WhittleOS
WhittleOS is a decision operating system built for solo founders and one-person businesses. It helps users determine which startup idea is worth building by combining structured checks, live market research, and evidence-based scoring. Instead of relying on generic advice from a chatbot, the platform runs real searches, reads source pages, and drops ideas that lack proof that a problem actually exists. The output is a clear verdict—Build it, Test it first, Try a paid pilot, Not yet, or Drop it—accompanied by reasons, an overall grade, and a recommended next move. At the core of WhittleOS are two entry points. When a user already has an idea, they answer four short questions, and the system applies 12 kill-checks and scores the idea on seven areas weighted for solo operation. A verdict is returned in about a minute. When a user does not have an idea, WhittleOS performs a discovery run across a chosen market or personal profile, searching live sources and public APIs to surface up to five opportunities that show evidence of real demand. In an unedited sample run, 69 ideas were considered, 36 were killed, and 5 were shortlisted. WhittleOS emphasizes honesty and falsifiability. It is designed to say no. The scoring is computed in code rather than left entirely to an AI model, and every check is transparent. Companion libraries such as a pain library, trending problems, and a scored idea library are publicly browsable, and each run lists the sources it actually read. The company contrasts its output with a generic chatbot, which can invent competitors and fluctuate in grading. Paid plans provide access to discovery searches and expanded credits, while new users receive a small number of free credits to test an idea without a payment card. WhittleOS is structured for first-time entrepreneurs, indie hackers, and solopreneurs who want to avoid spending months on weak concepts and need a systematic way to protect their time and effort.

Problem solved
WhittleOS solves the problem of false confidence in startup ideas by helping solo founders separate concepts with real evidence from those without a defensible problem. It replaces unstructured brainstorms and chatbot opinions with a repeatable, evidence-based process that recommends whether to build, test, or abandon an idea.
