▞ nichesim v.1

Hey Product Hunt, I’m the maker of ▞ nichesim.

Building is getting easier and easier. Learning is the bottleneck. Early on, you don’t need “the truth,” you need faster iterations and a clearer sense of what to test next.

▞ nichesim is simulates community through AI personas for you to validate and test your ideas. The goal isn’t to predict outcomes. It’s to surface likely questions, misunderstandings, objections, and angles that might work, so your next real-world test is tighter.

One thing that matters to me: this isn’t “AI decides.” The current version is built for human-in-the-loop use. With every generated simulation, you're able to comment to prompt and steer further conversations. You run a simulation, you judge what’s useful, you tweak the framing, and you run it again. It’s a fast thinking partner, not an authority.

It’s in beta right now. Near-term, I’m focused on making the personas more grounded and more shareable. The next version is also planned to support uploading real-world data so simulations and insights can be anchored to what you already have, not just what you type into a box.

If you try it, I’d love one piece of feedback: did it help you find a clearer angle to test, or a better way to explain what you’re doing?
