What happens next

1

Run ViolaWebSetup.exe, a quarter-megabyte downloader (the same pattern Chrome and Zoom installers use). It fetches the full app (about 777 MB - Viola ships her voice models) with a progress bar, verifies the file’s fingerprint, then installs. Two to six minutes on typical home internet.

2

If Windows shows a SmartScreen prompt, choose More info, then Run anyway. New releases earn Windows’ trust download by download; every build is code-signed through Microsoft’s Trusted Signing service, and the signature details below let you verify yours before running it.

3

Say “Viola” and hand her something real: play music in the kitchen, call the dentist, plan your week.

Frequently asked questions

Is Viola free?

Yes. Viola is free to use with a monthly managed usage allowance, and it stays free if you bring your own API key or run a local model. Pro ($12/month) and Max ($20/month) add larger allowances; features are the same on every plan. See plans.

Does Viola work on Mac, iPhone, or Android?

Not yet. Viola runs on Windows 10 or 11 (64-bit) today. Pick your device above and leave your email; we will send one email the day Viola reaches your platform.

Is it safe to run ViolaWebSetup.exe past the SmartScreen warning?

Yes. Every build is code-signed through Microsoft’s Trusted Signing service, and the page shows the installer’s SHA-256 fingerprint so you can verify the exact file before running it. New releases earn SmartScreen’s trust download by download, which is why the prompt can appear on a fresh release. Our security practices cover the rest.

What can Viola actually do once installed?

Play music in sync across rooms using devices you already own, place real outbound phone calls to US numbers, keep your Google Calendar in view and plan your day, run browser tasks that pause for your approval, and control a Home Assistant smart home by voice. How it works.

Do I need an account or credit card to install?

No. Viola installs and runs without a card and without creating an account. Some features that run through Viola’s cloud, like phone calls, ask you to sign in before first use.

Verify the installer signature & hash

Code-signed through Microsoft’s Trusted Signing service (certificate chain: Microsoft ID Verified CS PCA 2021). Confirm the signature and publisher in PowerShell:

Get-AuthenticodeSignature .\ViolaSetup.exe
Get-FileHash .\ViolaSetup.exe -Algorithm SHA256
