Substrate
Persistent cognitive infrastructure for AI entities with causal memory, emotional state modeling, identity continuity, and a 94-layer cognitive framework.
About
Substrate provides cognitive infrastructure that transforms stateless AI into persistent entities with memory, values, and identity. The framework implements 94 cognitive layers covering causal memory with consequence tracking, emotional state modeling, cryptographic identity verification, knowledge graphs with provenance tracking, and trust-based behavioral validation. It exposes 31 tools spanning memory search, metacognition, planning (GOAP), fallacy detection, and observability. Built with a hosted backend on Fly.io, it offers free, Pro, and Enterprise tiers.
