AI Should Work
For You.
Most AI today asks you to choose: power or privacy. Innovation or independence. We don't think you should have to pick.
Melious exists to prove there's another way — AI that's powerful and private, intelligent and transparent, advanced and accountable. Built in Europe. Built on what actually matters.
The foundation
We didn't start with a product. We started with a question: what would AI look like if it were built for the people using it — not just sold to them?
Sovereign
Turns out, Europe already has everything it needs for independent AI — world-class inference providers, solid infrastructure, clear legal frameworks. It was just scattered. So we connected the dots: 100% European infrastructure across multiple regions, no US Cloud Act exposure, no American providers anywhere in the stack. Your AI, your jurisdiction.
Private
Privacy isn't a feature you toggle on. It's architecture. Your data stays yours because of how Melious is built — not because of what we promise in a policy. We can't read your prompts. We can't train on your conversations. We don't store what you ask, and we don't build profiles from how you use it. Everything is encrypted end-to-end, and our zero-knowledge setup means even we can't access what's yours. By default, your conversations stay local. If you want cloud sync, Melious Vault keeps everything fully encrypted — still untouchable, just available across your devices. What you ask Melious is between you and Melious. That's not a promise. That's how the system works.
Transparent
You should never have to wonder what's happening with your AI. Melious shows you everything: source citations on responses, which models answered, which countries and providers handled your request, the parameters used, clear pricing, full usage tracking — even the energy, CO₂, and water footprint of each query. No black boxes. No guessing.
Sustainable
Smarter architecture means smaller footprint. By using efficient, specialized models and renewable-powered infrastructure, Melious runs on at least 90% less CO₂ than traditional AI. The rest gets offset twice over — and you get to vote on which projects we fund.
This is just the beginning
We're building Melious in the open — not because it's trendy, but because that's how trust actually works. We'll share what we're learning, listen to what you need, and keep improving based on what matters to you.
