IntelliJ IDEA-powered capabilities

  • Deep code intelligence that saves tokens

    IntelliJ IDEA’s code intelligence for Java, Kotlin, and Spring helps your agent understand your project beyond individual files, so it produces better results with fewer tokens.

  • Advanced understanding of large codebases

    Your agent gets the context it needs to work with large projects and monorepos, with fast indexing and analysis that reveal how code, modules, and dependencies fit together.

  • Built-in support for Maven, Gradle, and Bazel

    Your build configuration isn’t just a panel – it feeds directly into IntelliJ IDEA’s intelligence, which recognizes the JDK and Java language level for every module independently. Build, run, and debug your code and tests right out of the box, with no additional configuration or extensions required.

  • Advanced debugger

    Get direct access to IntelliJ IDEA’s advanced debugger engine, so you can catch critical issues early or investigate how the code actually works – whether you’re coding manually or delegating to an agent.

Cursor’s agents get IntelliJ IDEA’s Java and Kotlin intelligence

“We’re glad to work with JetBrains to bring Java and Kotlin language intelligence to Cursor. With Java and Kotlin by IntelliJ IDEA, developers get IntelliJ IDEA’s code analysis, navigation, and refactoring while they work with Cursor’s agents.”

Agents 20–30% more efficient with IntelliJ IDEA’s code intelligence

“We created a benchmark with real programming tasks, which shows that with the JetBrains IDE’s code engine, agents are consistently more efficient – using fewer tokens and less time, with the exact gain depending on the model.”

常见问题及解答

It’s an extension that uses LSP to bring IntelliJ IDEA’s Java and Kotlin language intelligence to VS Code and VS Code-based editors such as Cursor.

The extension is intended for developers and teams who choose or need to work in VS Code-based environments. However, it does not replace IntelliJ IDEA as a standalone integrated development environment with agentic workflow support, an extended set of features and integrations, and support for other languages.

You can try it for free for 30 days. After that, an IntelliJ IDEA Ultimate subscription is required. The extension is also available as part of the All Products Pack subscription. Check our pricing page for more details.

Some functionality overlaps with the Java extensions from Red Hat and Oracle. We recommend disabling those while testing this extension to avoid conflicts.

See the IntelliJ IDEA Goes LSP announcement for the full story.
