What it is good at
| Strength | Detail |
|---|---|
| IDE-native | Understands JetBrains PSI — symbols, refactorings, inspections |
| Multi-language | Java, Kotlin, Python, Go, JS/TS in respective IDEs |
| Inline completion | Context-aware suggestions in JetBrains editors |
| Chat + actions | Explain, generate tests, convert code with IDE context |
| Enterprise | JetBrains Account licensing; data handling policies for teams |
| Copilot coexistence | Many teams run GitHub Copilot plugin alongside or instead |
Setup
- Update IDE to version with AI Assistant support (2023.3+ — verify for your IDE)
- Enable AI Assistant plugin (bundled in recent releases)
- Sign in with JetBrains Account; accept AI terms
- Configure model access per org policy (JetBrains-hosted vs BYOK where available)

Modes / core workflow
| Feature | Use when |
|---|---|
| AI Chat | Explain stack traces, explore APIs |
| Generate code | Boilerplate from natural language in editor |
| Explain commit | Summarize VCS changes |
| Fix with AI | Inspection/quick-fix integration |
Typical loop:
- Select code or open file with inspection warning
- Open AI Chat with context from editor
- Apply suggested patch through IDE diff preview
- Run IDE inspections and tests before commit
For JVM services, pair with Amazon Q or Copilot if org standardizes on those instead.
When to use it vs alternatives
| Choose JetBrains AI | Choose something else |
|---|---|
| Team already on IntelliJ/WebStorm | Cursor — if team standardizes on VS Code |
| Deep IDE refactorings matter | Aider — git-centric terminal only |
| Enterprise JetBrains license in place | Gemini Code Assist — GCP/Android-heavy shops |
| Kotlin/Java primary stack | Claude Code — headless CI automation |
See Choosing an AI Coding Tool — notes Copilot + Gemini cover JetBrains too.
Limitations
- Agentic multi-file autonomy less extensive than Cursor Agent or Claude Code in some workflows
- MCP/skills ecosystems less documented for JetBrains than VS Code
- Verify data retention and training opt-out for regulated industries
