Google has announced an experimental AI-powered code agent called “Jules” that can automatically fix coding errors for developers. Jules was introduced today alongside Gemini 2.0, and uses the updated Google AI model to create multi-step plans to address issues, modify multiple files, and prepare pull requests for Python and Javascript coding tasks in GitHub workflows.
Microsoft introduced a similar experience for GitHub Copilot last year that can recognize and explain code, alongside recommending changes and fixing bugs. Jules will compete against Microsoft’s offering, and also against tools like Cursor and even Claude and ChatGPT’s coding abilities. Google’s launch of a coding-focused AI assistant is no surprise — CEO Sundar Pichai said in October that more than a quarter of all new code at the company is now generated by AI.
“Jules handles bug fixes and other time-consuming tasks while you focus on what you actually want to build,” Google says in its blog post. “This effort is part of our long-term goal of building AI agents that are helpful in all domains, including coding.”
Developers have full control to review and adjust the plans created by Jules, before choosing to merge the code it generates into their projects. The announcement doesn’t say that Jules will spot bugs for you, so presumably it needs to be directed to a list of issues that have already been identified to fix. Google also says that Jules is in early development and “may make mistakes,” but internal testing has shown it’s been beneficial for boosting developer productivity and providing real-time updates to help track and manage tasks.
Jules is launching today for a “select group of trusted testers” according to Google, and will be released to other developers in early 2025. Updates about availability and how development is progressing will be available via the Google Labs website.
