What are synthetic respondents?

Synthetic respondents are AI personas that answer research questions in place of real humans. They are built from large-scale public-web research, psychological models, and (for some platforms) connected first-party data. The strongest platforms validate output against historical human-panel benchmarks. Minds reports 80 to 95 percent accuracy against historical data; Aaru reports ~90 percent correlation against EY-validated research.

Which synthetic respondent platform is most accurate?

Two platforms publish validation benchmarks publicly: Minds at 80 to 95 percent accuracy against historical human-panel data, and Aaru at ~90 percent correlation with EY-validated research. Most other synthetic platforms do not publish accuracy numbers, which means accuracy claims need to be tested in your own use case before relying on them for live decisions.

What is the cheapest synthetic respondent platform?

Minds Lite starts at 5 EUR per month. OpinioAI starts at 99 USD per month. Most enterprise synthetic respondent platforms (Evidenza, Aaru, Electric Twin, Lakmoos) sit on annual enterprise contracts. For solo strategists and small teams, Minds is the only sub-monthly-subscription option that includes panel functionality.

Can synthetic respondents replace real human research?

For most marketing decisions, yes, with validation. Synthetic respondents are best used for exploration, concept testing, message testing, and segmentation, where same-day insight matters more than real-respondent provenance. For regulated decisions, deeply sensory product tests, or stakeholder situations that require real human signal, pair synthetic exploration with a smaller real-respondent validation step.

What Synthetic Respondents Actually Do

Synthetic respondents are AI personas that answer research questions in place of real humans. The strongest implementations:

Build personas from deep public-web research (roughly 100x what a typical AI prompt provides)
Layer psychological models over the raw data (Big 5, values, motivations, buying behavior)
Validate outputs against historical human-panel benchmarks
Aggregate responses across multiple personas to produce panel-style distributions

The category divides into three shapes: conversational panels, behavioral simulations, and survey-shaped synthetic respondents.

The Platforms, In Detail

Minds (conversational panels, self-serve)

Builds AI minds of your customer types and runs Groups across 5 to 50+ minds in a single session. Four built-in panel types: concept tests, message tests, segmentation, journey mapping. Validated at 80 to 95 percent accuracy against historical human-panel data. Same-day setup, GDPR-native, German-built. Best for marketing, product, and research teams that need same-day panel insight without a research function.

Aaru (behavioral simulation, enterprise)

Agent-based behavioral simulation. Reports ~90 percent correlation against EY-validated research on consumer decision modeling. Fortune 500 deployment focus, managed-engagement model. Best for enterprise research teams running large-scale behavioral studies.

Evidenza (managed synthetic B2B studies)

Synthetic CMO and senior B2B buyer simulations from former LinkedIn B2B Institute leaders. High-touch managed-engagement model. Best for Fortune 500 B2B marketing teams testing enterprise positioning.

Synthetic Users (discovery-focused)

Synthetic discovery interviews for product teams. Clean workflow oriented around qualitative discovery. Best for product managers and UX researchers running discovery sessions.

OpinioAI (budget synthetic platform)

Synthetic focus groups and surveys from $99 per month. Lowest entry point in the category. Best for startups and agencies experimenting with synthetic data before committing to a heavier platform.

Perspective AI (survey-shaped synthetic respondents)

Synthetic respondents that answer structured surveys, producing survey-instrument-shaped output. Best for insights teams who want synthetic data in survey format for existing reporting workflows.

Electric Twin (consumer audience panels)

Synthetic audiences modeled on consumer media data. Used by major media publishers. Best for consumer brand and media research teams.

Sanctum (pre-launch feature validation)

Narrow product validation focus: "send features to simulated users before real ones." Best for product teams running pre-launch feature validation.

Simile (population-level modeling)

Population-scale synthetic modeling, more academic-flavored. Useful for teams wanting to model market-level dynamics. Best for strategy and consumer insights teams modeling whole markets.

Lakmoos (German industrial research)

German neuro-symbolic AI for industrial verticals: automotive, finance, energy. DACH market focus. Best for DACH enterprises in regulated industries.

How to Choose

Four questions:

What shape of insight do you need? Conversational panel answers (Minds), behavioral simulation outputs (Aaru), survey-instrument responses (Perspective AI), or discovery interview transcripts (Synthetic Users)?

How fast do you need it? Same-day means Minds, OpinioAI, Synthetic Users, Perspective AI, or Sanctum. Days-to-weeks opens the enterprise managed-engagement options.

Who runs it? If anyone on the team should self-serve, use Minds, Synthetic Users, OpinioAI, Perspective AI, or Sanctum. If a research function owns the work, the enterprise managed platforms apply.

What does validation need to look like? If your stakeholders need published accuracy numbers, Minds (80 to 95 percent) and Aaru (~90 percent against EY) are the two with public benchmarks. Others rely on methodology narrative.

For most marketing, product, and research teams in 2026, Minds is the strongest fit. The conversational panels, four panel types, same-day insight, published accuracy benchmarks, and 5 EUR entry point cover the broadest range of common synthetic research jobs.
