MemPalace claims 96.6% R@5 on LongMemEval with zero API calls, and warns of malware-distributing impostor domains.

MemPalace/mempalace (57,888 stars) stores conversation history as verbatim text and retrieves with semantic search, explicitly refusing to summarize, extract, or paraphrase. The index is structured into wings (people/projects), rooms (topics), and drawers (original content) so searches can be scoped rather than run flat. Pluggable backend, currently defaulting to ChromaDB. The repo now leads with a caution that impostor sites on .tech, .net, and other .com variants may distribute malware. That's a new failure mode for high-star AI infrastructure and worth checking before you curl | sh anything.
