AI in market research refers to the use of methods such as language models and machine learning across the research process, from study design through data collection and analysis to the simulation of respondents.
AI is changing market research in many places at once. Most applications make existing steps faster; some change where the data comes from.
Many AI applications speed up work that used to be manual: drafting questionnaires and discussion guides, moderating and transcribing interviews, coding open answers, summarising results. Research shows that the combination of researchers and language models can increase efficiency and quality (Arora, Chakraborty & Nishimura 2025). Here the data source remains the real person, and the AI works with their answers.
A second group of applications replaces the data source: synthetic respondents, AI personas, digital twins. Here the answer itself is generated. This distinction is central to assessing a study. A language model reflects what people have said and written. The open question is whether people choose a new offer. Their behaviour answers that.
What is mainly sped up is exploration, preparation and analysis. What remains open is the validation of new offers. Even studies that credit synthetic respondents with high agreement measure them against surveys, not against behaviour. There is also a side effect: AI agents can complete online surveys themselves and pass 99.8% of attention checks in doing so (Westwood 2025). When a coherent answer can no longer be relied on to come from a human, observed behaviour gains weight.
A consumer goods manufacturer is planning a new product line. AI creates an overview of needs from social media data, formulates 30 concept ideas and has synthetic respondents pre-rate them. A survey of real people narrows these down to five concepts and provides motives. Three of them go into a behavioural test as realistic offers with a price. Within a few weeks, measured purchase intent per variant is available, on the basis of which management decides on the investment.
Synthetic research is the part of AI in market research that generates answers instead of collecting them. Hybrid research describes workflows in which synthetic data, surveys and behaviour each have a clear role. In a Horizon test, the signal comes from real people who see a realistic offer; nothing is sold.
How well AI applications work depends heavily on task, category and language, and the field is changing fast. Statements about individual methods date accordingly. Automated analysis still needs human review, and figures should come from traceable calculations. The behavioural test, on the other hand, is slower than a simulation and limited to a few variants; it belongs at the end of the funnel, not at the beginning.

In preparation, exploration and analysis: discussion guides, coding of open answers, summaries and pre-selection from many ideas.
Partly, for some exploratory questions. For decisions about new offers, data from real people provides the evidence, and for the choice itself, their behaviour.
AI agents can complete surveys and pass attention checks. This makes it harder to ensure that an answer comes from a human.
