How AI Coding Tools Actually Work
AI coding assistants are trained on billions of lines of open-source code. They understand programming patterns, common algorithms, and best practices — which lets them suggest relevant completions as you type, explain what code does, and generate entire functions from a description.
Cursor vs GitHub Copilot: which should you choose?
GitHub Copilot is the better choice if you want to stay in your existing editor (VS Code, JetBrains, Neovim). It integrates as a plugin with minimal disruption to your workflow. Cursor is the better choice if you want deeper AI integration — it understands your full codebase, supports longer context windows, and has a more powerful chat interface.
How to get the most from AI coding tools
- Write clear comments before functions — AI completes code based on your description
- Use chat mode to explain errors, not just to complete code
- Review all AI-generated code — it can introduce subtle bugs
- Use AI to write tests for existing code — it excels at this
- Ask AI to explain unfamiliar codebases — massive time saver when joining new projects
