JetBrains AI

JetBrains makes the most widely used professional IDEs outside of VS Code: IntelliJ for Java and Kotlin, PyCharm for Python, WebStorm for JavaScript and TypeScript, GoLand for Go, and others. JetBrains AI Assistant is their integrated AI layer, available as part of all JetBrains products. For teams whose entire workflow lives in JetBrains tools, it removes the need to add a separate AI coding tool on top.

The assistant provides inline code completions, a chat panel for questions and code generation, AI-assisted refactoring, and explanation of unfamiliar code. It connects to multiple underlying models and can use the full context of your open project, including your code structure, dependencies, and type information that JetBrains IDEs are particularly good at indexing.

JetBrains AI is not as agentically capable as Cursor or Claude Code for long-running autonomous tasks, but it's a solid choice for teams already committed to the JetBrains ecosystem and who want AI assistance that feels native rather than bolted on. It's also one of the few tools where the IDE's deep semantic understanding of code (knowing the types and structure of your codebase, not just the text) is fully leveraged by the AI layer.
