Callio is an AI-powered application designed to make everyday calls to US businesses on your behalf. It handles tasks like making reservations, requesting appointments, and checking availability, providing you with a summary and transcript afterward.
You can find a US business through search or Google Maps, describe your request in your language, and confirm the call plan. Callio then places the call in English for you and sends you a summary and transcript once it's complete.
Callio is built for everyday calls to local businesses where a real person typically answers, such as restaurants, repair shops, and salons. It is not intended for chain hotlines or call centers.
No, Callio is ad-free. The application does not display advertisements, allowing for an uninterrupted user experience.
Callio offers 3 free calls to start. An unlimited plan is available for $4.99 for the first month, then $9.99 per month, with a 7-day free trial for the premium plan.
Your subscription automatically renews unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription anytime in your Apple ID settings.
