Jules

Jules is a coding agent from Google that works on tasks in the background. You give it a repository and a prompt, and it returns changes as a pull request for you to review.

Jules imports your GitHub repositories and creates a branch for each task. It clones the code into a cloud virtual machine, writes a plan, and waits for your approval before it makes edits. When the work is done, it shows a diff and opens a pull request. The site says the planning step uses Gemini 3 Pro.

• Works on GitHub repositories and chosen branches
• Shows a plan you can approve before changes start
• Runs existing tests or writes new ones in the cloud VM
• Shows a diff for review before a pull request is opened
• Can be assigned a task from a GitHub issue label

Developers with a backlog of small chores, such as dependency updates, test fixes or migrations, will get the most from it. Teams that want to hand routine work to an agent while keeping review in their own hands will also find it useful.

Jules is offered in several plans, which the site lists on a separate page. It can be used from the web, from the command line or through an API. Because each task runs in a cloud VM, your code is copied there, so check the data terms before you use it with private projects.
