Anamnesis: Open-Source Platform for Backstory-Conditioned Survey Simulation

Jul 14, 2026

Anamnesis is an open-source platform that enables large-scale survey simulation using large language models (LLMs), designed to be accessible for non-technical users. The system leverages structured narrative backstories to condition responses and supports multimodal surveys, including image and audio. Case studies demonstrate that Anamnesis produces opinion distributions that more closely align with real-world survey data compared to standard persona-prompting methods.

Why it matters: This platform offers a transparent and reproducible alternative to proprietary survey simulation tools, allowing researchers to prototype and stress-test survey instruments without relying on human subjects.
