"EU-hosted voice AI with real calendar booking and outstanding support"

5/5

What do you like best about fonio?

We use fonio to build AI phone assistants for small businesses. Three things convinced us: First, hosting in the EU, which is a must for our clients. Second, appointment booking directly within the call – the assistant checks the calendar live, books the slot and then sends a structured summary by email. Third, transparency: the action details show for every call which tools were used with which parameters, which makes troubleshooting and fine-tuning the prompt much easier. On top of that, the support team answers even detailed technical questions point by point and honestly. Compared to other voice AI platforms we work with, the collaboration with the fonio team is noticeably more direct and solution-oriented. Review collected by and hosted on G2.com.

What do you dislike about fonio?

The platform evolves quickly, and not every change is documented right away – after updates it is worth double-checking your own configuration. Some behavioural details can only be controlled via the prompt rather than through a setting, which requires some experience in prompt design. Review collected by and hosted on G2.com.

What problems is fonio solving and how is that benefiting you?

Small businesses miss calls while everyone is busy in the workshop – and with them, jobs. With fonio, an assistant takes the request, books an appointment and the team receives everything in one place. For us as an implementation partner, fonio is the foundation on which we set up such assistants for our clients. Review collected by and hosted on G2.com.
