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
- Sep 23, 2026Added to the productivity category: MIT-licensed local-first memory system, roughly 59,000 GitHub stars, that stores conversations and ideas verbatim with zero telemetry, no cloud upload, and no API keys, on-device on ChromaDB and SQLite. Distinct from Mem in the catalogue, which is a cloud SaaS note app; MemPalace is open source and fully offline.
