Documentation
Welcome to Diffie docs
Diffie is an AI agent that generates and runs end-to-end browser tests from plain English. You describe a flow, Diffie produces Playwright code, runs it in a real browser, and hands back a video recording of the result. These docs show you how to install Diffie into your workflow and wire it into your CI.
