The full guide

What Rosie does

Rosie's site describes an answering service that you train from your website or Google Business Profile. It answers questions, books appointments, takes messages, filters spam and sales calls, transfers to a person when needed and texts you the details of every call. You set it up by forwarding your calls to it. Its examples include home services, law firms, salons and property managers.

When Rosie is the better choice

If you are a solo owner or a small team and the phone rings while you are with a customer, Rosie keeps those callers from going to voicemail. Booking straight into your calendar is on its Scale plan and above, and scheduling links by text are on every plan.

When OsmO is the better choice

The same owner still has to make calls: confirm a parts order, ask a landlord about a repair, check a licence renewal. With OsmO, you ask your AI app and it handles the call, including the phone menu and any hold queue, and reports back what was said.

  1. Open ChatGPT, Claude or another AI app and add OsmO from its connector or plugin settings.
  2. Sign in with your mobile number.
  3. Ask: "Call Hollis Auto Parts and ask if the brake pads for order 2210 have arrived."
  4. Read the answer when it comes back.

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

A simple test settles it. If your phone rings and you cannot answer, you need an answering service such as Rosie. If you keep a list of calls you have been meaning to make, you need something that makes calls, and that is OsmO For my AI. Plenty of small businesses have both problems, and the two tools work side by side without overlapping, because one listens on your line and the other dials out.

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.
