@Preuve AI

So I tested out Test Your Idea, and it actually works pretty well. You put in your idea, wait a minute, and it shows you the stuff you've been missing. Got some decent pivot suggestions that helped me refocus from a tiny niche to something way bigger. Saved me from probably wasting a few months in the wrong direction if you're actually gonna build something, not just daydreaming about it
