oTree Hub - Build experiments with AI

The oTree AI Builder is a single platform that can build and run all your behavioral experiments, from surveys, to psychological stimulus-response experiments, to real-time multiplayer games. Build experiments and launch them on our servers, without ever installing any software or coding.

Use AI in a guided and controlled way
