likely to buy

Most indie makers build first and validate later — if they validate at all. WouldTheyBuy flips that order with a research-backed buying-intent signal grounded in the methodology from Semantic Similarity Rating (arXiv:2510.08338, Maier et al., 2024). In 60 seconds you get a clear startup idea test scored on a 5-point scale, with demographic-level breakdowns showing which segments actually want to pay. Use it to validate startup demand, compare positioning angles, or run a quick product demand check before you invest another week of build time. It is free, instant, and backed by peer-reviewed research.

Frequently asked questions
How is this different from asking friends if my idea is good?+
Friends tell you what you want to hear. WouldTheyBuy uses a peer-reviewed methodology (arXiv:2510.08338) to estimate actual purchase intent on a 5-point scale, with demographic breakdowns so you get signal, not politeness.
Can I use this to compare two ideas?+
Yes. Run each idea as a separate test and compare the purchase-intent scores side by side. It takes about 60 seconds per test.
Is WouldTheyBuy free?+
Yes, completely free. No signup, no credit card, no usage limits.
What if my idea gets a low score?+
A low score is still valuable — it means you can pivot early before spending weeks building. Use the demographic breakdowns and top concerns to refine your positioning or price.
