What is JetBrains AI Assistant?

JetBrains AI Assistant brings AI chat, completion, and agentic help into IntelliJ IDEA, PyCharm, WebStorm, and the rest of the JetBrains family, where it can lean on each IDE's deep understanding of your project — indexes, refactorings, run configurations, and debugger state. Google's and OpenAI's models are available alongside JetBrains' own Mellum completion model.

The Junie agent can carry out multi-step coding tasks inside the IDE, and AI features extend to commit messages, documentation, and test generation. A limited free quota is included with JetBrains IDEs, with paid AI tiers unlocking far more usage; developers who do not already use JetBrains tools gain little, since the assistant is not sold standalone.
