Yes, that Milla Jovovich. Leeloo from The Fifth Element. She and developer Ben Sigman built an AI memory system called MemPalace, pushed it to GitHub three days ago, and it already has over 19,000 stars.
It's not a vanity project. The thing actually works.
What it does
MemPalace stores your AI conversations locally and makes them searchable. Instead of letting Claude or ChatGPT conversations vanish after each session, it keeps everything verbatim and organizes it using a structure borrowed from the ancient Greek memory palace technique: wings for people and projects, rooms for specific topics, and so on.
Jovovich landed on the concept after months of frustration with losing context across AI sessions.
Why small teams should care
It runs entirely on your machine. No API keys, no cloud, no monthly fees. Compare that to Mem0 at $19-249/month or Zep at $25/month and up. For a 10-person nonprofit or a small municipal office, free matters.
It also performs. MemPalace scored 96.6% on LongMemEval in raw mode, the highest published score for any free memory system. It works with Claude, ChatGPT, and Cursor through MCP. There's also a knowledge graph that tracks when facts start and stop being true, which is a neat touch for teams juggling lots of changing context.
The backstory
Jovovich designed the core architecture. Sigman built it. MIT license. Zero to 19k+ stars in 72 hours.
We don't often get to write about a multipass-wielding action star shipping Python to GitHub. But the project doesn't need the celebrity angle, it just happens to come with one. If your team uses Claude Code, ChatGPT, or Cursor and you're tired of re-explaining context every session, MemPalace is worth 20 minutes to set up.
