Jules

What is Jules?

Jules is an autonomous coding agent from Google that handles routine development tasks such as bug fixes, version bumps, test writing, code review help and feature work. It runs asynchronously, so you assign work and review the result later.

Key capabilities of Jules

• Bug fixing: resolves issues from a prompt or the jules label on GitHub issues
• Test creation: writes tests for your code
• Version bumps: routine dependency updates
• Feature building: implements described features
• Plan review: shows a plan and a diff for approval before changes
• GitHub pull requests: approved changes become a PR

How Jules works

You pick a GitHub repository and branch and give instructions. Jules clones the repo to a cloud VM, builds an execution plan with Gemini, shows a diff for your approval, and turns approved changes into a pull request. The vendor cites Gemini 3 Pro for planning and Gemini 2.5 Pro on the free tier.

Who uses Jules?

Developers who want to delegate chores to an agent while they focus on higher-value work.
