Jules AI is an autonomous AI coding assistant developed by Google that works asynchronously in the background. Unlike traditional code-completion tools or co-pilots, Jules AI operates independently to complete entire tasks such as writing tests, fixing bugs, building new features, and updating dependencies. It's powered by the Gemini 2.5 Pro model and designed to handle complex, multi-file changes while integrating seamlessly with GitHub workflows.

Jules AI integrates directly with GitHub, cloning your repositories to a secure Google Cloud VM. When you prompt Jules AI with a task, it analyzes your code, formulates a plan, and presents it for your review. After you approve the plan, Jules AI implements the changes and creates a pull request. This workflow ensures you maintain control while benefiting from autonomous assistance, with all changes visible and reviewable before being merged into your codebase.

Jules AI can perform a variety of coding tasks including: writing comprehensive test suites for existing code, identifying and fixing bugs with detailed explanations, building new features based on specifications, and safely updating dependencies while maintaining compatibility. It's capable of handling complex, multi-file changes and can work on multiple tasks concurrently, allowing developers to focus on more critical aspects of their projects.

As of May 22, 2025, Jules AI is in public beta and available worldwide where the Gemini model is supported. During this beta phase, it's free to use, though usage limits apply. You can check if Jules AI is available in your region on Google's availability regions page. Full details about access and usage limits can be found in the official Jules documentation. Future pricing is expected to be announced when the product exits the beta phase.

Jules AI prioritizes privacy and security by operating in a secure cloud environment and not training on private code. Your data remains isolated within the execution environment, and Jules AI is designed to be private by default. This approach ensures that your proprietary code and intellectual property are protected while still benefiting from the advanced capabilities of the AI assistant.

While tools like GitHub Copilot focus primarily on real-time code suggestions and completions, Jules AI takes a more autonomous approach by handling entire tasks from start to finish. Jules AI is powered by Google's Gemini 2.5 Pro model and is designed to work asynchronously in the background, presenting complete solutions for review rather than line-by-line suggestions. This positions Jules AI as a competitor in the growing market of AI coding assistants, with a specific focus on autonomous task execution rather than just code completion.

During its initial closed preview in December 2024, Jules AI was aimed at trusted testers for tasks like bug fixes and pull requests in Python and JavaScript. Now in public beta, Jules AI is likely capable of working with a broader range of programming languages and frameworks, leveraging the capabilities of the Gemini 2.5 Pro model. For the most current information on supported languages and frameworks, refer to the official Jules documentation.

Jules AI offers several unique features including audio summaries of recent commits, parallel execution of multiple tasks, and the ability to work directly with real codebases without requiring a sandbox environment. It also provides visible workflows with detailed plans, reasoning, and diffs, allowing developers to understand the AI's approach and decision-making process. Additionally, Jules AI supports user steerability, enabling developers to modify plans and review changes before implementation.

Jules AI was initially launched in closed preview in December 2024, powered by Gemini 2.0, and aimed at trusted testers for specific coding tasks. It then entered public beta on May 21, 2025, as announced during Google I/O 2025. This release marked a significant step in Google's efforts to enhance development workflows with AI. Future development and a full release with pricing details are expected as the platform matures beyond the beta phase.

No, there is a potential point of confusion worth noting: Google's Jules AI coding assistant is completely unrelated to a separate company called JulesAI, which focuses on automating tasks for trading recycled materials. These are two distinct entities with different purposes and should not be conflated. Google's Jules AI is specifically designed as an autonomous coding assistant for developers.
