Substrate

Persistent AI entity framework with causal memory, emotional state, and identity continuity.

SUBSTRATE gives AI entities real cognitive infrastructure — not just a prompt, but a living architecture with 94 cognitive layers including episodic memory, value systems, emotional affect, theory of mind, and narrative identity.

Built by Garmo Labs.
