GitHub Copilot Review 2025: For Japanese Developers
GitHub Copilot is the most widely used AI coding tool among Japanese developers. After one year of daily use, here is the honest assessment of who it helps most.
What GitHub Copilot Does Well
- Boilerplate code: Tests, configuration files, standard implementations
- Autocomplete for known patterns: API calls, database queries, loops
- Explanations: Understanding unfamiliar code
- Documentation: Auto-generate docstrings and comments
Where Copilot Has Limitations
- Complex, project-specific logic (does not know your codebase like Cursor does)
- Multi-file changes (Cursor is significantly better)
- Architecture decisions and design patterns
Copilot vs Cursor Comparison
| Feature | GitHub Copilot ($10/month) | Cursor Pro ($20/month) |
|---|---|---|
| IDE Support | All (VS Code, JetBrains, Vim) | VS Code only |
| Codebase Context | Open files | Full codebase |
| Multi-file Editing | Limited | Excellent |
| Students | Free with GitHub Student Pack | No discount |
Recommendation
Choose Copilot: If you use JetBrains or Vim, or are a student (free!).
Choose Cursor: If you use VS Code on complex multi-file projects.
