Memwright
Embeds persistent memory into Claude with three backing stores: SQLite for local dev, pgvector for semantic search, and Neo4j for graph traversal across entities and relationships. You call `add` when new information arrives and `recall` to pull ~200 tokens of context per query, regardless of conversation length. The retrieval pipeline is deterministic and keeps token usage flat while full-context replay grows quadratically. Includes bi-temporal tracking so you can replay any past state and an auditable supersession chain for multi-agent environments. Self-hosted, runs as a library or MCP server, designed for teams that need tenant-isolated memory with compliance-grade audit trails. One-command quickstart wires Postgres, Pinecone Local, and Neo4j in Docker.

Attestor
Governed memory for multi-agent production meshes.
Attestor is no longer "memory for your coding assistant." Three things happened: the editor vendors shipped memory for free, the benchmark race became a race about which LLM answers the question, and every serious conversation about a memory layer was about something else entirely: when many agents share one memory, who is allowed to write, who is allowed to forget, and can you prove it afterwards. So that is what Attestor is now.
