Frequently asked questions
What is Viro AI?
Viro is a free AI assistant that brings ChatGPT, Claude, Gemini, and our own Viro AI model together in one app — on web, iOS, and Android. The difference: Viro runs on clean energy and puts its profits into climate projects, so time spent with AI helps the planet instead of costing it.
What is sustainable AI?
Every AI message is processed in a data center, and data centers use a lot of electricity. Sustainable AI means running that computation on clean power. Viro's own model runs in data centers powered by renewable energy, and for partner models we match the energy behind every message by funding verified wind, solar, and battery projects.
Is Viro AI really 100% clean energy?
Our own model, Viro AI, runs entirely in data centers powered by renewable energy — hydro, geothermal, and wind — clean by geography, not by certificates. When you use partner models like ChatGPT, Claude, or Gemini, we estimate the energy behind each message and fund matching clean power, and we label the difference so you always know which is which.
Does Viro use carbon offsets?
Our own infrastructure doesn't need them — Viro AI's data centers run directly on renewable power. No offsets, no funky accounting. For partner models hosted elsewhere, we fund clean energy to match their estimated usage, and we label that clearly as energy matched rather than calling it 100% clean. On top of all of it, profits fund verified climate projects.
Does Viro AI use water?
Far less than typical AI. Data centers usually consume water through evaporative cooling; Viro's sites sit in cold northern climates where outside air and closed-loop liquid cooling carry the load instead. Our Norwegian site draws fjord water at 6–9°C in a closed loop and returns it warm — on to nearby fish farms, not evaporated away.
How is my climate impact calculated?
We estimate the electricity each message uses based on the model and the length of the response, then fund enough new clean energy to match or exceed it. You can watch it add up in the app: kWh of clean energy added, CO₂e avoided, and homes powered.
How is Viro different from ChatGPT?
You don't have to choose — Viro includes ChatGPT, plus Claude, Gemini, and Viro AI, and you can switch models anytime. Unlike ChatGPT, Viro gives you all four in one app, goes ad-free for $4.99 a month instead of $20, runs its own model on clean energy, and funds climate projects with its profits.
Is Viro really free?
Yes. Unlimited AI chat, free on web, iOS, and Android. Free chats may show a small sponsored card — those ads fund the clean energy behind your messages.
What do the paid plans add?
Ad-free ($4.99/month) removes ads. Supercharged ($12.99/month) removes ads and multiplies your climate impact 10x — we fund ten times the clean energy your usage requires.
Where does the money go?
All profits — from ads and subscriptions alike — fund verified clean energy and climate restoration projects: wind farms, solar, and battery storage.
What about privacy?
We never sell your data or build an advertising profile of you. Ads are matched automatically to keywords in the current conversation — never to your identity — and no human reads your chats. You can delete any conversation at any time.
Which AI models can I use?
ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), and Viro AI. Switch per chat or mid-conversation — each model has different strengths.
How much energy does AI actually use?
More than most people think — data centers already draw a meaningful share of global electricity, and AI is the fastest-growing part. That's why we run on clean power and publish our data centers and energy stats openly.
Who is Viro for?
Students, researchers, creatives, climate nerds—anyone who chats with AI and wants their time online to mean something.
