Where StartupDeckAI is different

A free score, or a report you can check
ValidatorAI is the quickest way to get a reaction to an idea: a score, feedback and suggested next steps, at no cost. Its extra tools help with single tasks around validation, such as simulating customer objections or drafting landing page copy.
StartupDeckAI takes longer and goes further on evidence. It searches the web for competitors, sizes the market, outlines revenue, and labels each fact by where it came from, so you can see what was found and what was estimated.
Both have a free way in. Ours is 1 full validation a month on the Free plan, with Pro at ₹2,499/month for unlimited validations and every section of the report.
