COMPARISON
Ex.Brain vs. the rest.
ChatGPT, Copilot, and Glean give individuals better tools. Ex.Brain gives the company a brain. The difference is the unit of memory: person vs. organization.
| Tool | Entry price/seat | Business tier | Enterprise floor | Min seats |
|---|---|---|---|---|
| ChatGPT Business | $20 annual / $25 monthly | — | ~$60/seat | 2 |
| Microsoft Copilot M365 | $30/seat | — | $30 (or $99 E7 bundle) | 1 |
| Claude Team | $30/seat | Custom Enterprise | Custom | 5 |
| Glean | (no self-serve) | — | ~$60–65/seat at $60K ACV | 100 |
| Ex.Brain | $30/seat annual | $200/seat | Custom | 3 |
Unit of memory
Copilot and ChatGPT remember per-person. Ex.Brain remembers per-organization. The company brain is a fundamentally different product category.
AI Members vs. copilots
A copilot answers your questions. An AI Member has a brain, a role, a budget, and a manager. It works — not just answers.
Security by architecture
Permission-Bounded Retrieval: the AI cannot surface what you couldn't already access. Not by policy. By architecture. No other product in this category makes that claim.
