Preuve AI is a startup idea validation platform that uses multiple specialized agents to examine market demand, competitors, pricing, funding, community discussions, and other live evidence. Its initial Reality Check returns a viability score and a direct build, revise, or stop signal.
The deeper Founder Report expands the analysis into market sizing, founder fit, positioning, customer acquisition, risks, and pivot options. Claims are linked to sources so founders can inspect the evidence rather than relying on an unsupported AI opinion.

How to use this tool
Describe one specific customer, painful problem, proposed solution, region, and business model before running the free Reality Check.
Open the linked sources and verify that competitors, demand signals, dates, and market boundaries match the intended idea.
Use a Founder Report when its deeper sizing, positioning, founder-fit, or go-to-market analysis could change the build decision.
Correct wrong assumptions with the refine controls and compare a revised idea rather than treating the first score as final.
Validate the strongest claims with customer interviews, experiments, and professional financial or legal advice before investing.
