Multi-room music
Say it once, hear it everywhere. Your whole house plays in perfect sync. Any device with a browser becomes a speaker — iPhone, iPad, Android, an old laptop on the kitchen counter.
Private by default.
Cloud only when you say so. A voice assistant that lives in your house — plays music in every room, handles whole tasks with one sentence, and picks up the phone.
What Viola does
Whole-task agent
Triage email. Reschedule meetings. Compare three restaurants and book the best one. Research, draft, send. Viola figures out the steps and hands you the result.
Her own phone number
Viola answers your calls, places calls on your behalf, and hands you the summary. You pick up only when you want to. See phone.
One Viola, everyone in the house
Every person gets their own identity, calendar, memory, and accounts. The kids don't see your email. Your partner's Spotify doesn't become yours. Multi-tenant by design.
Works with what you already pay for
YouTube, Spotify, Apple Music, Tidal, Gmail, Google Calendar, Home Assistant for smart home. One Google login covers mail, calendar, and YouTube.
Privacy receipts, not promises

No ads. No agenda. No compromise.
Built by one developer in Wisconsin who got tired of assistants that work for corporations instead of people.
