oTree experiments without coding

Introducing OTAI, an AI-powered system that lets you build sophisticated behavioral experiments through a chat interface.

Get Started
OTAI Interface

Use AI in a guided and controlled way

Quality research requires precision and knowing what you are doing. Current AI coding tools generate too much uncontrolled output that destabilizes your work.

OTAI is not just an AI wrapper. Our LLM is trained with oTree code, and is just one component of a larger architecture that ensures reliability and correctness. The LLM is not allowed to write code directly, but rather gives instructions to our system, thus preventing hallucinations.

Fast

Other AI tools may generate promising-looking output quickly, but then get stuck fixing problems while introducing new ones. OTAI produces consistent progress, reaching the finish line faster.

Convenient

Use OTAI directly in your browser. All changes are automatically synced to a folder on your computer. You don't need to install anything other than oTree.

Key Features

Built for you

OTAI is custom built for behavioral researchers. It was written by the author of oTree and is 100% integrated with oTree's designs and workflows. It will guide you the right way toward a working experiment.
