Why we built Maindex
AI systems are great for reasoning, but they make terrible databases. In a world where LLM context and attention are highly valuable resources, we needed a stable, long-term memory system built for AIs and their humans.
Maindex exists to make memory a reliable primitive for agentic software, not an afterthought.
We needed data portability across every platform to free our important data and make it useful on every platform we use.
We are building a durable memory layer that feels natural to developers, useful to humans, and dependable in production.
What Maindex is
Maindex is a relational memory platform for agents and applications. It combines structured records, links between concepts, and searchable history so context can be retrieved when it matters.
Who we serve
We serve builders creating agentic products, teams operating AI workflows, and organizations that need continuity across tools and time. If persistent context is critical to your product quality, Maindex is built for you.
How it fits with your tools
Maindex is not a replacement for tools like Notion; they are complementary. Notion is where you organize work. Maindex is where your agents remember. Connect both via MCP and let your LLM bridge the two: pull project context from Notion into agent memory, or surface Maindex knowledge back into your workspace. Two tools, one agent, bidirectional flow.
Your data, portable by default
Export everything you have stored -- memories, links, collections, revision history -- at any time. Import it into a new account or keep a local backup. No walled garden, no gilded cage. Your thoughts, ideas, and knowledge belong to you.
