JetBrains AI
Native AI assistant across all JetBrains IDEs — completions, chat, refactoring, and the Junie agent.
About
JetBrains AI is the native AI assistant built into the full JetBrains IDE lineup — IntelliJ IDEA, PyCharm, WebStorm, Rider, and the rest. It offers context-aware code completion, in-IDE AI chat, refactoring, test generation, and documentation, all grounded in the IDE's deep code analysis rather than just open files.
It supports multiple models including OpenAI, Google Gemini, Anthropic Claude, and JetBrains' own Mellum code model, with both cloud and local LLM options. Junie, the autonomous coding agent, handles multi-step tasks under developer supervision. Pricing runs on AI credits: AI Free ($0, limited credits), AI Pro ($100/year, 10 credits/month), AI Ultimate ($300/year, 35 credits/month), and Enterprise with on-premise options.
Worth knowing: it only works inside JetBrains IDEs — there is no standalone usage. Cloud features consume monthly credits, which can feel restrictive for heavy users, and paid tiers require an active IDE license on top. But for teams already living in JetBrains IDEs, the depth of integration beats bolt-on assistants.
