Why it matters
- Deep JetBrains IDE integration uses existing code analysis context — suggestions reflect your project's type system, dependencies, and architecture rather than generic completions.
- AI commit message generation analyzes your diff and writes meaningful commit messages automatically — one of the most-used features for daily workflow.
- Inline prompt-to-code in the editor (no context switching to a chat window) keeps developers in flow state.
- Built on multiple LLM backends (GPT, Grazie) with JetBrains managing model selection — you get capabilities without needing to configure AI providers yourself.
Key capabilities
- Code completion: Multi-line AI completions in all JetBrains languages (Java, Kotlin, Python, JS/TS, Go, C#, PHP, Ruby, SQL).
- AI chat: In-editor chat with project context; ask questions about your code, request changes, get explanations.
- Inline generation: Write a comment describing intent → AI generates code inline with
/aiprompt. - Commit messages: One-click AI commit message generation from staged diff.
- Test generation: Generate unit tests for selected functions or classes.
- Documentation: Generate Javadoc, docstrings, or inline comments from selected code.
- Refactoring suggestions: AI-enhanced rename, extract method, and code smell detection.
- Code explanation: Explain selected code in plain English.
- Error explanation: Explain compiler errors, exceptions, and stack traces with suggested fixes.
Technical notes
- Supported IDEs: IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, DataGrip, PhpStorm, RubyMine, CLion
- AI models: GPT (via JetBrains), Grazie LLM, local model support (planned)
- Pricing: AI Pro $8.33/mo (annual); included in All Products Pack
- Trial: 7-day free trial
- Context: Project files, open files, git history, inspections
- Languages: All JetBrains IDE languages — 20+ major languages
Ideal for
- Developers who primarily work in JetBrains IDEs and want AI assistance without switching to VS Code or Cursor.
- Java, Kotlin, and .NET teams where JetBrains IDEs dominate and Copilot's VS Code-first approach is less relevant.
- Teams already paying for JetBrains All Products Pack — AI features are included without additional cost.
Not ideal for
- VS Code users — GitHub Copilot, Codeium, or Cursor are better fits.
- Teams wanting free unlimited AI completions — JetBrains AI Assistant has no free tier (unlike Codeium).
- Developers preferring open-source or self-hosted AI models — JetBrains AI is cloud-only currently.
