Most idea validators just wrap ChatGPT with a prompt. Ervin uses 6 AI agents that research and debate your idea using real market data. It finds real competitors with pricing, validates demand with Reddit and market reports, then runs advocate vs critic debate, VC and customer perspectives. You get a BUILD / PIVOT / KILL verdict plus a validation plan: 5 interview questions, a cold DM script ready to copy, and where to find your target users. Free: 2 sessions/month. No credit card.
