“PLUG-in”

An add-on you install to give a program a new ability it did not ship with, without changing the program itself.

Think of it like…

A drill attachment. Same drill, new job, and you can swap it out any time.

Everyday example

Adding a grammar checker to your browser so it proofreads everything you type online.

Construction example

A takeoff plugin added to the estimating software so it can read measurements straight off a PDF plan.

Business example

A tax plugin added to the checkout system so the right rate is applied in every state.

Why this matters

Plugins let a business add exactly the capabilities it needs and skip the ones it doesn't pay for.

One-sentence summary

A plugin is a swappable add-on that gives existing software a new skill.
