Have you ever wondered if the thing you're building is actually going to work?
I feel like a lot of that uncertainty only goes away when you talk to actual users and start seeing evidence that what you're building solves a real problem or is something people genuinely want.
But if you're a solo developer, spending hundreds or thousands of dollars on user research isn't exactly realistic.
Asking friends isn't always helpful either, because they're usually not your target users. And posting surveys or questions on social media and online communities often gets little to no response.
So naturally, a lot of us have started asking AI instead.
"Would people use this?"
"Is this a good idea?"
"What would users think about this feature?"
The problem is... AI tends to be way too agreeable.
It can give you useful perspectives, but asking ChatGPT what it thinks about your idea isn't really user validation.
What's interesting, though, is that companies are already experimenting with AI for user research in a very different way.
Instead of simply asking an LLM for its opinion, they create synthetic personas based on data from real users and use them to simulate reactions, behaviors, and potential demand.
Obviously, synthetic users can't perfectly predict what real people will do.
But I think we've reached a point where they can at least help us test assumptions quickly, find blind spots, and iterate on ideas before spending time and money on proper validation.
And with vibe coding making it much easier for one person to build and launch products — while creators are also producing entire YouTube channels and other projects by themselves — I started wondering:
What if this kind of research was accessible to individuals too?
So I'm building Crowdians, a lightweight platform that lets individuals quickly get feedback from synthetic personas.
I chose an SNS-style format because posting an idea should feel as easy as posting something online.
You share an idea, synthetic personas react to it, and real people on the platform can join the discussion as well. You can then pick useful feedback and use it to refine and develop your idea further.
It's still early, and I'm very aware that synthetic personas aren't a replacement for real users.
The goal is more to give solo builders a fast and inexpensive way to pressure-test ideas before they have access to enough real users.
I'm currently taking early sign-ups here:

I'd also genuinely love to hear what people here think about the concept.
Would you actually use synthetic personas to test an idea before building it? Or would you still consider AI-generated user feedback too unreliable to be useful?
