What you can actually say to Viola

Viola is a voice assistant for Windows that does tasks, not just chat. Speak naturally: after you connect the relevant services, ask for the result you want. If you are switching from Siri, Alexa, or Google Assistant, everything below runs through the accounts and devices you already have. Why people switch.

Frequently asked questions

Can an AI assistant really make phone calls for me?

Yes. Viola places real outbound calls to US numbers: it works through phone trees, asks your question, and brings back the answer or a summary. It does not answer your inbound calls.

Do I need new speakers for multi-room music?

No. Any phone, tablet, or laptop with a browser becomes another room, playing in sync with the Windows hub. You use the devices you already own.

Do I lose my current setup if I switch from Siri, Alexa, or Google Assistant?

No. Everything on this page runs through the services you already use: your music providers, Google Calendar, your browser, and Home Assistant. The assistant is the only thing that changes.

What do I need to run Viola?

A Windows 10 or 11 PC (64-bit). Viola is free to start, and browser tasks that involve buying anything stop for your approval before checkout.
