Free AI critique and scoring for startup ideas
ValidatorAI takes a written business idea and returns a structured critique: a viability score, the likely customer, competitive pressure and a suggested sequence of validation steps. Around that sits roughly two dozen single-purpose generators covering market sizing, value proposition, naming, pivots and a simulated customer-feedback panel, plus a public dashboard of aggregated founder submissions. It is browser-only, sign-in is through Google, and nothing on the site carries a price.
No paid tier or credit pack is advertised anywhere on the site; a Google sign-in saves results and there is a newsletter rather than a subscription.
Use tool ↗Useful as a free, slightly harsh first reader for an idea you have not shown anyone yet — it will name the obvious objections in a couple of minutes. Treat the output as a prompt to go talk to customers, never as evidence that a market exists.
Watch out: You are pasting an unlaunched business idea into a free site with no published corporate entity or retention policy — leave out anything you would not post publicly.
Side-by-side fact sheets against the competitors our research names — pricing, platforms, API and both verdicts on one page.
