How to Use Jules in 2026: Step-by-Step Guide
Google's asynchronous AI coding agent that works on GitHub repositories in the background — fixing bugs, implementing features, and raising pull requests without interrupting the developer.
Jules is Google's asynchronous AI coding agent, announced at Google I/O 2025 and built on Gemini 2.5 Pro. It operates on GitHub repositories autonomously — the developer assigns a task, Jules works on it in the background, and submits a pull request when complete.
What Jules Does Well
Asynchronous operation is Jules's defining characteristic. Unlike in-editor AI assistants (Copilot, Cursor) that require the developer to be present, Jules works in the background on a task while the developer focuses on other work. Assign Jules a bug fix or feature, and come back to a completed pull request.
Full repository context gives Jules a complete understanding of the codebase rather than just the currently open file. It can trace a bug through multiple files, understand existing patterns and conventions, and write new code that fits naturally into the established architecture.
GitHub-native workflow makes the integration seamless for teams already on GitHub. Jules creates branches, commits changes with descriptive messages, and raises pull requests that go through the team's normal review process — the AI's work is treated like any developer's contribution.
Multi-step planning handles tasks that require more than a single edit. Jules creates a plan, executes it step by step, and can self-correct when test runs fail or when intermediate steps reveal new requirements.
Free during beta as Jules builds toward general availability. Google has not announced production pricing.
Who Jules Is For
Jules targets developers who want to offload well-defined, lower-complexity tasks — bug fixes, documentation updates, test generation, minor refactors — to an AI agent that works autonomously. It integrates with the Google IDX development environment and GitHub.
What You'll Need
- A Jules account (free to create)
- A modern web browser or the Jules app
Getting Started
Create Your Account
Visit https://jules.google and sign up for a free account. You'll need an email address to register.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Jules supports async-coding, github-integration, pull-request-generation, bug-fixing, autonomous-agent — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Jules what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
Common Use Cases
Programming & Code
AI assistants focused on writing, debugging, and explaining code across programming languages.

- Responses seem generic or unhelpful
- Add more context to your prompt. Specify the audience, tone, length, and format you need. Try starting over with a clearer description of your goal.
- The tool isn't responding or is slow
- AI chatbots can experience high traffic. Refresh the page and try again. Check the service's status page if issues persist.
- Output is too long or too short
- Explicitly specify the length: "in 100 words," "as a brief summary," or "in detail with examples."
