What is an AI coding tool?
An AI coding tool, also known as an AI code generator or AI coding assistant, is a software platform powered by artificial intelligence and machine learning that helps developers write code more efficiently.
It uses smart technology to guess what you’re trying to do and gives you suggestions as you work.
You can ask it to finish your code, find bugs, explain confusing stuff, or even build small projects for you.
