Build Check

Build Check is a web‑based quiz that lets anyone evaluate an app concept before investing development time. Users answer twelve questions that map to six predefined dimensions—Real Problem, Frequency & Pain, Target Audience, Builder Fit, Demand Signals, and My Drive—each scored out of ten. After completing the two‑minute assessment the tool presents a total score out of sixty, a letter grade, a brief verdict, and concrete next steps tailored to the weakest dimensions, including a short‑term validation experiment.

The service targets non‑technical domain experts such as managers, lawyers, teachers, and salespeople who have identified a potential problem in their field and want a structured way to gauge its viability. It is also useful for “vibe coders” who tend to start building without confirming demand. The quiz can be taken directly on the site or embedded elsewhere, and a prompt is provided for AI assistants like Claude, ChatGPT, or Gemini to run the same six‑dimension framework.

Build Check is free, requires no registration, and delivers an instant scorecard with AI‑generated recommendations, helping users decide whether to pursue an idea or refine it before writing any code.
