Academic questionnaire pilots
Check reliability, item quality, and dimension structure on a new or adapted scale before recruiting real participants.
Use Cases
Pre-Test Before You Field It
Brand & concept pre-tests
Directionally screen purchase intent, uniqueness, and price sensitivity on a concept or ad copy before spending fieldwork budget — not a replacement for real consumer research.
Questionnaire QA for survey firms
Run a client's draft instrument past simulated respondents to catch confusing wording or a weak scale before it goes to a real panel.
How It Works
From Questionnaire To Report In Three Steps
Define your questionnaire
Bring an Excel workbook or a JSON spec — or let your AI agent build one from a plain-language description, validated against the EZPsych schema before you spend a single credit.
Virtual personas answer
LHS-sampled respondent profiles, each with a generated life-story narrative, work through every item the way a matching participant might.

Reliability, construct validity, dimension structure, and item quality — with optional item-effect and question-order monitoring included.

A Free Public API For Autonomous Research Agents
A machine-readable entry point and a free, no-auth validation endpoint let an agent design and check an experiment before a human needs to sign in.
