Why Viola exists
Most assistants work best when you move deeper into the company that made them. Viola is built for the opposite move: change assistants without changing the rest of your life.
Keep YouTube/Google music paths, local files, Google Calendar where enabled, Home Assistant, and the services you already rely on. Viola connects to your stack instead of asking you to rebuild it.
What Viola does
Viola is a Windows hub with browser spokes for the rest of your devices. It plays launch-supported music across rooms, helps with calendar workflows where enabled, connects to smart-home systems through Home Assistant, and can handle longer tasks through a guarded browser agent.
Privacy is built into the product shape. Wake word and speech recognition run on your machine, desktop credentials stay on your device, and cloud features are opt-in. The Privacy Ledger shows what runs where.
How Viola is different
Viola is not tied to one ecosystem. The goal is simple: an assistant that works with the tools you already chose, keeps you in control, and stays quiet until you ask for help.
