GitHub·high signal

MemPalace, launched April 5, 2026, gives LLMs persistent cross-session memory using a spatial hierarchy (wings, halls, rooms) inspired by the Method of Loci. It scored 96.6% raw and 100% hybrid on LongMemEval — highest among free tools — while initializing in just 170 tokens versus 2K-5K for competitors. Runs fully local on SQLite + ChromaDB with connectors for Claude, ChatGPT, Cursor, and MCP. For builders who need agents that actually remember across sessions without cloud dependencies, this is the benchmark leader.
