I have no CRM and no digital calendar — does it still work?

Yes, and it's a common case: by default everything lands in email and texts on your mobile. The summary of each missed call arrives in your inbox with the transcript and number, you reply to the caller directly, and the central point remains the dashboard, viewable in a browser with nothing to install. For appointments, if you work from a paper diary, the AI offers slots based on your declared opening hours and you approve with one click; without approval, nothing is confirmed to the customer. The service is designed for a solo operator with a phone in their pocket, not for an IT department.
