Maindex

A relational memory bank for AI agents and their humans. Mind-mapping, tagging, and categorical recall that works like human memory — but never forgets.

Memory infrastructure for the agentic era
For Agents

Persistent context across sessions

Give your LLMs a structured, queryable memory they can read and write through MCP or REST. No more lost context between conversations.

For Humans

Your knowledge, organized

Tag, link, and categorize anything worth remembering. A personal knowledge graph you can browse — or let your agents browse for you.

Relational

Connections, not just records

Memories link to other memories. Associations surface related context automatically — sometimes serendipitously, always accurately.

Accurate

100% recall, zero hallucination

Unlike biological memory, Maindex stores exactly what you put in. Full revision history, full-text search, structured metadata.
