fonio.ai
In short

In 30 seconds.

fonio.ai fits if …

you have a lot of call minutes, serve callers in several languages, your calendar already lives in Calendly, HubSpot or a CRM, and you want a phone-only tool.

terminio.ai fits if …

your calls are appointment requests and the assistant should book into the same calendar as your booking page, with a WhatsApp confirmation afterwards, without a second tool.

The biggest difference

Minutes versus calendar. fonio Solo has five times the minutes and is cheaper on annual billing; terminio has the calendar, the booking page and WhatsApp in the same plan.

Features

Point by point.

Eleven rows that count for a phone assistant: does it book, is the number included, how many minutes, what does it need around it. Whatever fonio.ai does not say publicly stays a question mark and never counts as a no.

Typical in these industries.

Switching

From fonio.ai to terminio
in three steps.

  1. 01

    Set up services and hours

    Tap your industry, check the services with duration and price, set opening hours. The assistant books only what is really free in the calendar and says only what you entered.

  2. 02

    Number and forwarding

    terminio gives you a German phone number. You forward: always, only when nobody picks up, or outside opening hours. Your existing number stays; the fonio number you cancel.

  3. 03

    Greeting, voice, test call

    Write the greeting, choose a voice, call yourself. Until the fonio term ends both run in parallel; one number can only go to one assistant, and you decide which.
