OsmO is for the customer side: you ask ChatGPT, Claude or another AI app to call a business, including a dealership's service desk, and OsmO makes the call. If you run a dealership, look at Numa. If you need to ring one, OsmO can.

The full guide
Numa is dealership software
Numa's site says it is built for franchise dealerships and multi-rooftop groups with high call and text volume, mainly in service. It answers calls and texts, books service appointments, flags unhappy customers, keeps conversations in a shared inbox and connects to dealer management, scheduling and CRM systems. It names GM, Ford, Stellantis and BMW programmes, and says more than 1,500 dealerships use it.

When Numa is the right choice
If you manage a dealership and service-desk phones ring off the hook, Numa is specialist software for exactly that. It knows the systems dealerships use and the jobs their staff do, which a general tool will not.
When OsmO is the right choice
If you are a driver who needs to book a service, check whether a part has arrived or ask how long a repair will take, OsmO makes that call for you. It works the phone menu, waits on hold if the service line is busy, asks your question and puts the answer in your chat.
- Ask your AI app for the call, with the dealership and what you need.
- Your AI app or OsmO looks up the listed number, and OsmO dials.
- It picks the service option in the menu and waits if needed.
- You get the slots and prices they offered.
Need your own phone answered? The OsmO app can answer your calls too. This page covers OsmO For my AI, which places calls.
What it costs
OsmO For my AI starts with 50 free credits when you sign in with your mobile number, with no card. An answered call uses 3 credits however long it lasts, and a call nobody answers is free, so the free credits cover about 16 answered calls. When they run out you can keep calling from the OsmO app.
The bottom line
Numa and OsmO only overlap in one place: the moment a customer rings a dealership's service desk. Numa may be the voice that answers, and OsmO may be the one calling on the customer's behalf. If you are choosing software for a dealership, judge Numa against other dealership tools on how well it fits your dealer management system and service team. If you are a driver, you do not need dealership software at all, only something to make the call.
Where OsmO works
You can sign in with a mobile number from the United States, Canada, the United Kingdom or Australia (India too), and calls are placed from the OsmO number for your country. OsmO calls listed businesses in your own country, such as shops, clinics, restaurants and offices, and toll-free helplines. With the free web credits it does not call personal numbers; with the OsmO app it can also call your saved contacts.
