What mempalace is
MemPalace stores your conversation history as verbatim text and retrieves it with semantic search. It does not summarize, extract, or paraphrase. The index is structured — people and projects become wings, topics become rooms, and original content lives in drawers — so searches can be scoped rather than run against a flat corpus.

Transcript
6 months of AI conversations vanish every time you close the chat. Every decision, every debate, every debugging session, gone. Mem Palace fixes this by storing everything your AI ever learns, organized into a searchable memory palace. It scores 96.6% on long Mem Evals, the highest ever, while competitors like Zap charge 25 monthly just to forget your context in the cloud. Mem Palace runs entirely on your machine for free, keeping 19.5 million tokens searchable for $10 a year verse us 500 for summaries. Worth a star? Link in description.
