Short answer: most AI chat apps have no built-in way we could find to ring a business. Add a calling connector and they can: the AI works out who to call and what to ask, the connector places a real phone call, and the result comes back into the chat. These pages explain which apps can do it, how to set each one up, and what calls are worth handing over.
ChatGPT, Claude, Grok, Perplexity and coding agents can place real phone calls once you add the OsmO connector, on plans that allow connectors.
OsmO For my AI starts with 50 free credits, about 16 answered calls, and unanswered calls are free.
It calls shops, clinics, restaurants, helplines and toll-free numbers for people in the US, Canada, the UK and Australia.
50free credits when you sign in with your mobile number
3credits per answered call, however long
0credits when nobody answers
