## FAQ

### Does this use a headless browser?

No, it gives agents direct control of the browser you already have open, using your real sessions, logins, and cookies.

### Can multiple AI agents use the browser at the same time?

Yes, multiple agents can drive different tabs simultaneously through a single shared daemon without blocking each other.

### Is my data sent to the cloud?

No, everything stays on your local machine and communicates via localhost.
