by Google
Google's proactive AI coding agent that scans repos for issues and proposes fixes autonomously, powered by Gemini.

Unlike reactive agents that wait for commands, Jules scans repositories for signals like TODO comments, open issues, and code quality problems, then proposes fixes and improvements without explicit requests. It has completed over 140,000 code improvements. Jules operates asynchronously, reviewing and improving code in the background while developers focus on feature work. Integrated with GitHub for PR creation and code review workflows.
