27 people — Chose B
Being able to put a wet umbrella away on a rainy day is really convenient in my busy life working in care. Having one less thing to dry after getting home means a lot when I am tired. Judging by practicality, this would make my life easiest.
I take one to school every day, so putting a wet umbrella straight away would be convenient. It would keep my bag clean.

How the 100 are made
Asking the same 100 shows the difference between options.
Data on 3,000 people in Japan
Built on synthetic data for 3,000 people in Japan, down to age, gender, region, work, and household finances.
A fixed 100 chosen from them
The 100 keep the age, gender, and regional mix of the 3,000, and the lineup stays fixed.
Compare options with the same 100
Changing the option does not change who you ask, so the difference shows up as a difference in numbers.
Asked 5 times in shuffled order
The options are shuffled and asked 5 times, and we tell you in words how often the most chosen option stayed the same.
The 100 customers are a fixed sample from our open dataset Japan Synthetic Personas (CC BY 4.0), built on NVIDIA Nemotron-Personas-Japan (CC BY 4.0) with household-income and consumer-behavior attributes added.

FAQ
Before you start,
common questions.
How is this different from asking ChatGPT?
In Urekata, a fixed 100 people with different ages and lives each choose one option and explain why. The options are shuffled and asked 5 times to see whether the answer holds. Because it is the same 100, you can also compare what changes when you change the option.
Is this a survey of real people?
No. They are 100 AI customers chosen from synthetic data on 3,000 people in Japan. Use them to narrow down which options to test before you ask real customers. For details, see Terms & data handling.
How accurate is it?
We do not show numbers that forecast sales or purchase rates. The options are shuffled and asked 5 times, and we tell you in words how often the most chosen option stayed the same. After you sell, paste the feedback you get to compare it with the sealed forecast and see how it holds up for your own product.
How is my product information handled?
Product information is sent to Anthropic's AI for the analysis and saved so you can see the result again. Only you can see your saved results, and you can delete them one by one from Your tests. For details, see Terms & data handling.
