What is Jules?
Jules is an autonomous coding agent by Google. You select a GitHub repository and branch, write a prompt describing the task, or assign it by adding the "jules" label to a GitHub issue. Jules then clones the repository to a cloud virtual machine, builds a plan using Gemini models, and carries out the work while you focus on other code.
When the work is finished, Jules shows a diff of the changes so you can review and approve the edits, then creates a pull request on GitHub. The example on the homepage shows upgrading Next.js to v15 and moving a project to the app directory structure. Typical tasks listed include bug fixing, version bumps, writing tests, fixing existing code and building features.
