As someone who's built a few too many things that are not worth my while, this seems like a good idea.

Cool! Where do you want to deliver your quizes? (I mean any aspiration to pub quizes, schools etc?) :)

Nice I'll for sure try this when I've got more time on my hands!
If something is a totally novel idea with no "prior art" how is the answer derived in that case?

What is you future plan about sustaining it? I my view, this should not have any cost for participants. And you'd need a strong iedntity verification system. Plus, this can become a marketing platform as well. A lots to think about. I'm sure you did your study. Great idea. Congrats.

Love the focus on outsiders specifically. That perspective is usually what teams are missing. What’s been the most surprising insight people have gotten from using it so far?

Can sure be helpful for a lot of people! The questions look sensible to me. I'd add doing a comprehensive web search to check if a tool that can solve the problem does exist already.

Nice launch! Which model scores the idea, and on what criteria across the 6 dimensions?
[Redacted] • Apr 17, 2026
this is great tool to save 2 years building something nobody wants.

Looks like very useful for indiehackers/builders :) @german_merlo1

How often does your application say that an idea is not worth building.
[Redacted] • Apr 17, 2026
Went in skeptical, came out with 3 concrete things to do this week on my idea. That's a win.

the outsiders angle is real like half the best products come from someone who got tired of a problem at their day job. but the "should i build this" question is usually cope, people who ship don't need a filter they need a deadline. curious if a high score actually predicts shipping, or just makes people feel smarter about sitting on the idea

Congratulations. And happy product launch. @german_merlo1
[Redacted] • Apr 17, 2026
Interesting and useful idea! Congrats!
[Redacted] • Apr 17, 2026
Cool idea! Validation part is super important, but not many founders pay enough attention to that
[Redacted] • Apr 17, 2026
Great idea but how do you score each dimension? Did you build own algorithm or rely on AI? From business point though, are you planning to monetise this app (because for me it's hard to understand how you can build recurring revenue here)? Congrats for launch and good luck!

👋 Hey Product Hunt!I’m German. I build a lot, I learn a lot, and I’ve noticed a massive shift.The "Outsiders" are coming. Managers, lawyers, and even employees who see real problems but don’t know if their solution makes sense as a product. I’ve answered the "Should I build this?" question 100+ times this year.So, I vibecoded a 'solution'.Build Check is a
