Is Jules free to use?

Yes — Jules offers a free base tier with a daily task limit and a set number of concurrent tasks. Higher-capacity paid tiers are available through Google subscriptions, offering more daily tasks, more concurrency, and access to priority model variants.

Which programming languages does Jules support?

Jules is optimised for JavaScript, TypeScript, Python, Go, Java, and Rust. It is also broadly language-agnostic, so other languages can work depending on how the project's VM environment is configured.

How does Jules fit into an existing GitHub workflow?

Jules integrates directly with GitHub. You can trigger tasks by applying a 'jules' label to a GitHub issue, by selecting a repository and branch in the Jules web interface, or programmatically via the Jules API. Jules then creates a pull request with the changes for your team to review and merge.

Does Jules train its models on my private code?

No. Jules explicitly does not use your private repository content to train its models. Each task runs in an isolated cloud VM, and your data stays within that execution environment.

What kinds of tasks is Jules best suited for?

Jules excels at discrete, well-scoped tasks: fixing bugs, writing unit tests, updating dependencies, adding documentation, bumping package versions, and implementing defined features. It does not currently support long-running processes such as local development servers inside its setup scripts.
