What is Jules?

Discover how Jules can enhance your workflow

Jules is an experimental coding agent from Google designed to take on the tasks you do not want to do. After you authenticate and connect a repository and branch, you describe the job and Jules plans edits, runs changes, and raises a pull request with a summary. It focuses on practical throughput, like fixing failing tests, version bumps, documentation updates, small features, and tidy up work that clutters backlogs. The agent understands your codebase context and works asynchronously while you continue other tasks. Docs describe setup, permissions and first run guidance, while the main site highlights common jobs and a simple prompt first workflow. For now Jules is positioned as an experiment with evolving limits and access, so teams should evaluate it on non critical branches before adopting more widely.
