What it does
The only sustainable AI chat platform powered by green energy and hosted in Europe.
Powerful AI that respects your privacy and the planet. 100% renewable energy, European infrastructure, and up to 40% lower CO₂ than the major cloud providers.
A better world through efficient AI. Everything you need from AI: chat, search, documents, API. Hosted in Europe. Powered by renewable energy. Built without compromises. You tell AI things you wouldn't tell anyone else. Where does it go? Who reads it? And what does it cost the planet? For most AI platforms, the honest answer is: we'd rather not say. Your data crosses oceans, your prompts feed systems you can't see, and the environmental cost stays off the bill. GreenPT works differently. Your data stays in the EU. The models we run are open-source and audited. And every chat shows you exactly what it cost the planet. Our solutions combine AI Chat, a unified API, real-time CO₂ and energy…from greenpt.com

Claude 22023 · claude.ai · ▲248It was quite interesting to vibe code this artifact. I learned some basic ideas about commitment scheme and hash cryptography in the half and hour spent on this. One of the few times vibe coding left me feeling enriched rather than drained. What do you think?
