MemPalace
Solves the biggest gap in Claude workflows: forgetting context between sessions. The spatial metaphor makes memory organization intuitive.
Open-source AI memory system that gives Claude persistent cross-session memory. Stores conversations in a hierarchical memory palace structure (wings, rooms, halls, closets, drawers). Uses ChromaDB for vector search and SQLite for a knowledge graph. 19 MCP tools. Runs entirely locally.
- Store and retrieve project context across multiple sessions
- Search past conversations and decisions using natural language
- Organize persistent memory in a structured hierarchy
Solves the biggest gap in Claude workflows: forgetting context between sessions. The spatial metaphor makes memory organization intuitive. However, the project is only days old with documented gaps between marketing claims and actual code capabilities.
Teams running long-running Claude projects who need context persistence across sessions. Wait for the project to mature before production use — benchmark claims are overstated and security hardening is still in progress.
