# companyOS

> The context layer for AI. One signed record of how a company thinks, sells and decides, served to every AI it uses.

companyOS has no customer app. It compiles a company's record into a release, tests it, and serves it over MCP to Claude, ChatGPT, Microsoft 365 Copilot, Grok, Cursor and other clients. Views draw inside the conversation through MCP Apps.
