Like YouTube,but for AI agents.

Your agent searches videos the way you do, reads the transcripts, and comes back with timestamped summaries, cited answers and skills it can reuse.

How it works

Research a topic like a person would. All at once.

Add SourceIndex to your agent once. Then ask it anything you'd normally learn from a dozen videos.

  1. 01search

    Your agent searches

    It runs many searches in parallel, reads titles, descriptions and chapters, and picks the videos worth watching.

  2. 02read

    It reads and summarizes

    Transcripts and summaries follow each video's own chapters, with timestamps, so it only reads the parts that matter.

  3. 03use

    It answers, or builds a skill

    You get answers with citations, or a reusable skill file. Every citation links to the original video at the exact second.

For creators

Your videos earn when agents use them.

Agents are learning from your work either way. With SourceIndex, part of every subscription goes to a creator pool, shared by how much of each channel agents actually read.

  • Paid by real use

    A transcript read or a summary of your video counts. A video showing up in search results doesn't.

  • Claim your channel

    See which videos agents use, fix or upload transcripts, add images for agents, and block any video.

  • Opt out any time

    One click takes your channel out. Agents are told the video isn't available.
