestamp citations.

Summary

The Chat with YouTube Agent answers questions about a video using its transcript. It pulls the video's metadata and full transcript, then summarizes, answers follow-ups, and generates chapter timestamps — each citation a clickable link straight to that moment. Reach for it to skim long talks, lectures, or podcasts without watching end to end.

Installation

$ pnpm dlx shadcn@latest add @agentcn/eve/chat-with-youtube

Customization

  • Reliable fetching. Metadata and transcripts are pulled through the Bright Data Web Unlocker, which handles YouTube at scale with no rate limits or blocks. Set BRIGHTDATA_API_KEY (and optionally BRIGHTDATA_UNLOCKER_ZONE).
  • Add chapters export. Add a tool that writes the chapter list back as a YouTube description or VTT file.
  • Handle missing transcripts. Fall back to an STT service when a video has no captions.
  • Swap metadata source. Use the YouTube Data API for richer metadata.
  • Swap the model. Edit agent/agent.ts.
