Jules is Google's AI coding agent powered by Gemini. It integrates with GitHub workflows to autonomously handle coding tasks—fixing bugs, writing tests, implementing features, and submitting pull requests. Jules runs in a cloud VM with its own development environment, understanding project context and dependencies to produce code that fits naturally into existing codebases.
