# MemoryLake

> Persistent AI memory infrastructure. One memory passport that travels across ChatGPT, Claude, Cursor, Copilot, Hermes, and every MCP-compatible AI — owned by the user, encrypted at rest, retrievable in milliseconds.

MemoryLake builds the memory layer that AI agents and applications use to retain user preferences, project context, conversation history, brand voice, codebase decisions, and domain knowledge between sessions. The platform exposes six memory types (Conversation, Fact, Skill, Background, Document, Episodic) accessible through REST and MCP.
