Myco vs Mem0: Deterministic Team Memory vs App-Level Memory

Mem0 is strong for app-level memory primitives. Myco is built for shared organizational memory across many agents and workflows.

Bottom line

If you need a single memory layer for many agents, strict provenance, and workspace-scoped governance, Myco is the better fit.

FAQ

How is Myco different from a memory store like Mem0 or MemPalace?

Mem0 and MemPalace are retrieval/memory stores. Myco adds a trust layer on top: a knowledge graph, provenance on every fact (brain_why), compounding confidence, and supersession when facts are contradicted, plus per-object permissions, all self-hosted on your own Postgres. On metrics, we report numbers that reproduce on the full set: end-to-end QA accuracy of 73.6% on the complete 500-question LongMemEval oracle subset, and keyless recall@5 of 89.2% (rising to 91.6% with the recency reranker) on the full longmemeval_s set, each with a one-command reproduction, no paid reranker required.

Is Mem0 bad for teams?

No. Mem0 can be useful for application memory. Myco is optimized for cross-agent, cross-workflow organizational memory.

Can Myco be self-hosted?

Yes, self-hosting is the default. Clone the repo and run docker compose up -d; the Apache-2.0 core runs on your own Postgres. Managed cloud is waitlist-only at mycobrain.dev, not generally available.
