Minds vs Synthetic Users: AI Research Panels Compared

Synthetic Users and Minds both use AI personas to replace slow, expensive human research. But they were built for different jobs, serve different teams, and produce different shapes of output. This guide breaks down the real differences so you can pick the right tool for how your team actually works.

What Synthetic Users Does

Synthetic Users is built around qualitative product discovery. The platform lets product managers and UX researchers run synthetic depth interviews with AI users, producing the kind of qualitative insight you would normally get from a five-user discovery study. The workflow mirrors discovery research: define your target user, set the research question, run interviews, synthesize themes.

The strength of Synthetic Users sits in that focused workflow. If your job is product discovery and your stakeholders expect interview-shaped output (themes, quotes, mental models), the platform delivers that shape cleanly. The trade-off is breadth. Synthetic Users is not built for cross-team marketing panels, message testing across segments, or research that lives outside the product-discovery rhythm.

Pricing is subscription self-service. Synthetic Users is positioned for product teams and UX researchers as a same-day discovery research replacement.

What Minds Does

Minds is a self-serve AI panel platform where you build minds of your customer types and run structured Groups across 5 to 50+ minds in a single session. Four built-in panel types cover the common research jobs: concept testing, message testing, segmentation, and journey mapping. You can also run one-to-one conversations with a single mind for deeper qualitative depth.

The platform is designed for direct use by marketing, product, sales, and research teams. A marketing manager can test five message variants across three segments in an afternoon. A product manager can run a concept test before lunch. A sales team can pressure-test objections with a synthetic buyer panel. A research lead can build a journey map across the full customer lifecycle.

Minds is validated at 80 to 95 percent accuracy against historical human-panel data, depending on the persona and use case. The platform is built in Germany, GDPR-native, with DPA available. Plans start at 5 EUR per month for Lite, 20 EUR for Teams, 30 EUR for Premium, and 15,000 EUR per year for Enterprise.

Core Differences

Shape of Output

Synthetic Users produces interview-shaped output: depth interviews you can read like real qualitative research. The format is familiar to product and UX teams used to discovery research.

Minds produces panel-shaped output: aggregated responses across multiple synthetic minds, with optional follow-ups and one-to-one depth conversations on top. The format covers both qualitative depth and quantitative-flavored aggregation across segments.

Who Uses It

Synthetic Users is built for product managers and UX researchers as a discovery research replacement. The persona of the tool reads "PM running discovery."

Minds is built for marketing, product, sales, and research teams. The persona reads "anyone on the team who needs customer intelligence." Marketing managers run message tests. Product managers run concept tests. Sales leaders pressure-test objections. Agency strategists run client panels.

Validation

Synthetic Users does not publish accuracy benchmarks against real human responses. The platform's validation story rests on its workflow and methodology rather than published numbers.

Minds publishes 80 to 95 percent accuracy benchmarks against historical human-panel data, depending on the persona and use case. The validation story is "here are the numbers" rather than "trust the methodology."

Panel Breadth

Synthetic Users is built for discovery interviews, typically with a small number of synthetic respondents per study. The format prioritizes depth over breadth.

Minds Groups run across 5 to 50+ minds per panel, with the ability to scale further on Enterprise plans. The format covers both depth (one-to-one mind conversations) and breadth (aggregated panel responses across segments).

Pricing and Commitment

Synthetic Users is subscription-based, positioned for product teams.

Minds starts at 5 EUR per month for Lite, with Teams at 20 EUR, Premium at 30 EUR, and Enterprise from 15,000 EUR per year. No implementation project, no professional services dependency, no minimum commitment beyond a monthly subscription.

Detailed Comparison

When to Choose Synthetic Users

Choose Synthetic Users when your primary job is product discovery, when your stakeholders expect interview-shaped qualitative output, when your team workflow already mirrors traditional discovery research, or when you need a tool that drops cleanly into a product-discovery rhythm without retraining.

When to Choose Minds

Choose Minds when you need cross-team panels that marketing, product, sales, and research can all use. When you need both depth (one-to-one mind conversations) and breadth (panels across 5 to 50+ minds). When your stakeholders want published validation benchmarks. When your budget needs to start at 5 EUR per month rather than a subscription tier. When you want the same tool to serve concept testing, message testing, segmentation, and journey mapping.

The Bottom Line

Synthetic Users and Minds solve overlapping problems with different shapes. Synthetic Users is the focused discovery-interview replacement for product teams. Minds is the cross-team panel platform with validated benchmarks for marketing, product, sales, and research.

For most teams evaluating both, the practical question is: do you need a discovery-interview replacement, or a panel platform that covers the full research surface?
