Most AI website review tools generate a generic report. Roast100 takes a different approach. Instead of one opinion, you get feedback from 100 AI critics with different personas, perspectives, and personalities—from ruthless VC investors and skeptical Fortune 500 CMOs to overworked developers and confused first-time users. Start with 3 free critics, then unlock all 100 for $5. Need actionable improvements? Add an AI Fix Plan that turns the harshest feedback into prioritized recommendations.
