What Junie can do for you

Provide a seamless coding experience

Getting started with the AI agent is simple. Install it in your IDE and begin with small tasks that fit seamlessly into your workflow – no dramatic changes required. This approach ensures that your new way of working is empowering, not disruptive, whether you code in Java, Python, JavaScript, Go, etc.

Discover efficient solutions

Junie understands the structure, logic, and relationships in your code. When you delegate a task to the AI agent, it finds the right places to work, the right tools to use, and the best path forward.

Propose an execution plan

Once Junie has explored the project, it will provide a cohesive plan for completing the task. Junie uses Anthropic (Claude Sonnet) and OpenAI (GPT-5) LLMs for the best developer experience, both in coding and reasoning.

Adjust to the task at hand

Use Code mode to execute tasks, with Junie writing and testing the code for you. Switch to Ask mode, to pose questions, collaborate on plans, and brainstorm features and improvements.

Perform inspections you can rely on

When Junie updates your code, it uses the power of your IDE to make sure every change meets your standards. Built-in syntax and semantic checks keep your code clean, consistent, and production-ready. With AI Assistant, code completion, and other features, Junie offers a full AI experience in the IDE that you already trust.

Run tests to keep your project state green

Junie runs code and tests as needed to reduce warnings and compilation errors. After making changes, Junie verifies that everything runs smoothly so that you can focus on building instead of debugging.

Intelligent collaboration on complex tasks

Focus on the big picture while Junie takes care of the routine work. Review, refine, and stay in control. Junie’s here to support you.
