Jules – Google's AI Coding Assistant for Automating Development Tasks

What is Jules?

Jules is an experimental AI coding assistant developed by Google Labs, aimed at automating repetitive coding tasks such as bug fixes, version updates, test creation, and feature implementation. By integrating with GitHub workflows, Jules allows developers to delegate mundane tasks, enabling them to focus on more critical aspects of software development. Built on Google's Gemini 2.5 Pro model, Jules operates asynchronously, processing assigned tasks in the background while developers continue their work uninterrupted.
