What Are AI Coding Tools?

Plain language: AI assistants that help you write code, fix bugs, and design architecture.

How you used to write code:

Hit a problem → Baidu/Google → Read docs → Try → Maybe solve it
Write a new feature → Read tutorials → Code along → Fix bugs → Done

How you write code now:

Hit a problem → Ask AI → Direct answer
Write a new feature → Describe the requirement → AI helps you write → Tweak → Use

Efficiency improvement: 3-5x.
