If you live in IntelliJ, PyCharm, or WebStorm, your AI choice is really between two: JetBrains' own AI, built into the IDE's soul, and GitHub Copilot, the everywhere-assistant that also runs in JetBrains IDEs.
Native depth versus broad ecosystem — here's the breakdown.
| JetBrains AI | GitHub Copilot | |
|---|---|---|
| Price | Free tier; Pro from $10/mo (+ IDE license) | $10/mo Pro (any IDE) |
| IDE integration | Deepest — refactoring, navigation, inspections | Extension-level, very good |
| Codebase context | Project-wide, semantic | Large, model-dependent |
| Agent features | Junie coding agent | Agent mode in chat |
| Outside JetBrains IDEs | Not available | VS Code, Neovim, Visual Studio, CLI |
| Best for | JetBrains lifers, JVM/Python | Multi-IDE developers |

Try GitHub Copilot →Inside a JetBrains IDE, JetBrains AI's integration is genuinely deeper — refactoring-aware, project-aware, hard to beat. But it costs extra on top of your IDE license and doesn't follow you elsewhere. Copilot is the portable pick: slightly shallower in IntelliJ, but one $10 subscription covers every editor you touch.
AI features need a compatible JetBrains IDE; the AI subscription itself is separate (Free/Pro/Ultimate tiers). Community editions have limited AI support.
JetBrains AI — IntelliJ's Java understanding plus AI is the strongest Java combo available.
Yes, they coexist fine. Some developers run Copilot for completions and JetBrains AI for chat/refactoring, though that's two subscriptions.
