Is your app idea actually worth building?
A free quiz for outsiders and vibe coders. Score your app idea across 6 dimensions and find out if it's worth building — before you spend weeks on it.
Results include AI-generated sections showing 3–5 real competitor tools, domain name suggestions, and an ideal first user profile. This gives context on what's already solving the problem and who to target first.
Build Check is designed for outsiders (managers, lawyers, salespeople, teachers) who see problems in their industry but lack technical background. It requires no coding knowledge and costs nothing, replacing expensive consultant fees with a structured framework.
Build Check generates a specific 48-hour experiment based on the idea's core assumptions—such as posting a landing page in a community or manually offering the service to test willingness to pay. This provides a binary signal on real demand before committing to development.
Build Check scores ideas across 6 critical dimensions (Real Problem, Frequency & Pain, Target Audience, Builder Fit, Demand Signals, Drive) in 2 minutes, providing an A–F grade and identifying the biggest risks. This saves weeks of wasted development on ideas that lack market fundamentals.
The quiz breaks down scores by dimension and generates AI-powered next steps tailored to the weakest areas (e.g., if audience specificity is low, it tells you to narrow your target first). This focuses effort on fixing the actual problem rather than abandoning the idea prematurely.
