About

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.
