What does an AI coding assistant like Copilot mainly do?

An AI coding assistant like Copilot mainly suggests and autocompletes code as a programmer types, predicting entire lines or functions based on patterns it learned from vast amounts of public code. It works much like an advanced autocomplete, offering suggestions that developers can accept, modify, or ignore, which can speed up routine coding tasks considerably while still requiring human review to catch mistakes or subtle bugs.

Physically repairing broken computer hardware is a mechanical task unrelated to a software tool that only works with lines of code on a screen. Removing the need for an internet connection is also false, since many AI coding assistants actually require an internet connection to access their underlying models.

Studies suggest developers using these tools can complete certain tasks noticeably faster, but the output still isn't perfect, meaning careful human oversight remains essential before AI-suggested code goes into a real product.
