Hey PH 👋 I'm Cip, founder of Testly. Here's the honest version of why I built this. I kept noticing the same thing: smart people, heavy AI users, completely overconfident about their actual competency. Not because they were careless — but because getting outputs from AI feels like mastery. You don't see your own blind spots when the tool fills them in for you. The research backs this up. The more someone uses AI, the more confident they become — independent of whether their actual skills improve. It's a calibration problem, not a knowledge problem. The certification industry doesn't help. AWS, Google, PMP — they all charge $200–500 upfront. Fail? Pay again. The incentive is structurally backwards. So I built the opposite: L1 is free. L2–L4 cost money, but only if you pass. We earn when you succeed. That's the only model that makes sense to me. A few things people ask about: **Why blockchain?** Not for hype. Because certificates get faked, platforms shut down, and employers can't verify a PDF from a company that may not exist in 3 years. On Polygon, your certificate exists permanently and independently. We can't revoke it even if we wanted to. **Why scenarios and not multiple choice trivia?** Because knowing what "hallucination" means doesn't tell you anything about whether you'd catch one in a real work output. We test judgment in context. **Is L1 actually free?** Yes. No credit card, no time limit. testly.app/individual → click Start → done. Happy to go deep on: psychometric design, how we evaluate answers with Claude API, why Polygon specifically, or the EU AI Act angle for B2B. Ask anything — I'll be here all day.
