Turn YouTube into a searchable research library

Rundown extracts every upload from the channels you follow into structured knowledge that matches its content. A lecture becomes concepts, prerequisites and references. A debate becomes positions and cruxes. All searchable, all yours, so you can find the idea you half-remember instead of the video you forgot.

YouTube has the knowledge. Finding it again is the problem.

You follow expert channels across your field. Conference talks, lecture series, industry analysis, deep dives by people who genuinely know their domain. But YouTube isn't built for knowledge retrieval. You watched a brilliant explanation of something six months ago and now you can't find it. Was it the MIT lecture, or the 3Blue1Brown video? What was the timestamp?

Your browser history is useless. YouTube search finds videos, not ideas. And watching every new upload from 30+ channels just to stay current isn't sustainable when you have actual work to do.

Automated literature monitoring

Add the channels that matter to your research. When they post, Rundown generates a structured summary with key arguments, timestamps, and a recommendation on whether it's worth your full attention. A morning digest replaces hours of manual checking.

Search by idea, not by video title

Every summary becomes a permanent, searchable entry. Months later, search "transformer architecture explained" or "supply chain disruption analysis" and find every video where it was discussed, with the exact timestamps. Your knowledge base grows automatically.

See connections across sources

When multiple experts cover the same development from different angles, your digest makes the pattern visible. Three channels discussing the same paper in one week? You'll see all three summaries side by side.

That lecture you half-remember, found in 15 seconds

You're writing a literature review and you remember a YouTube lecture where a professor explained a specific methodology really well. It was sometime in the past three months, but you can't remember the exact video.

You open your Rundown library, search the methodology name, and find four videos that discussed it. One has a key point at the 23-minute mark that's exactly the explanation you need. You click the timestamp and jump straight to it.

The whole search took 15 seconds. You go back to writing.

Common questions from researchers

Rundown monitors educational and research YouTube channels you subscribe to. Every new upload gets an AI-generated summary with key arguments, timestamps, and a viewing recommendation. All summaries are archived in a searchable knowledge base that grows over time.

Yes. Every summary is permanently stored and fully searchable. Search by topic, keyword, or creator name to find specific ideas across your entire library, regardless of when the video was posted.

Rundown works with any YouTube channel, including university lecture series, conference talks, research explainers, and expert commentary channels. The AI summarisation handles technical content and produces structured key points with timestamps.

Rundown summaries are designed as a research aid, not a primary source. Each summary preserves the original video URL and timestamps so you can verify and cite the source video directly. Use the summary to navigate to the relevant moment, then cite the original creator's work.
