What Jules is

Jules is an autonomous coding agent for repository tasks such as fixing bugs, adding documentation, updating apps, and building features. After a user connects GitHub and chooses accessible repositories, Jules clones a repository into a cloud virtual machine and proposes a plan for approval before changing code. It then presents a diff and creates a pull request for review and merging. Jules can index codebases and use a terminal. It is language agnostic and works best with JavaScript or TypeScript, Python, Go, Java, and Rust. It can detect failed GitHub Actions checks on its pull requests, work on a fix, and resubmit the pull request. MCP connections include Linear, Stitch, Neon, Tinybird, Context7, and Supabase. Its REST API is in alpha for automating workflows such as bug fixes and code reviews. Jules runs code in an internet-connected cloud virtual machine; Google advises reviewing code and keeping secrets out of repositories. Jules says private repository content is not used to train models. A free plan is listed, with paid plans available through Google AI Plans only to individual Google Accounts ending in @gmail.com.
