Jules
Google's background coding agent that turns GitHub tasks into pull requests.
Group: Coding agents
Jules is Google's asynchronous coding agent. You pick a GitHub repository and branch, write a prompt, and it clones the repository to a cloud VM, shows a plan, then produces a diff and a pull request. You can also assign tasks with a 'jules' label on a GitHub issue.
The decision in plain English
A hands-off coding helper for maintenance work such as version bumps, bug fixes and tests. The site says it shows a plan and a diff for you to approve before the pull request. Daily task limits differ by plan.
Best fit
Developers with GitHub repositories who want routine tasks handled in the background and returned as pull requests to review.
Poor fit
Teams that do not use GitHub, or anyone who needs a published price before committing.
Documented capabilities
Vendor statements, not verified task outcomes.
Permissions and human control
- Jules says it fetches your repository and clones it to a cloud VM, then presents a plan and a diff and creates a pull request. It describes approving the plan and reviewing the diff before the pull request. Vendor statements only; we did not find a separate data-handling page in this check.
Documented controls do not prove that an agent always follows them.
Limits and open questions
- Price per plan not shown on the page we read; listed only as task limits
- Free-tier limit on the page: 15 tasks a day and 3 concurrent tasks
- Works from GitHub repositories (vendor page)
- Described by the vendor; not tested by AgentComparison
Privacy and security
Not checked in depth. We did not read Google's data-handling terms for Jules in this pass, so treat training and retention questions as unknown until you read them.

How to evaluate Jules yourself
- Pick one low-risk task that matches its documented capabilities: plan, diff and pull request workflow on a cloud vm.
- Write the expected output and what counts as failure before you start.
- Connect the minimum access needed, and check approval settings first.
- Run it twice and compare, then review every action it took.
- Check cost after any free allowance. Unknown price is not free.
