JetBrains AI

Built-in AI for IntelliJ IDEA, PyCharm, WebStorm and other JetBrains IDEs

JetBrains AI is the subscription behind AI Assistant and Air in IDEs inside JetBrains IDEs. It covers code completion (JetBrains' own Mellum model by default), AI Chat, and coding agents: JetBrains' Junie plus Claude Agent, Codex and Gemini. Air in IDEs runs agents across several projects and shows their changes as IDE diffs. Usage is metered in AI credits (1 credit = $1, third-party models at API rates), and you can bring your own API keys or connect ACP agents such as Cursor without a JetBrains AI subscription.
