What it does
MemPalace saves your conversation history word for word and lets an AI assistant search it later. It does not summarise or rewrite what was said.
It organises memories like a building: people and projects are "wings", topics are "rooms" and the original text sits in "drawers". This lets searches focus on one area instead of everything at once.
Its makers say nothing leaves your machine unless you choose to share it. It connects to AI coding assistants such as Claude Code through MCP, a standard way to plug tools into AI apps, and can also run as a shared hub.
Who it's for
