Our verdict
GitHub Copilot is the AI tool with the clearest, most measurable productivity impact. GitHub's own research found that developers complete tasks 55% faster with Copilot enabled. That number holds up in independent evaluations for routine coding tasks — boilerplate, utility functions, test cases, documentation.
Copilot Chat, added in 2023, goes beyond autocomplete: you can ask it to explain code, fix bugs, generate tests for selected functions, or refactor for readability. It understands your entire workspace context, making suggestions that actually match your project's patterns and naming conventions.
The integration is seamless for developers already using GitHub. VS Code gets the best experience, but JetBrains, Neovim, and the CLI are all well supported.
At $10/month for individuals, it pays for itself within days for any professional developer. The Business tier at $19/month adds privacy controls, policy management, and audit logs.
Limitations: it occasionally generates confident but subtly wrong code, particularly in edge cases. Security researchers have demonstrated that Copilot can suggest vulnerable code, so code review remains essential.
