Live Eurostat data
NUTS-2 regional population shares and EU-SILC income quintiles, with data provenance recorded per axis.
Samplio simulates how consumer segments react to your copy, using LLM personas grounded in real Eurostat market structure — region × income × value orientation. Built for brands and agencies. Commercial research only.

Message test result
“Neue Hafermilch: gleicher Geschmack, 30% weniger Verpackung.”
de-consumer · 10.000 agents · [email protected]/de
“Endlich eine Hafermilch, die nicht nur gut schmeckt, sondern auch aktiv zur Müllreduzierung beiträgt – das ist ein wichtiger Schritt in die richtige Richtung.”
“Der gleiche Geschmack ist entscheidend, und weniger Verpackung ist ein willkommener, praktischer Vorteil.”
“Es ist gut zu hören, dass die neue Hafermilch trotz weniger Verpackung den gleichen vertrauten Geschmack behalten soll.”
“Für uns als preisbewusste Konsumenten ist aber entscheidend, ob sich dies auch im Preis niederschlägt oder zumindest das Preis-Leistungs-Verhältnis verbessert.”
SYNTHETIC SIMULATION — A real run on this engine (gemini-2.5-flash, German audience simulated in German), reproduced verbatim. It is a model-based estimate on a synthetic population, not a survey of real respondents. The PLACEHOLDER stamp is the engine's own: the value-orientation axis is not yet calibrated, so treat splits on that axis as directional.
Why Samplio
NUTS-2 regional population shares and EU-SILC income quintiles, with data provenance recorded per axis.
Dirichlet + IPF + K-Means build the synthetic population; segments emerge from clustering, not from hand-picked stereotypes.
Every LLM call leaves an audit record (model, prompt hash, duration) — traceability designed for the EU AI Act.
How it works
No panel recruitment, no fieldwork, no waiting for a field institute.
A country pack simulated in its own language, a macro region, or the EU-27 average.
Audience scope
One message, 2–5 variants on the identical audience, or a conditional survey.
Message
“Neue Hafermilch: gleicher Geschmack, 30% weniger Verpackung.”
Reaction distribution per segment plus a verbatim “voice of the segment”. Print or save as PDF — watermarked.
Test modes
One engine behind every surface — the web app, the CLI and the API share the same guardrails and the same composite logic.
One consumer-facing message; every audience segment reacts with a full response distribution plus a short “voice of the segment” summary.
All variants run on the identical synthetic audience — same seed, only the copy differs — with a ranking by the reaction you care about.
Up to 12 single-choice questions with skip logic. Follow-up reach is computed deterministically in code, never estimated by the model.
Coverage
29 EU markets, each simulated in the audience's own language (8 languages).
Western, Northern, Southern, Central and Eastern Europe plus the EU-27 mean — documented, editable groupings for directional reads.
A macro-region query runs each member country separately and combines the results population-weighted. The weighting math lives in code, not in the LLM.
Method honesty
The engine is built so it cannot overstate what it knows.
Every result carries a SYNTHETIC SIMULATION watermark — on screen and in print. This is model-based estimation, not a survey of real respondents.
Accuracy figures appear only once they are measured against a sourced real-world case corpus. Until then, none are shown — anywhere.
Axes without real calibration data are mechanically marked, and custom surveys are always directional. Instead of a misleading ±% margin of error (which does not apply to synthetic agents), Samplio reports re-run stability.
Election and political-campaign use is prohibited on every surface and rejected at the engine boundary — an 8-language keyword screen plus an LLM classifier enforce the terms of service mechanically.
