Ask questions, get answers, right from video transcript

Daneel now understands YouTube videos.

When you open any video on YouTube, Daneel automatically extracts the full transcript and makes it available as context for your conversation.

No extra clicks, no copy-pasting, just open the video and start asking.

How it works

Navigate to any YouTube video with captions available. Daneel detects the video, pulls the transcript directly from YouTube's player API, and processes it into a clean, timestamped document — complete with the video title, channel name, duration, and language.

From there, you can ask anything in Page Q&A mode:

  • "Summarize this video in three bullet points"
  • "What does the speaker say about pricing at around the 12-minute mark?"
  • "List all the tools mentioned in this tutorial"
  • "Explain the main argument in simpler terms"

The transcript is formatted with timestamps, so answers can point you to the exact moment in the video.

Every language YouTube supports

Daneel works with all caption tracks YouTube provides — manual and auto-generated, in any language. It automatically selects the best available track: manual captions first, then auto-generated, with a preference for your browser's language.

The output clearly labels whether captions are manual or auto-generated, so you always know what you're working with.

No third parties involved

The transcript flows directly from YouTube's API to your local extension. No external transcription services, no data leaving your machine beyond the standard YouTube request. The same privacy model you expect from Daneel applies here — your questions and the transcript stay local to your browser.

Works with YouTube's SPA navigation

YouTube uses client-side routing — clicking from video to video doesn't trigger a full page reload. Daneel handles this correctly, detecting navigation events and extracting a fresh transcript each time you switch videos. No need to refresh the page.

It works with every AI backend: WebGPU, Ollama, Gemini Nano, or Claude.
