JetBrains AI Assistant

JetBrains AI Assistant is a plugin for JetBrains IDEs that brings AI-powered coding capabilities directly into your development environment. It provides inline code generation, smart completions, code explanations, and a chat interface powered by large language models. The plugin integrates seamlessly with the full suite of JetBrains IDEs, including IntelliJ IDEA, PyCharm, WebStorm, GoLand, and more. It is designed to help developers write, understand, and refactor code faster without leaving their IDE.

• AI Chat — Open the AI chat panel inside your IDE to ask questions about your code, get explanations, or request code snippets in natural language.
• Inline Code Generation — Trigger AI-powered code generation directly in the editor to produce functions, classes, or boilerplate based on a prompt or context.
• Code Completion — Receive multi-line AI completions as you type, going beyond traditional autocomplete to suggest entire code blocks.
• Code Explanation — Select any code snippet and ask the AI to explain it in plain language, making it easier to understand unfamiliar codebases.
• Commit Message Generation — Automatically generate meaningful Git commit messages based on the staged diff.
• Code Refactoring Suggestions — Ask the AI to suggest or apply refactoring improvements to selected code.
• Test Generation — Generate unit tests for existing functions or classes with a single action.
• Error Explanation — Get AI-powered explanations for compiler errors and exceptions directly in the IDE.
• Multi-IDE Support — Works across all major JetBrains IDEs including IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, CLion, and more.
• Context-Aware Responses — The assistant uses your project context, open files, and selected code to provide relevant, accurate suggestions.
