Provek measures how much of a business runs without a human in the loop. It looks at each business operation on its own and assigns it a level from evidence, not from what the company claims. Every result is a public passport. It shows the evidence behind each number and says plainly what Provek...

As answered by people managing Arize and Provek.dev.
Provek.dev's answer:
Anyone can write "AI-powered" on a landing page, and nobody can tell that apart from a business that machines actually run. I wanted a way to check the claim per operation, with the evidence in the open and the method public. Provek is the result. It works as an ERC-8004 validator: the standard gives identity and transport, and the methodology is ours.
Provek.dev's answer:
Python for the measurement and registry, TypeScript with Preact and Vite for the site, Tailwind CSS, Cloudflare Pages for hosting, and ERC-8004 for identity.
Provek.dev's answer:
Provek scores each business operation on its own, from L0 to L5, and never gives one number for the whole company. Evidence is ranked by how hard it would be to fake. When Provek cannot measure something, the passport says why instead of writing a zero. The method is public, so anyone can recompute a verdict from the same inputs.
Provek.dev's answer:
Most claims about AI-run businesses are a line on a landing page. Provek checks them from the outside, anonymously, and shows the evidence next to every number. It also shows its own gaps. If you want a claim you can check, that matters more than a badge.
Provek.dev's answer:
Founders who run parts of their business with AI agents and want a public, checkable record of it. Also buyers, partners and investors who need to tell a real automated operation from marketing copy.
