Multi-room music
Play music across rooms from the devices you already own. A phone, tablet, laptop, or old computer with a browser can become another room.
Switch your assistant.
Keep everything else. Viola plays music across rooms, makes outbound calls, handles email and calendar work, and runs browser tasks with your approval.
What Viola does
Email and calendar tasks
Ask Viola to check your inbox, draft a reply, find time on your calendar, move a meeting, or send the follow-up when you approve it.
Outbound phone calls
Viola places calls on your behalf, works through phone trees, keeps a record when enabled, and hands you the summary. US numbers only. See phone.
Browser tasks
Viola can open sites, compare options, fill forms, and stop for your approval at checkout or other high-risk steps.
Works with your stack
Use YouTube, Spotify, local music, Gmail, Google Calendar, and Home Assistant instead of rebuilding your life around a new ecosystem.
Local-first by default
Voice transcription, memory, API keys, payment cards, and browser profiles stay on your device by default. Cloud features are opt-in or account-backed.
