Key Features of JetBrains AI Assistant in IntelliJ IDEA:

AI Chat: A context-aware chat interface directly within the IDE.² You can ask programming questions, iterate on tasks, search for files and usages, get insights, and even get answers about IDE features.³ It supports various top-tier LLMs like Google Gemini, OpenAI, and Anthropic, and also allows connecting local AI models (e.g., via Ollama or LM Studio).⁴
Code Generation:
- Real-time Code Completion: AI-powered suggestions for single lines, entire functions, and even blocks of code.⁵ JetBrains uses its own coding-optimized LLM called Mellum for unlimited code completion.⁶
- Generate Code in Editor: Directly generate code from comments or natural language prompts.⁷
- Convert Files to Another Language: Translate code from one programming language to another.⁸
- Generate Tests: Automatically create unit tests for your code.⁹
Code Understanding and Refactoring:
- Explain Code: Get AI-powered explanations for code fragments.¹⁰
- Suggest Refactorings: AI Assistant can propose and explain potential refactorings for your code, taking project constraints into account.¹¹
- Rename Refactorings: Context-aware name suggestions for declarations.¹²
Documentation and Commit Messages:
- Generate Documentation: AI can write documentation for declarations directly in the editor.
- Generate Commit Messages: Automatically create high-quality commit messages based on your code changes.
- Explain Commits: Understand existing commits with AI assistance.¹³
VCS Integration: Features like generating titles and descriptions for pull/merge requests and resolving Git conflicts with AI assistance.¹⁴
Multi-file Edits (Beta): Apply changes across multiple files directly from the AI chat.¹⁵
Web Search from Chat: Use a /web command within the chat to search the internet for technical documentation, troubleshooting tips, etc.¹⁶
Context Management: You have full control over the AI's context in the chat, allowing you to add or remove files, symbols, and commits to tailor responses.¹⁷ You can also exclude specific files from AI context using an .aiignore file.¹⁸
Local and Cloud AI Options: You can choose to use cloud-based AI models or integrate your own locally hosted models for offline work and enhanced security.¹⁹
Junie (Coding Agent): This is a more advanced AI-powered agent designed to automate and supervise complex development workflows. Junie can scan your project, generate development plans, and execute tasks across multiple files. It's meant to augment, not replace, developers, helping them accelerate iteration and explore new ideas.²⁰

Pricing and Availability:

While some basic AI features like unlimited code completion with Mellum and local AI usage are available in a free tier, many of the more advanced features of the AI Assistant require a paid JetBrains AI subscription (AI Pro or AI Ultimate).

In essence, JetBrains is deeply integrating AI into the core workflows of IntelliJ IDEA to enhance developer productivity, reduce routine tasks, and provide intelligent assistance throughout the coding process.²¹
