What happens to the knowledge inside an organisation when the people who carry it leave?
Not the documents. Not the Notion pages or shared drives.
The actual intelligence. The reasoning behind decisions. The pattern recognition that took years to build. The understanding of *why* something was tried, *why* it failed, *what* was learned.
In almost every organisation, that intelligence lives inside individual human minds.
And when someone leaves — it disappears with them.
This is the problem
@DrazenKapusta and I have been working on.
Today, we're publishing something we're genuinely proud of.
🧠 THE SHARED BRAIN: When Second Brains Start Thinking Together
With
#TheCurator v3.0.0-beta, a personal second brain — a living neural network of markdown files that compounds knowledge over time — can now be shared.
Not as a static library.
Not as a document archive.
As a live, compounding collective wiki that every contributor can query with frontier AI models, navigate as a knowledge graph, and build on — without ever surrendering control of their private data.
Here's what makes it different:
✦ You keep everything private. Only one chosen domain gets contributed.
✦ Your local LLM synthesises your changes before they leave your machine.
✦ The collective wiki resolves contradictions, attributes every fact, and compounds with every push.
✦ Every contributor pulls the result back locally — queryable via Claude, browsable in Obsidian.
✦ Zero vendor lock-in. GitHub a local app. That's the entire stack.
The use cases are wide open:
→ Research teams whose combined reading is too vast for any one person
→ MBA cohorts building a collective knowledge graph across a full semester
→ Engineering teams where critical decisions live only in senior minds
→ Consulting firms whose accumulated insight walks out the door with every departure
This feature was shaped by the Beautiful Mind thesis — our research on federated cognitive architecture and collective intelligence submitted to the EIC Pathfinder Challenge — co-developed with
@DrazenKapusta at
@COTRUGLI Business School.
The second brain was always the beginning.
The Shared Brain is where it becomes something else entirely.
