Jules is Google's asynchronous coding agent: pick a GitHub repo and branch, describe the task, and it clones the code to a cloud VM, plans, makes the change and opens a PR. Free plan includes 15 tasks per day.
What is Jules?
Jules shows its plan before executing and returns a diff for approval. You can also assign tasks by adding a 'jules' label to a GitHub issue.
Higher daily task limits come with Google AI Pro and Ultra subscriptions.
