OpenBrain documentation

OpenBrain is shared memory for your AI apps — one place to save facts, preferences, and context so every assistant you use can recall them safely, scoped to your organization.

Choose the path that matches how you work:

Connect an AI app (recommended)

You use chat assistants, creative tools, or other apps that support MCP (Model Context Protocol). You do not need to write code.

1. Create your account and API key
2. Connect your AI app — overview and checklist
3. Follow a platform guide:
   • Claude (Desktop or web, when MCP is available)
   • ChatGPT
   • Gemini
   • Other MCP apps

After connecting, ask your assistant to use OpenBrain tools such as memory_search before answering questions that depend on prior context, and memory_ingest when you want something remembered.

Build with the API (developers)

You are shipping an agent, automation, or backend that calls OpenBrain directly.
