Junie, the AI coding agent by JetBrains

Overview

Junie is an AI coding agent developed by JetBrains that operates directly inside JetBrains IDEs. It takes coding tasks delegated by the developer and works through them autonomously inside the development environment.

Unlike chat-based AI assistants that only suggest code, Junie acts as an agent that can perform multi-step development workflows. It is designed for developers already using JetBrains tools who want to offload routine coding work.

Key Benefits

• Delegate coding tasks and let the AI agent handle the execution while you focus on higher-level results.
• Operates natively inside JetBrains IDEs, meaning no context switching or copy-pasting code to external tools.
• Built by JetBrains, the same company behind IntelliJ IDEA and the broader JetBrains IDE ecosystem.

How It Works

You describe a coding task inside your JetBrains IDE, and Junie works through it autonomously as an agent within the same environment. The AI reads your project context, executes steps, and produces results directly in your codebase.

Use Cases

• Full-stack web developers using IntelliJ-based IDEs who want to automate repetitive coding patterns.
• Backend engineers working in Java, Kotlin, or other JVM languages who need help with boilerplate generation.
• Team leads using JetBrains Team Tools who want to delegate routine refactoring to an AI agent.
