Don't build the wrong stuff. Paste any idea into dontbuildthis.com & let Roasty the Fox smash it against live trend data, competitor signals & our private vault of wins & flops. You get a brutal score, verdict > pivot tips so you can validate in mins, not months. No signup, free to use.
👋 Hey ProductHunt! David here, co-founder of dontbuildthis.com.
Let's play!
📝 Drop a 1-line pitch in this thread... Roasty (a.k.a. me for today) will reply with a mini-verdict to the first 50 ideas. Let’s see whose concept survives the flames!
Launch perk for the PH crew
Every Product Hunter gets 30 days of our advanced tier = just use the in-app code PH-ROAST.
Why we built it??
After years of building and hanging out in builder communities, hackathons and innovation labs (and too many “quiet” product funerals) we realised most ideas die before code ever matters = they die because nobody truly needs them. So we turned our internal validation process into an AI-powered (duh), brutally honest and constructive fox called Roasty. Paste a pitch, Roasty slams it against real market data + our vault of wins & flops, then spits out a brutal score and pivot tips. It has already roasted 10k+ ideas inside our venture studio, saving teams months of wasted work.
