What is the Open Memory Protocol?

The Open Memory Protocol (OMP) is an open standard that lets you backup, migrate, and own your AI conversations across every platform including ChatGPT, Claude, Gemini, Cursor, and more. Think of it as the iCloud of AI.

Can I export my ChatGPT conversations to Claude?

Yes. OMP provides connectors that convert ChatGPT exports into the universal OMP format, which can then be imported into any OMP-compatible platform. The process is: Export from ChatGPT → Convert to OMP → Import to Claude.

Yes. The OMP specification is published under CC BY 4.0 and all code (SDKs, connectors, reference server) is Apache 2.0 licensed. The standard itself is completely free. There is also a hosted cloud service (Memory Vault) with free and paid tiers.

How does OMP compare to MCP or A2A?

MCP (Model Context Protocol) connects AI to tools. A2A (Agent-to-Agent) governs communication between AI agents. OMP stores the resulting conversations from both. They are complementary standards — MCP and A2A handle the doing, OMP handles the remembering.

Can I self-host my own Memory Vault?

Absolutely. OMP provides a reference server as a Docker template that you can pull and run with a single command. It supports local-first, self-hosted, cloud, and hybrid deployment models.
