AI pair programmer by GitHub/OpenAI — suggests code completions, writes functions, explains code, and generates tests in your IDE.
GitHub Copilot pioneered AI-assisted coding and remains the industry standard. Its inline completions predict what you're about to type and often get it right — especially for boilerplate, patterns, and common algorithms.
The chat feature lets you ask questions about code, generate functions from descriptions, and get explanations of unfamiliar code.
Every developer should try it. The free tier (2,000 completions/month) is enough to evaluate. Students get unlimited free access.
