The era of writing code for behavioral experiments is over.

AI does it 10 times as fast, with better accuracy.

Get Started

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

Conventional AI coding tools oTree AI
Conventional AIGenerate too much uncontrolled output that destabilizes your work. oTree AIHighly trained in oTree code and understands well how to build a working experiment.
Conventional AIGenerate promising-looking output quickly, but then get stuck fixing problems while introducing new ones. oTree AIProduces consistent progress, reaching the finish line faster.
Conventional AIIf you're not an expert developer who can catch the bugs that the LLM often slips in, your chances of success go way down. oTree AISuitable for all experience levels.
