Is your app idea actually worth building?

A free quiz for outsiders and vibe coders. Score your app idea across 6 dimensions and find out if it's worth building — before you spend weeks on it.
ZeroHuman.
Nice launch! Which model scores the idea, and on what criteria across the 6 dimensions?
Build Check
@byalexai currently the score isn't AI — it's deterministic. Your answers to the 12 questions map directly to points across 6 dimensions (10 pts each, 60 total). AI only kicks in after your score to generate the competitor benchmark, ICP snapshot, next steps, and validation experiment. Given the feedback I'm getting here, I have several ideas to improve it

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?
Build Check
@uxpinjack I feel people is more surprised when score is good than the opposite. Seems like we tend to look for a reason to stop (or not) doing something
App Finder
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.

@konrad_sx thanks! Loved it. I'll work on that way
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
Build Check
@saad_el_gueddari aren't predicting shipping, just a quick filter for now. I'll keep working on the directions the feedback tells me
I tested it out with sample prompt: "Tool where I can create websites using prompting", it worked great with the suggestions in the first section, but I'd say it dropped the ball somewhat as Lovable isn't even listed as "tools that already solve something similar":

@yodalr thanks for sharing man! This kind of feedback is what I actually need to keep it up and useful for many founders. Gappy to get any other feedback from you Lennart
The "outsiders" framing is the interesting part — most vibe-coding tooling assumes you already know if the idea has shape. A 2-minute gut-check as a step zero is a nice wedge. Curious whether people actually kill ideas after a bad score, or whether the result just gets rationalised away.
Went in skeptical, came out with 3 concrete things to do this week on my idea. That's a win.

@silva_pabloj thanks man! tbh I went skeptical too but builders are finding it useful. I'll work on that way!
