JetBrains AI Assistant

What is JetBrains AI Assistant?

JetBrains AI Assistant brings AI features into JetBrains IDEs such as IntelliJ IDEA, PyCharm, WebStorm and others. It offers code completion, chat, explanations, refactoring and test generation, and works alongside Junie, JetBrains' coding agent for multi-step tasks.

JetBrains IDEs have deep understanding of code structure, and the AI features build on that context. You can ask questions about code, generate documentation, write tests, explain errors and get suggestions while typing.

Junie is JetBrains' agent for larger tasks: it plans and executes changes across a project, runs tests and reports back, with the developer reviewing the results.

AI features support multiple models, including options to use local models, and enterprise controls for organizations.
