Customer research

Simulate customer reactions to sharpen your real research

Test messaging, value props, and ideas against simulated audiences in minutes — a fast complement to, not a replacement for, real interviews and surveys.

MiroFish — customer research simulation with AI personas

MiroFish simulates how an audience might react to a message, value proposition, or idea — a fast, cheap first pass that complements real customer research rather than replacing it. You describe the audience and what you want to test, and the engine models that audience as AI personas that react and discuss over several rounds. It returns an estimated-probability read on which angle resonates, the main objections, and how sentiment splits. Be clear on the honest limit: these are AI personas reasoning about your scenario, not real humans, so the output is directional. Use it to decide which questions are worth spending real interview and survey budget on.

How MiroFish simulates it

A research simulation is a rehearsal, not a survey — here is the loop:

  1. 1

    Describe the audience and the question

    Who you are testing with (segment, role, context) and what you want to learn — a message, a value prop, a feature, a content angle. The more specific the audience, the sharper the simulated reaction.

  2. 2

    Generate the personas

    The audience becomes AI agents with distinct motivations and objections, so the simulated reactions conflict the way a real panel’s would rather than converging on one view.

  3. 3

    Simulate the discussion

    Agents react to your test and to each other over multiple rounds. Enthusiasm, indifference, and objections emerge, along with which framing pulls the group.

  4. 4

    Read the directional report

    An estimated read on which angle resonates, the dominant objections, how sentiment splits, and what to test next — explicitly framed as a hypothesis to validate with real customers, not a finding.

A worked example

A B2B fintech blog targeting CFOs wants to know which of three content pillars will engage most: regulatory explainers, peer-benchmarking data, or automation how-tos.

Illustrative output — and a hypothesis, not a finding. Validate the winning angle with a small real test before committing a quarter to it.

What it can’t do (honest limits)

  • These are AI personas, not real customers — it does not replace interviews, surveys, or usability tests.
  • It cannot report real demographics, willingness-to-pay, or statistically valid sample data.
  • It is strongest at generating and ranking hypotheses to test, weakest as a source of truth about real behavior.
  • Simulated agents can converge too readily; treat a strong consensus as a prompt to check it with real people.

Questions people ask

Can I do customer research without surveys or a panel?

You can run a simulated first pass in minutes: MiroFish models your audience as AI personas that react to a message or idea, returning a directional read on what resonates and the main objections. It is a complement to real research, not a replacement — it helps you decide which questions and angles are worth the cost of a real survey or panel, which you should still run before committing.

How do I test messaging before launching a campaign?

Describe the audience and the messages you are weighing, and the simulation estimates which framing pulls the group and which objections surface — comparing variants side by side. Comparative runs are sturdier than a single test. The output is a hypothesis about the strongest message, meant to be validated with a small real audience before you spend the campaign budget.

Can AI simulate how customers react to an idea?

Yes, with an honest caveat: it simulates AI personas reasoning about your idea, not real buyers. That still surfaces enthusiasm, objections, and how opinion splits — useful, directional signal you can get in minutes. Treat the result as a well-informed hypothesis to test with real customers, not as evidence of real behavior.

How do I predict which value proposition resonates?

Run each value proposition as a variant and compare how the simulated audience reacts — which one earns enthusiasm, which triggers “so what,” and the objections each raises. The report ranks them with an estimated read. Because these are personas, use the ranking to choose what to test for real, not as a final verdict on which prop wins.

Is simulated customer research reliable — and where does it fail?

It is reliable for what it is: fast, cheap hypothesis generation and ranking, and for surfacing objections you had not considered. It fails as a source of real numbers — willingness-to-pay, market size, statistically valid sentiment — because the agents are not real customers. The reliable move is to use it to sharpen and prioritize real research, then let real customers confirm.

Can I replace user interviews with AI simulation?

No — and you should not. AI simulation and user interviews answer different questions: simulation explores the reaction space quickly and cheaply; interviews tell you what real people actually say and do. The best practice is to simulate first to decide which interviews are worth running, then run them. Simulation narrows the questions; real interviews provide the truth.

How do I get directional feedback fast and cheap?

A simulation returns a directional read in 5–10 minutes for a few dollars: which angle resonates, the main objections, and how sentiment splits. That is far faster and cheaper than recruiting a panel. Just hold it as directional — the value is speed and breadth for early decisions, with real research reserved for the calls that matter most.

Which content angle or landing-page message should I test first?

Run your candidate angles as variants and let the simulation rank which is most likely to engage the described audience and why. The output tells you where to point your first real A/B test rather than guessing. It is a prioritization tool — it estimates the most promising angle to validate, not the guaranteed winner.

How is AI simulation different from real surveys?

A survey collects stated answers from real people at one point in time; a simulation explores how modeled personas interact and react over several rounds, surfacing objections and dynamics a survey question might miss. Surveys give you real (if shallow) data; simulation gives you fast, deep hypotheses. They are complementary — simulate to find the questions, survey to answer them.

How do I decide what’s worth spending real research budget on?

Use a simulation as triage: run the ideas or messages you are considering, see which surface the strongest reactions or the riskiest objections, and spend your real research budget there. It turns “we should research this” into a ranked list of what to validate first — a directional prioritization, confirmed by the real research it points you toward.
