Demographic Personas and User Testing with AI Reasoning Models

As AI continues to evolve with advanced reasoning and contextual understanding, tools like ChatGPT have emerged as powerful allies for marketers and business owners seeking deeper insights into their customers. At the heart of every successful business is a clear understanding of its customers—their values, behaviors, preferences, and purchasing motivations. Traditionally, acquiring such detailed persona information involves significant time, resources, and financial investment through demographic assessments, usability testing, and customer surveys.

However, there is now a remarkably effective alternative available at your fingertips. AI-driven platforms like ChatGPT, Grok, Gemini and others allow businesses to efficiently perform fundamental testing and gain rapid insights into customer demographics and behaviors. All for free.

Below is a practical demonstration—actual dialogue excerpts with ChatGPT 4.5—that showcases how easily and effectively marketers can craft prompts to reveal valuable customer insights. These dialogues illustrate clearly the potential of AI to steer your business toward greater customer alignment, satisfaction, and ultimately, success.

Step 1: Initial Prompt to Generate Demographic Personas

Let’s launch a new chat in ChatGPT4.5 or Grok 3 to leverage the reasoning power and contextual understanding of advanced large-language models. Here is an example prompt (used with the permission of the business) that will get us started.

Prompt:

“Hogentogler is a company that sells scientific equipment in the categories listed below online at hogentogler.com. **First** Browse to the website to learn more about the company

**Second** Give me ten demographic personas (regular people) who would be buyers of equipment from this website, and give a bit of relevant background for each. We will use this list of demographic personas to generate customer-insights in future prompts, so choose the details about them that are most likely to be helpful in running usability and insights questions against.

Take it Further

The above prompts are just a scratch at the surface of what’s possible. One can easily level up by adding more context to the initial prompt where we gather customer personas. We can ask for 20 or 50 customer examples and ask for a broader spectrum of priorities and preferences.

We can ask for detailed questions about website usability, advertising preferences, promotional preferences and more.

We can make more informed buying decisions when expanding our product offerings.

As business owners and marketers, we can take some of the pressure off of our gut and let AI steer us with better context and objective viewpoints.
