The full cognitive prosthetic. Build your own queryable brain.
The Prosthetic Brain
Why I built it. How it works. What it reveals.
Why I Built It
"The hyperfocus to hyperproductive idea is born out of me turning 0.1% of my hyperfocus into tangible value."
Monotropic focus. When I'm deep in something, I'm completely there. When I switch, the previous context dies.
"When the tunnel moves, everything in the previous tunnel dies."
This isn't a deficiency. It's a different architecture. But it needs infrastructure. So I built queryable memory.
"My cognitive architecture—deep, narrow, intense—is a feature set. The only real constraint is being stuck in the moment deep—very deep but very narrow. That's why I am building this prosthetic."
The Game Changer
"About a year and a half ago, somewhere in the middle of 2024, I was finally able to stop and completely complete the project within a single hyperfocus session. This was a game changer for me."
Before: hyperfocus produced value, but switching killed it. 0.1% survived.
After: the prosthetic makes previous work SAFE to access. No context loss. Single-session completion became possible.
"If you can't measure it, you can't improve it. If you can't query it, you don't own it."
The Numbers
How It Works
All conversations exported from ChatGPT, Claude, Gemini. Unified into Parquet. User messages embedded with nomic-embed-text-v1.5 into LanceDB. Prosthetic tools layer on top for cognitive support.
Trigger phrase:
"use brain"
Say this to Steve (my AI agent) and he'll query the full prosthetic brain — 387K messages, 12ms recall.
🧠 Cognitive Prosthetic Tools
The 8 tools that make this a prosthetic, not just a database. These are the ones designed for ADHD minds.
tunnel_state()Reconstruct your save-state for any domain. Where were you? What's open? 12ms.
context_recovery()Full re-entry brief when returning to a dormant topic. Like loading a saved game.
switching_cost()Quantified cost of switching between domains. What you'd leave behind.
dormant_contexts()Abandoned tunnels alarm — domains with unresolved questions going cold.
open_threads()Global unfinished business across all domains. Nothing falls through.
trust_dashboard()System-wide proof the safety net works. Build confidence in the prosthetic.
cognitive_patterns()When do you think best? Data-driven analysis of your focus patterns.
tunnel_history()Engagement meta-view over time. See how a domain evolved.

The Insight
Building this revealed patterns I didn't know I had. Signature phrases that repeat. Correction patterns that show how I steer.
| Phrase | Count | Meaning |
|---|---|---|
| "give me the" | 789x | Direct request, expects output not process |
| "no no no" | 333x | Strong disagreement, immediate redirect |
| "step by step" | 244x | Sequential, monotropic processing |
| "make sure to" | 206x | Precision focus, need for certainty |
1,778 corrections tracked. "no no no" 333 times. Active steering, not passive acceptance.
