Why Your AI Forgets Everything — and How MemPalace Fixes It

Every AI conversation starts from scratch. Close a ChatGPT or Claude session, and everything discussed — decisions, reasoning, context — vanishes. This is the problem MemPalace solves. ## What is MemPalace? MemPalace is an open-source AI memory system created by Milla Jovovich and Ben Sigman. It gives any LLM persistent, cross-session memory that runs entirely on your local machine. Install: pip install mempalace ## The Key Insight Most AI memory systems (Mem0, Zep, Supermemory) use an LLM to extract "key facts" and throw away the rest. This is lossy compression — the AI decides what matters, and everything else is gone forever. MemPalace takes the opposite approach: store everything verbatim, then make it findable. Nothing is lost. When you need context from 3 months ago, it's there — the full reasoning, alternatives considered, and nuance. ## Benchmarks | System | LongMemEval R@5 | Cost | Local | |--------|----------------|------|-------| | MemPalace (hybrid) | 100% | Free | Yes | |
