No Migration
Keep your stack
Viola is built for people who already have music services, Google Calendar, browser logins, and smart home tools. Switch the assistant, not everything around it.
Switch from Siri, Alexa, or Google Assistant. Keep everything else.
Viola is a voice assistant for your Windows PC. It replaces the assistant, not your music, calendar, smart home, or browser.
Why switch now (2026)
The big assistants are all changing under their users this year: Google is folding Google Assistant into Gemini, Apple keeps delaying Siri’s AI overhaul, and Alexa+ is paid for non-Prime users ($19.99/mo, free with Prime). If you are being pushed to move anyway, this is the moment to pick an assistant that answers to you. Compare Viola with Alexa, Google, and Siri, or see how Viola works.
What you keep, and what Viola adds
Work Done
Ask for the outcome
Viola can combine tools: check your calendar, prepare follow-up text, compare options in the browser, place an outbound call, and come back with the result. See real examples of what you can say.
Multi-Room
Multi-room audio without new speakers
Start music from the Windows hub and add rooms by opening a browser on a phone, tablet, laptop, or old computer. How multi-room audio sync works.
Phone
Outbound calls handled for you
Viola places calls on your behalf, works through phone trees, and gives you the summary. Phone is outbound only and limited to US/NANP numbers. See how phone works.
Browser
The web is part of the assistant
Viola can navigate websites, read pages, fill forms, and stop at approval gates for purchases and other high-risk actions.
Privacy
Local-first by default
Voice transcription, memory, API keys, payment cards, OAuth tokens, and browser profiles stay on your device by default. Cloud features are opt-in or tied to the account features that need them. The privacy policy and Privacy Ledger spell out what leaves your machine.
AI Choice
Use managed, BYOK, or local AI
Use Viola's managed AI, bring your own provider key, or configure a local model such as Ollama for supported local tasks. BYOK provider charges remain between you and that provider.
Hardware
No new smart speaker required
Viola runs from your computer and uses the microphones, speakers, phones, tablets, and laptops you already have.
Payments
Checkout stops for your approval
When Viola helps with a purchase, it pauses before checkout for your review. Saved cards stay in the local encrypted vault and are not sent to Viola servers.
Plans
Start free, upgrade when you need more
Local-first features and BYOK/local AI are available without a paid plan. Paid plans add a higher managed AI and phone usage allowance. See Free, Pro, and Max plans.

Frequently asked questions
Will I lose my music, calendar, or smart home if I switch to Viola?
No. The Viola Windows desktop app connects to the services you already use: Spotify, YouTube and Google music paths, local files, Google Calendar, and Home Assistant. You switch the assistant, not everything around it.
Do I have to switch to Gemini when Google Assistant goes away?
On Android, Google is moving people from Google Assistant to Gemini. On your Windows PC you have a real choice: Viola is a voice assistant you install yourself, and it is not tied to Google, Apple, or Amazon.
Is there an Alexa alternative without a subscription?
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. Paid plans only add larger usage allowances; features are the same on every plan.
Does Viola work on Mac or iPhone?
Viola is a Windows desktop app today (Windows 10 or 11, 64-bit). If you are on another device, leave your email on the download page and we will send one email the day Viola reaches your platform.
Is Viola more private than Alexa, Siri, or Google Assistant?
Viola is local-first by default: voice transcription, memory, API keys, payment cards, OAuth tokens, and browser profiles stay on your device. The Privacy Ledger documents what leaves your machine, capability by capability, so you can check the claim instead of taking our word for it.
Can I bring my own API key (BYOK)?
Yes. Use Viola’s managed AI, bring your own provider key, or configure a local model such as Ollama for supported local tasks. BYOK provider charges remain between you and that provider.
