SUBSTRATE

A persistent entity framework that gives AI assistants cognitive infrastructure across 94 layers including episodic memory, emotional state, values, and narrative identity. Connects via API key from Garmo Labs and exposes 31 tools split across memory operations (search, knowledge graph queries, hybrid search), cognition (theory of mind, metacognition, personality), emotion tracking and traces, planning with GOAP, and reasoning (fallacy detection, causal reasoning, isomorphism detection). Each entity maintains continuity across conversations with provenance tracking and identity verification. Reach for this when you need an AI that remembers context, develops coherent personality over time, and reasons about its own mental states rather than starting fresh each session. Free tier includes one entity with 1,000 API calls monthly.
