The honest answers.

Is this just an AI summary?

No. Every claim is anchored to the source, the timestamp, and a screenshot, and the pipeline is built to avoid inventing numbers. The difference is "an AI summarized it" versus "here is the claim and the exact frame it came from." You can act on the second one.

How is this different from using ChatGPT on a transcript?

Transcripts miss the screen. Half the value in a build tutorial is on-screen: the file tree, the config, the dashboard, the exact prompt. We capture every frame, so the copy-paste config isn't lost. And we run it every week on your channels, governed and consistent, so nothing slips.

What channels can you cover?

Any public video channel. We're proven on the AI-builder and AI-automation niche specifically, so if you follow Claude Code, AI agents, or automation-agency creators, you're exactly who this was built for.

What's the free first brief?

Pick one channel. We distill its recent uploads and send you a real brief at no cost and no card. If it saves you an evening of watching, you'll know.
