Overview
Junie is JetBrains' AI coding agent, designed to be the most cost-efficient way to automate software development tasks. It runs locally on Mac, Linux, or Windows and integrates directly with JetBrains IDEs, leveraging the proven IntelliJ IDEA engine for deep code understanding. Developers love Junie because it supports 10+ top-performing models via Bring Your Own Key (BYOK), letting you plan on a powerful model and implement on a fast one for the same quality at a fraction of the cost.
Unlike rigid single-model assistants, Junie gives you full control over the AI workflow. It features an advanced Plan Mode that writes structured requirements, design, and delivery stages before touching any code, and a Live Prompting system that lets you steer the agent mid-task without starting over. With persistent guidelines and Agent Skills, Junie learns your team's coding standards and remembers them across sessions.
