MemPalace

By MemPalace

MIT-licensed local-first memory system, around 59,000 GitHub stars, that stores conversations and ideas verbatim and organizes them hierarchically using the method-of-loci technique adapted for machines, with zero telemetry, no cloud upload, and no API keys required; runs entirely on-device on ChromaDB and SQLite, installed with pip.

Best for

  • keeping a searchable, private record of AI conversations and decisions
  • persistent memory for a personal assistant with no cloud dependency
  • retrieving past context verbatim instead of a rewritten summary
  • a memory layer that works fully offline
  • avoiding recurring API costs for memory storage
