🦙 Live on Product Hunt

Stop re-explaining yourself to every new AI. MindVault is your permanent memory layer.

One 15-minute interview builds a structured knowledge graph. Every AI you ever talk to can query it.

Why now

MCP is becoming the standard.

Model Context Protocol is the wire format every AI tool wants to speak. MindVault sits behind it — queryable from anything MCP-compatible.

Memory is now a first-class AI concern.

Claude, ChatGPT, and Gemini are all shipping long-term memory features. The external brain wins on portability and user control.

You're tired of repeating yourself.

Every new chat starts from zero. "I work on X, live in Y, prefer Z." A persistent, queryable brain saves those words.
