Maindex

The source of truth for your AI agents. A cross-platform memory layer with full provenance, typed structure, and scoped access, so every agent you use remembers what matters.

Memory infrastructure for the agentic era
For Agents

A source of truth agents can write to safely

Give your LLMs a shared memory layer they can read and write through MCP or REST. Every change is tracked with revision history and supersede chains. Agents can automate memory hygiene without rewriting the source of truth.

For Humans

Your knowledge, structured and linked

Tag, link, and categorize anything worth remembering. Typed relationships, canon status, and confidence scores turn loose notes into a knowledge graph you can trust and your agents can reason over.

Portable

Write once, recall anywhere

One memory layer, every AI tool. Cursor, Claude, ChatGPT, Gemini, Windsurf — connect with a single OAuth URL and your full graph follows you. No vendor lock-in, no re-syncing, no per-tool plugins.

Accurate

100% recall, zero hallucination

Maindex stores exactly what you put in and lets you trace any fact back to its origin. Revision history, typed links, and structured metadata — not a probabilistic guess.

Observable

Observability for agent memory

See what your agents remember and how they use it. Activity heatmaps, usage analytics, and an interactive knowledge graph explorer — because a memory layer you can't inspect isn't infrastructure.

Secure

Locked collections, tenant isolation

Lock sensitive collections behind a passphrase so they stay hidden until you unlock them. An additional authentication layer prevents agents from bypassing the lock. Every tenant is fully isolated. Encryption at rest and in transit.
