Jules

What is Jules?

Jules is an asynchronous coding agent from Google. You connect a GitHub repository and describe a task; Jules works in a secure cloud virtual machine, reads your code, plans changes, edits files and runs tests, then presents a plan and diff for you to approve and publish as a pull request.

Asynchronous means you don't have to watch it work. You hand Jules a task, such as fixing a bug, updating dependencies or writing tests, and continue with other things while it runs in the background.

Jules shows its plan before making changes, so you can adjust the approach, and it provides a summary of what it did. It's powered by Google's Gemini models.

Jules launched in public beta in 2025 and later became generally available with a free tier and higher limits for paid Google AI plans.
