WhittleOS

Most tools tell you your idea is promising. WhittleOS is built to talk you out of the wrong one before you sink months into it. You give it a niche and your founder profile. It searches public sources itself — a search API, listing and review sites it's allowed to read, public job and discussion APIs — drops every candidate with no documented problem behind it, runs the rest through ten named deal-breaker checks, ranks what's left against your specific profile, and ends with one recommended first move plus the point where you should walk away. Not a chat; a funnel. The run we publish took 60 searches and 24 full pages read to turn 69 candidates into 5. A well-known AI validator scored one of our ideas 72/100 "promising." WhittleOS's Kill My Idea scored the same idea 15/100 — a KILL, with 10 specific reasons. One idea, two tools, opposite verdicts. We show our reasoning and make no accuracy claim. It's async by design: no interviews, no demo calls — validate with a landing page and a real CTA instead. New product, new domain. Kick the tires.
