My friend Milla Jovovich and I spent months creating an AI memory system with Claude. It just posted a perfect score on the standard benchmark - beating every product in the space, free or paid.
It's called MemPalace, and it works nothing like anything else out there.
Instead of sending your data to a background agent in the cloud, it mines your conversations locally and organizes them into a palace - a structured architecture with wings, halls, and rooms that mirrors how human memory actually works.
Here is what that gets you:
β Your AI knows who you are before you type a single word - family, projects, preferences, loaded in ~120 tokens
β Palace architecture organizes memories by domain and type - not a flat list of facts, a navigable structure
β Semantic search across months of conversations finds the answer in position 1 or 2
β AAAK compression fits your entire life context into 120 tokens - 30x lossless compression any LLM reads natively
β Contradiction detection catches wrong names, wrong pronouns, wrong ages before you ever see them
The benchmarks:
100% recall on LongMemEval β first perfect score ever recorded. 500/500 questions. Every question type at 100%.
92.9% on ConvoMem β more than 2x Mem0's score.
100% on LoCoMo β every multi-hop reasoning category, including temporal inference which stumps most systems.
No API key. No cloud. No subscription. One dependency. Runs on your machine. Your memories never leave.
