Overview
For developers using IntelliJ IDEA, PyCharm, WebStorm, GoLand, or other JetBrains IDEs, this is a practical daily question: use JetBrains AI Assistant or install the GitHub Copilot plugin? Both cost ~$10/month. Both work in your IDE. The difference is integration depth vs. ecosystem breadth.
How each tool works
JetBrains AI Assistant is built natively into all JetBrains IDEs. It has access to the IDE's full project model — indexed symbols, type information, dependency relationships, and refactoring capabilities. AI-powered refactoring, test generation, and commit message generation are woven into IDE actions, not bolted on.
GitHub Copilot in JetBrains works as a plugin. Completions appear inline and the chat panel is accessible, but it doesn't have the same depth of access to the IDE's internal project model that a native integration has. Copilot's GitHub integration (PR review, Copilot Workspace) adds value beyond the editor.
Feature comparison
| JetBrains AI Assistant | GitHub Copilot | |
|---|---|---|
| IDE integration depth | Native | Plugin |
| Refactoring with AI | Yes (IDE-native) | Limited |
| Test generation | Yes (IDE-native) | Yes |
| Commit message AI | Yes | No |
| PR review | No | Yes (GitHub) |
| GitHub integration | None | Deep |
| Editor support | JetBrains only | VS Code, JetBrains, Vim, etc. |
| Pricing | ~$10/month | $10/month Pro |
The integration depth argument
JetBrains AI Assistant's native integration shows in actions like: rename a method and the AI understands all callers; generate a test and it knows your exact test framework; suggest a commit message understanding your branch's Jira ticket reference. A plugin can't replicate this IDE-awareness.
Copilot's counterargument: stronger models for general code completion and GitHub's ecosystem integration is significant for teams using GitHub for code review.
Verdict
GitHub users: Copilot is the obvious choice — the GitHub ecosystem integration is significant. Non-GitHub JetBrains users (GitLab, Bitbucket, self-hosted): AI Assistant's native integration provides better daily value and you avoid paying for GitHub features you don't use.
