Smarter Together

Why a shared Brain beats everyone using their own AI in isolation.

Solo AI tools
Brain
Yet another tab to keep open — employees have to context-switch out of work to use it.
Employees already live in their inbox. Brain shows up where they already work — no new app to learn.
Knowledge resets every chat — nothing carries from one teammate to the next.
Every email teaches Brain. Company memory grows with each thread, the whole team gets smarter together.
Each employee picks one provider and is locked in.
Email any model from any provider. Mix Claude, GPT, Gemini, Grok per task.
Yet another login, outside your SSO and security perimeter.
Auth is your existing work email. No new accounts, no extra SSO setup.
Outside your DLP, retention, and eDiscovery — a compliance gap.
Inherits every email policy you already enforce. DLP, archiving, eDiscovery already cover Brain.
N vendors, N invoices, N seat audits to reconcile.
One consolidated Brain bill with per-team budgets and real-time dashboards.
