BetaStill building — not everything works yet
BetCheck
See who's behind this ↗

Describe what you're building. An AI pressure-tests your assumptions and generates a research brief, so you stop building on guesses you didn't know you were making.

The diagnostic and brief are free. The full research kit is $99.

One conversation. A plan you can defend.

Start messy. We’ll make sense of it.

Paste a landing page, drop in a PRD, or just describe what you’re building in a few sentences. BetCheck takes whatever you have and turns it into a structured conversation — no forms, no templates, no setup.

What builders say
Product Manager
“If the platform can handle the execution too — that’s a no-brainer. I’m putting this together with spit and glue like everything else. Having a brief that already has the test plan and the recruitment criteria? That saves me a week.”
— Product Manager
Fintech Founder
“You’re capturing what I wrote and digging into it. I was not expecting this. I thought it would just spit back a template but it’s actually responding to the specific thing I’m building. The research questions alone are worth it.”
— Fintech Founder
Designer & Strategist
“Okay wait, this is actually good. It gives me real pushback, not just a yes man. I described my product and it immediately asked me something I hadn’t thought about. That never happens with ChatGPT.”
— Designer & Strategist

The brief tells you what to learn. The Kit helps you learn it.

The Kit gives you everything to go from brief to fieldwork — no researcher required.
