GitHub Copilot

GitHub's AI coding tools for editor assistance, agents, code review, and issue-to-pull-request workflows.

Use an assistant in your coding environment, inspect proposed changes, and run the project's checks before merging.

Access and pricing: Free provides limited chat and agent usage. Paid plans include larger allowances; agentic features consume GitHub AI Credits and can involve additional usage charges.

Try this task: Add a boundary test to existing code Give the assistant a function that sums paid rows and request a test for an empty list and an unpaid row.

Check the result: Expected totals: [] gives 0; paid 10 plus unpaid 99 gives 10. Confirm the test runs against the real function.

Choose carefully: A suggested test can mirror a mistake; define the expected behavior independently.

Evidence: This is an editorial exercise based on the documented product scope, not a recorded hands-on product benchmark. Use permitted or fictional inputs and record your own observed result.

What it does well

GitHub's plans page shows a Free plan alongside paid tiers, so you can try Copilot before paying. The product covers editor assistance, agents, code review and issue-to-pull-request workflows, per the existing listing.

Who gets the most from it

Developers working in GitHub repositories, where suggestions can reflect nearby code and tests, are the obvious audience. Business covers the IDE, CLI and GitHub Mobile with license and policy management, and Enterprise adds GitHub.com chat and codebase indexing.

Limits to check before you commit

The plans page lists Free at $0 with 2,000 inline suggestions per month and 50 chat requests (including Copilot Edits). Pro is $10 per month, Pro+ is $39 and Max is $100, each with unlimited inline suggestions and monthly AI credits ($10, $39 and $100 base, with extra flex allotments listed). Business and Enterprise prices are via sales. Agentic features consume AI credits and can bring additional charges. Treat suggestions as drafts and run your tests.
