An AI operating system for running clients, projects, teams, communication, billing, and AI agents in one workspace.

How do AI agents work?

Agents connect from the outside through the API. You assign their credentials and permissions, and they operate inside the system within those limits.

Do you provide AI agents?

Not currently. You bring your own agents; internal agents may come later.

Can we use our own AI provider?

Yes. You are not tied to any provider.

Does it work without AI?

Yes. It works as a complete operations system on its own.

Does it support WhatsApp?

Yes. The WhatsApp Business API is integrated directly into the workspace.

Yes. Setup and customization are available as a separate service.
