Most idea validators are feel-good machines: paste an idea, get a "promising" score, build for months on a vibe. WhittleOS is the opposite — deliberately kill-biased. It sources real candidates itself, links the problems it cites to the page each was read on or says when it's our own estimate, computes the score in code (not the model's own number), and returns nothing when a market's weak. Build / test-first / drop, with the reasons. No calls. Real, unedited run: whittleos.com/sample-discovery

Hey Product Hunt 👋 I'm Boris, solo founder of WhittleOS. I built it because most idea-validation tools are feel-good machines — paste an idea, get a 78/100 "promising", go build for three months on a vibe. WhittleOS does the opposite: it's deliberately kill-biased. It sources real candidates itself, links every problem it cites to the page it read it on, computes the score in code (not the model's own number), and honestly returns nothing when a market is weak. No calls, no coaching, no flattery. A real, unedited run, no signup: whittleos.com/sample-discovery — including a market that came back with nothing, because that's the point. It's early and I'd love the brutal feedback this crowd is good at. What would make you trust — or distrust — a tool like this?
