Answer what your agent needs from you, read the company's mail, contacts, files, and money, and change settings in the CofounderOS dashboard.

Answer what needs you, read the company's mail, contacts, files, and money, and change settings in the dashboard at app.cofounder.co/os.

Your agent runs the company through MCP or the CLI, and it can do or show you most of this in chat. A few things need you on the dashboard: adding payment methods, raising or removing a spending limit or the ad spend ceiling (the payer only), and entering sign-in credentials. Deleting a company isn't on MCP either; use the dashboard or cofounder org delete.

Finding Your Way Around

The rail on the left holds your apps. Home, Inbox, Messages, Contacts, Wallet, and Files are always there. Pin more from Add apps, and open Settings from the gear. Each live site your company runs also gets a tile that opens it in a new tab. On a phone, the rail becomes a tab strip.

Home, Apps, and Settings each have their own page.

Switching Companies

Open the account menu at the bottom of the rail to:

  • Switch between your Companies.
  • Start a New Company: name it, continue to checkout, then send the prompt it gives you to your agent.
  • Change the Theme (Light, Dark, or System).
  • Sign out.

The dashboard reopens the company you used last.
