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

Great app. I had never tried anything so specific and professional. The advanced mode is really comprehensive, even though it is quite complex for beginners. It’s truly Gym Bro–level. For now, I’m testing the training mode, which is more accessible for me.
