By stage · idea
AI tools for validating an idea.
The idea stage is about reducing risk before building. The tools below help validate demand, run lightweight surveys, sketch prototypes, and put concepts in front of real users — without committing to a tech stack or a team. Most are free or cheap; all let you test a thesis before you commit. Avoid heavy commitments at this stage; what you pick now you'll often abandon by MVP.
