JetBrains Introduces AI Assistant Across All IDEs and .NET Tools

JetBrains announced that a new AI Assistant will be integrated into every JetBrains IDE (such as IntelliJ IDEA, CLion, PyCharm) and .NET tools (including ReSharper, Rider, dotPeek). The feature is part of the JetBrains AI Service, which connects users to various large language models and supports OpenAI and JetBrains‑hosted models.

AI Chat

Developers can open the AI Assistant tool window to converse with the model, ask questions, or get context‑aware answers based on the current project; accepted suggestions can be inserted directly into the code.

Code Understanding

The assistant also provides code‑understanding capabilities. By selecting code and invoking the AI Actions menu, developers can request code‑segment explanations, refactoring suggestions, or potential issue detection.

Documentation Generation

AI can automatically generate documentation or comments for Java, Kotlin, and Python code. For example, typing /** in a Java or Kotlin file triggers the generation of a Javadoc‑style comment.

Naming Suggestions

When renaming variables, functions, or declarations, the assistant analyses the surrounding context and proposes appropriate names for Java, Kotlin, or Python code.

Commit Message Generation

The new Generate Commit Message with AI Assistant button in the Commit dialog creates a commit message based on the diff of code changes, streamlining the version‑control workflow.

Overall, the AI Assistant brings generative‑AI capabilities directly into JetBrains products, improving efficiency in coding, documentation, and version control, with plans to expand model support and eventually offer on‑premise deployment.
