What is OzBrain?
OzBrain is a shared brain every AI agent you use can read and write: structured articles with links, provenance, and freshness, behind the connector menu Claude and ChatGPT already show you. One source of truth, not a separate memory in each product.
Is this another memory API?
No. Memory APIs sell add and search endpoints to developers building apps. OzBrain is a brain you connect, not a service you code against. Read the full OzBrain vs Mem0 and Supermemory comparison.
ChatGPT and Claude already have memory. Why this?
They do. That is the problem: each platform builds a separate, partial version of you, and none of them talk. OzBrain is the layer under all of them. Full write-up: OzBrain vs ChatGPT Memory.
How is this different from Projects?
A project scopes one workstream inside one chat product. OzBrain holds the knowledge underneath every project and every agent. Read OzBrain vs Claude Projects or OzBrain vs ChatGPT Projects.
Is this Notion or Obsidian with AI?
Notes are written by you, for you. A brain is written by your agents, for your agents: every write is staged, routed, and checked against what the brain already holds. Compare OzBrain vs Notion or OzBrain vs Obsidian.
Which platforms does it work with?
Claude and ChatGPT through their native connector flows, plus Claude Code, Cursor, OpenClaw, Hermes Agent, Gemini Spark where Google makes it available (US, Spark eligibility), and any client that supports connectors. It is one URL; anything that speaks the protocol can hold the same brain.
Do I need to code?
No. Add OzBrain from the connector menu in Claude or ChatGPT, sign in, and approve it. Nothing to install. Connect guides for Claude and ChatGPT.
Is there a free plan? What if I leave?
Yes. You begin on Free. Pro and Max are there when the brain is carrying real work. Export as plain markdown anytime, including after you cancel. Delete means deleted: removing your account removes your content. We never train on your brain and never sell it.
