Viola vs Gemini
Gemini is becoming the built-in assistant on Android. If you would rather not have your assistant chosen for you, Viola is a Windows assistant built to do tasks, not just chat, and it is not tied to a Google account.
Two different kinds of assistant
Gemini is a strong general AI. It writes, explains, answers questions, and is now stepping in as the assistant on Android phones. Viola is a different kind of tool. Its focus is getting real tasks done on and around your computer: placing an actual phone call to a US business and working the whole call, doing browser research and form-filling with an approval step before checkout, controlling smart-home devices through Home Assistant, and playing synced music across rooms.
The two overlap on the "ask a question, get an answer" part. They separate on everything that touches the world outside a chat window. This page is for people who are being moved to Gemini and want to know what a task-focused assistant looks like instead, or alongside.
Chat vs doing the task
| Job | Gemini | Viola |
|---|---|---|
| Answers and writing | A core strength: conversation, drafting, explaining. | Handles questions, but this is not its main focus. |
| Outbound phone calls | Not a phone-calling agent for businesses. | Places real US carrier calls, works the phone tree, waits on hold, and summarizes. How phone works. |
| Browser tasks | Can browse and summarize in its own surfaces. | Navigates sites, fills forms, and pauses for your checkout review. |
| Smart home and music | Tied to Google Home and Google's music surfaces. | Uses Home Assistant when you run one; plays YouTube and Google music paths and local files across rooms. |

Who chose the assistant, and who chose the model
The part that pushes people to look for an alternative is not Gemini's quality, it is that the switch is being made for them. On Android, Assistant is being replaced by Gemini whether or not the user asked. On a Windows PC, you get to make the call yourself. Viola is the assistant layer, and it lets you pick the AI behind it: managed AI, your own provider key, or a local model. If you want a Google model through your own key, that is allowed too. The point is that you choose, rather than being moved.
| Decision | Gemini | Viola |
|---|---|---|
| Who picks the assistant | Becoming the default on Android. | You install it on Windows by choice. |
| AI model | Google's Gemini models. | Managed AI, your own API key, or a local model such as Ollama for supported local tasks. |
| Account tie | Runs inside your Google account. | Not tied to Google, Apple, or Amazon. |
Privacy and cost
| Control | Gemini | Viola |
|---|---|---|
| Default data posture | Runs in Google's cloud inside your account. | Voice transcription, memory, API keys, OAuth tokens, payment cards, and browser profiles stay local by default. Privacy Ledger. |
| Price | Free tier, with a paid plan for more. | Free tier with a monthly managed usage allowance; stays free with BYOK or a local model. See plans. |
Frequently asked questions
What is the difference between Viola and Gemini?
Gemini is a general AI assistant from Google, strong at conversation, writing, and answering questions, and it is becoming the built-in assistant on Android. Viola is a Windows desktop assistant focused on doing tasks: placing real phone calls, running browser work, controlling smart home through Home Assistant, and playing music across rooms. They overlap on questions and answers but aim at different jobs.
I do not want Gemini as my assistant. What can I use instead?
On Android, Google is moving people from Assistant to Gemini, but on a Windows PC you can pick your own. Viola installs on Windows, is not tied to a Google account, and lets you use managed AI, your own API key, or a local model instead.
Can Viola use Gemini as its AI model?
Viola lets you choose the AI behind it. You can use Viola's managed AI, bring your own provider key, or configure a local model. If you prefer a Google model through your own key, that is your choice; Viola is the assistant layer, not a single locked-in model.
Is Viola private compared to Gemini?
Viola is local-first by default: voice transcription, memory, API keys, OAuth tokens, payment cards, and browser profiles stay on your device. Gemini runs inside your Google account in Google's cloud. The Privacy Ledger documents what leaves your machine so you can check the difference for yourself.
Does Viola run on the phone like Gemini?
Viola is a Windows desktop app today. You can add rooms by opening a browser on a phone or tablet, but the assistant itself installs on Windows, not as a phone assistant. If you want it on other platforms, leave your email on the download page.
The switch point
Gemini is a capable assistant, and you can keep using it. The reason to look at Viola is not that Gemini is bad, it is that a Windows PC lets you choose your assistant and the model behind it, and that Viola is built to actually do the task rather than describe it.
