Runnable cognitive frameworks distilled from six historical figures — each an AI skill with labeled quote provenance, era-anchored reasoning, and public/private expression registers.

We build AI that simulates how the world works and how it became what it is — history as it happened, personal lives as they were lived, and the timelines that could have been.
NeuroForest is a new AI lab building tools that simulate the workings and evolution of the world — history as it happened, personal lives as they were lived, and the timelines that could have been.
Read our storyWe simulate as closely as the record allows — and mark clearly when it doesn't.
Every claim is traced to a source; every inference is labeled by kind.
Our output holds up to historians — not just to first-impression readers.
Each project is a different way of simulating the world — a different grain, a different source material, a different kind of fidelity. We start with how people thought.

A simulator of personal histories, plus a larger project still under wraps.
Why this isn't "AI roleplay." How we handle provenance, era, and anachronism. What's open source. How to try it. A few openers are on the right.
