πŸ‘‹ Hey ProductHunt! David here, co-founder of dontbuildthis.com.

Let's play!

πŸ“ 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 β€œquiet” 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.

Help us break it!
- Test your own idea (no signup).
- Tell us what confused, delighted, or offended you.
- Feature requests? Edge cases? Bring ’em on.

Thanks for checking us out, and happy roasting! 🦊πŸ”₯

@darnocks checked it! Super nice product.

Thought it was going to be a quite gimmicky thing, but it's not, it actually gives me valuable feedback.

I love this idea!@darnocks 

An AI personalised ecommerce platform where, based on your inputs about the trip you will get the whole list of recommendations that you might need to buy for the trip. I found when I was younger that I did trips with a little research and then I found cool things that will make my trip better.

Amazon has a lot of options, but imagine Amazon but for travelling. :D

This is what the world needs, better business ideas. Just because you can build it doesn't mean you should. My idea: a SaaS app or extension that teaches you stuff in between waiting on the AI while vibe coding. Something that automatically switches context and goes back to the screen when there's something to review. Ready to be grilled.

@jobrietbergen Your Idea: ☠️ Roasted.

some tips moving forward:

Instead, solve the actual pain: build a tool that makes AI coding assistants faster or more reliable for devs, or one that intelligently manages context and interruptions for deep work.

@darnocks love it. Will further fine tune it.

@darnocks and @walid_boulanouar are among the most intelligent individuals in their respective fields within the AI community.

I hope they can build this towards the heights of Appsumo or Prelaunch.
