Cloze: An Open Research Platform for Studying Human-AI Conversations in Mental Health Contexts

Cloze is an open-source web platform designed for controlled studies of human-AI conversations specifically in mental health research. It allows researchers to configure interactions with various large language models, including those from OpenAI, Anthropic, and Google, while ensuring consistent data capture and safety constraints across studies. This platform addresses the limitations of existing consumer LLMs by providing a unified environment for experimental control, making it a valuable tool for building an evidence base on human-AI interactions in mental health contexts.
