WouldTheyBuy is built on the methodology described in Semantic Similarity Rating: New Approach for Product Idea Evaluation (arXiv:2510.08338, Maier et al., 2024). Instead of expensive surveys or guesswork, you get a research-backed purchase-intent estimate in about 60 seconds. The system scores likely buying interest on a 5-point Likert scale and breaks results down by demographic segments — age, income, and lifestyle — so you can see exactly who your strongest potential customers are. Use it to test your product idea, validate demand before launch, or compare positioning angles side by side. It is free, requires no signup, and every result is shareable. Whether you are validating an idea for the first time or refining a concept you have been working on, this gives you a fast, directional signal grounded in published research before you spend money on ads, development, or customer interviews.

Frequently asked questions
How does WouldTheyBuy work?+
You describe your product idea and set a price. Our system uses a research-backed methodology (published in arXiv:2510.08338) to estimate how likely people are to buy, scored on a 5-point Likert scale with demographic breakdowns.
Is WouldTheyBuy free?+
Yes, completely free. No signup, no credit card, no hidden limits. You can run as many tests as you want.
How accurate is the purchase-intent estimate?+
The methodology is grounded in peer-reviewed research on semantic similarity and purchase intent. It gives you a directional signal — not a guarantee — so you can make faster, more informed decisions about what to build or sell.
What data do I need to get started?+
Just a one-sentence description of your product idea and a target price. No spreadsheets, no customer lists, no prior research required.
How is this different from a survey?+
Surveys take weeks to design, distribute, and analyze. WouldTheyBuy gives you a research-backed signal in about 60 seconds using published methodology, so you can iterate on your idea before investing in formal research.
Can I share my results?+
Yes. Every result gets a unique shareable link you can send to co-founders, investors, or teammates.
