§ I Evidence

Why a synthetic persona comes close to a real customer

A persona is only as good as what it's built on — three independent sources of evidence show how accurately AI mirrors human responses, how established the method already is in market research, and how solid its psychological foundation is.

Synthetic personas represent average perspectives and complement real user research — they don't replace it for final validation (NN/g 2025).

§ IV Questions

Common questions about the target-customer analysis.

How do I find my ideal target customers?

Enter your website address — the free target-customer analysis reads your positioning from your page content and derives your company profile and your most relevant target-customer segments. In about 30 seconds you see which target customers fit your offering best — and the synthetic personas that embody those segments. No sign-up, no credit card.

What is an ICP (Ideal Customer Profile)?

An ICP (Ideal Customer Profile) describes the type of customer for whom your offering creates the most value — in B2B, for example: industry, company size, role, and buying motive. Closely related is the buyer persona, which embodies the typical decision-maker concretely. Our target-audience analysis derives profiles like this automatically from your website and makes them tangible instead of leaving them abstract.

What is a synthetic persona?

Synthetic personas are AI-modeled profiles of your target audience, built with psychological depth. They respond to your content the way a specific type of user would — and deliver reviews with reasoned, quotable feedback in minutes. They complement real user research; they don't replace it.

How reliable are synthetic personas?

A Stanford HAI study (Park et al. 2024, n = 1,052) shows that AI agents replicate human responses with about 85% accuracy; according to Qualtrics (2025), 73% of market researchers already use synthetic responses, 87% of them satisfied. It's still important to keep this in context: synthetic personas represent average perspectives and complement real user research — they don't replace it for final validation (NN/g 2025).

Is the target-customer analysis really free and without sign-up?

Yes. The analysis is free, with no sign-up and no credit card — you only enter the public website address. We don't store any login credentials, there's no login and no newsletter requirement. Only once you'd like to use the personas afterward for testing do you create a free account.

How does the AI know who my target customers are?

The AI reads your website's public content — offering, value proposition, tone — and derives which target audiences you're addressing, the way an attentive visitor would. It then matches those audiences against our growing library of synthetic personas, built on Life-Worlds and the Big Five model.

What's the difference from ChatGPT or a survey?

A bare ChatGPT prompt delivers a generic opinion with no stable profile. Our synthetic personas are built with psychological depth (Big Five, Life-World, biography, decision style) and stay consistent across every test. Compared to a classic survey, you get first, reasoned reactions in about 30 seconds — a fast early step, not a replacement for real market research.

What can I do with the personas afterward?

The same personas then review everything you put in front of your target customers — website, ad, social post, product, email, or two variants in an A/B comparison — before it goes live. Every review comes with a reason, and you can follow up with the personas. You do all of this in your free account.

Where the method hits its limits

Synthetic personas represent average perspectives — not edge cases, and not real conversion data. For final validation, there is no way around real users. Synthetic personas complement real user research — they don't replace it.
