WhittleOS

WhittleOS is a decision tool for one-person businesses that is built to say no. There are two paths. If you bring an idea, you answer four short questions, it runs 12 deal-breaker checks, scores seven areas and returns a verdict in under a minute along with a Whittle Score calculated for one person, the reasons, and the next thing to do. A hard failure on any single check ends it.

If you have no idea yet, you describe yourself and the service searches a market using real data, which takes 10 to 40 minutes and ends with an email listing up to five ideas (or nothing when the market offers little), each with evidence that people have the problem. Verdicts run from Build it through Test it first, a paid pilot and On hold, to Drop it, with the pass or fail line computed in code rather than judged by the model. The site publishes real runs and offers a source-linked pain library, a live feed of problems and a scored idea library. Signing up gives 2 free credits with no card, which are meant for checking ideas; the discovery search comes out of a paid credit pack.
