GitHub Copilot

GitHub Copilot assists software development through code suggestions, chat and agent features. Its main appeal is proximity to a developer’s existing workflow: help can sit alongside the editor and the repository rather than in a separate writing tool.

What you can do

• Code suggestions and chat in supported development environments.
• Assistance with explaining code and developing changes.
• Individual and organization plans with different usage and administrative controls.

A useful starting workflow

When working on an unfamiliar function, ask for an explanation of its inputs, outputs and failure paths before requesting a rewrite. Provide a concrete example of the intended behavior. Review the generated implementation for edge cases, then use the repository’s existing tests and build process to assess the change.

What to check

Suggestions can be plausible without meeting the project’s security, licensing or architectural requirements. Check dependencies and copied patterns, especially when a response introduces a library. A successful completion should leave you able to explain the code you are about to ship.

Pricing and access

Copilot offers a free plan alongside paid individual and organization subscriptions. Feature access and request limits differ by plan.
