## How Minds actually works

Minds is a synthetic market research platform built to provide marketing, insights, product, and innovation teams with fast, validated, and highly specific consumer feedback. The core philosophy of Minds is that synthetic research is only as good as the data that anchors it. Instead of relying on generic artificial intelligence prompts or simple large language model roleplay, Minds allows users to build highly calibrated, validated personas, which are called Minds, and assemble them into custom panels. These panels are designed to simulate a specific target audience, whether that means high-income millennial parents in Germany, enterprise IT decision-makers in the United States, or niche subscription customers from a company's internal database. Because the platform runs entirely in the browser, there is no complex setup or developer infrastructure required, allowing teams to go from a research brief to actionable insights in under an hour.

The underlying simulation and validation pipeline is what sets Minds apart from generic market research tools. To ensure that the synthetic personas act and respond like real human consumers, Minds anchors its audiences in real-world data. This data anchoring process can ingest proprietary customer relationship management (CRM) data, historical brand surveys, classic market studies, and precise demographic anchors. This ensures that when you ask your custom panel to evaluate a new product concept, a marketing message, a packaging design, or a pricing model, the responses are grounded in actual consumer behavior rather than statistical hallucinations. To guarantee scientific rigor, Minds validates its outputs against real human panel answers and official reference sources, such as the US Census, the Bureau of Economic Analysis, Eurostat, and other national statistics agencies. Through this continuous calibration, Minds reaches an average of 85 to 95 percent agreement with traditional human panels, giving researchers the confidence to make high-stakes business decisions.

Once a custom panel is assembled, Minds supports a rich variety of workflows that deliver both quantitative results and qualitative, interview-style artifacts. Users can run structured concept tests, message variations, pricing analyses, and packaging evaluations, receiving statistically sound quantitative metrics. Simultaneously, users can initiate multi-persona chat rooms to observe simulated focus groups or conduct deep-dive qualitative interviews with individual Minds. This hybrid approach provides researchers with the numerical validation they need alongside the deep, narrative reasoning that explains why a consumer feels a certain way. Furthermore, Minds is built to meet the strictest global data privacy standards. The platform is hosted entirely on secure EU servers and processes no personal data, ensuring that enterprise insights teams can conduct research without risking compliance violations. With a highly accessible pricing model that starts with a free tier, a Premium plan at about 39 euros per month, and seat-based Team plans at about 79 euros per seat per month, Minds makes robust synthetic research accessible to organizations of all scales.

## How sampl.space actually works

sampl.space is a specialized synthetic survey platform designed primarily for academic researchers, public policy analysts, and survey methodologists who need to test hypotheses and validate survey instruments. Unlike platforms that allow users to build custom, proprietary audiences from scratch, sampl.space takes a fixed, statistically grounded approach. The platform maintains a permanent, nationally representative bank of 3,505 synthetic personas that collectively reflect the adult population of the United States. These personas are not fictional characters invented by artificial intelligence. Instead, they are statistically derived from the General Social Survey (GSS), which is one of the most respected and rigorous social science datasets in existence. Conducted by NORC at the University of Chicago since 1972, the GSS tracks hundreds of demographic, attitudinal, and behavioral variables over decades, capturing authentic patterns in how real Americans respond to complex social, political, and economic questions.

The workflow inside sampl.space is built to replicate the experience of traditional survey administration. Users begin by drafting their survey questions, scenarios, or experimental conditions within the platform's built-in editor, much like they would in a standard online survey tool. After defining the questions, users can choose to run the survey against the entire database of 3,505 personas or filter the audience to target specific subgroups. The platform allows users to filter the synthetic respondents by key demographic variables, including age, political affiliation, religious beliefs, education level, and geographic region. When the study is launched, each selected persona acts as an independent agent with its own unique identity file and worldview, reasoning through the provided scenario based on its statistically modeled background. The platform then generates results in minutes, providing detailed demographic breakdowns of the responses alongside individual reasoning transcripts that explain the logic behind each virtual respondent's choice.

This GSS-grounded approach makes sampl.space highly effective for academic research, political framing studies, and general social attitude tracking. The platform operates on a usage-based pricing model, offering a pay-per-response rate starting at 0.15 dollars per response, which drops to 0.10 dollars for volumes exceeding 1,000 responses, alongside per-study pricing options starting at 99 dollars and monthly subscriptions from 499 dollars. However, this specialized methodology also introduces clear limitations for commercial applications. Because the underlying personas are built exclusively on GSS data, the platform is restricted to the U.S. general public. It cannot model niche commercial audiences, international consumer markets, or highly specific B2B professional roles, such as specialized software engineers or European procurement managers. Additionally, because these synthetic personas represent historical survey respondents rather than active consumers, they cannot perform behavioral tasks, evaluate specific app user interfaces, or provide feedback on proprietary, brand-specific customer experiences.

## When to choose Minds

Minds is the clear choice when your research requires highly specific, custom, or company-specific audience simulation. In commercial marketing, product development, and brand strategy, target audiences are rarely as broad as the general U.S. public. Instead, brands need to understand the attitudes, preferences, and objections of highly precise consumer segments, such as premium subscription holders from their own CRM, historical survey respondents, or specific demographic cohorts in international markets. Minds excels in these scenarios by allowing you to anchor your panels in your own proprietary data and classic market studies. This level of customization ensures that the simulated feedback reflects your actual target buyers rather than a generic public average, allowing marketing and insights teams to run highly accurate concept, message, pricing, packaging, and positioning tests.

Additionally, Minds is the superior option if your team needs to support richer, more interactive qualitative workflows. While traditional survey platforms focus on flat, quantitative responses, Minds allows you to assemble your calibrated personas into multi-persona panels for real-time focus group simulations. This allows product and innovation teams to ask open-ended questions, run follow-up queries, and extract detailed, interview-style qualitative artifacts in under an hour. Combined with strict data privacy compliance, secure EU hosting, and a highly accessible subscription model that starts with a free tier, Minds provides a scalable, enterprise-ready environment designed specifically for the fast-paced needs of commercial brands and marketing agencies.

## When to choose sampl.space

On the other hand, sampl.space is the ideal choice when your research is focused on U.S. public policy, academic social science, or broad sociological attitude tracking. If you are a social scientist, academic researcher, or political strategist looking to validate a survey instrument, test how different framing options affect public opinion, or analyze broad demographic trends across the American public, the GSS-calibrated database of 3,505 personas provides an incredibly valuable resource. Because these personas are rooted in over fifty years of rigorous social science research from NORC at the University of Chicago, they offer a highly reliable and statistically calibrated environment for testing general public attitudes without the high cost of human recruitment. For early-stage academic hypothesis testing and broad sociological surveys where custom commercial audiences are not required, sampl.space offers a specialized and methodologically sound solution.
