An advisor brain,
built from YouTube.

Brilliant ideas,
stuck in hours of video.

I'm a big fan of Rory Sutherland and Chris Do. They put genuinely valuable thinking on YouTube, for free, but it's scattered across dozens of hours of long interviews. To actually use it, I kept going back and rewatching the same videos for the same context. Two things became obvious:

One, it's hard to merge all that knowledge into a single strategy or thought. Two, those ideas get far more powerful when you can use them together, alongside other smart ideas. And the way to combine them is to put them in one brain and brainstorm from it.

I hired their brain
from their content.

This was the first knowledge graph I ever built, a case study to test the idea. I transcribed the videos I wanted to keep, and using the Neo4j MCP connector I processed them into a Neo4j digital brain that holds all that context. Now I talk to it through the same connector: I ask questions, brainstorm, and generate practical ideas, and I audit my own work against it. I've run my own website through the "Chris Do brain" to find which best practices I'd missed.

Used this way, the brain becomes an authenticity audit. Before a piece of content goes out, the agent checks it against a consistent representation of the brand and flags where it drifts. The real unlock was making tacit knowledge visible: taking what those thinkers do on instinct, and what I do on instinct, and turning it into something explicit I can question and reuse. Brand work is iterative, so the brain keeps earning its place.

For Chris Do alone I used 30 videos, most over an hour, interviews, which I find the most compelling content on the internet. Then I did the same with Rory Sutherland's ideas and experiments in consumer behaviour. It's like hiring their brain from their public content: not creative, but a sharp simulator of how they think.

The build that
started 3nuggets.

This experiment is what convinced me: the value isn't the videos, it's being able to think alongside them, on demand.
