Auto clickers are a type of software or macro that can be used to automate clicking. They can be triggered to generate input that was recorded earlier or generated from various current settings.

Auto clickers can be as simple as a program that simulates mouse clicking. This type of auto-clicker is fairly generic and will often work alongside any other computer program running at the time and acting as though a physical mouse button is pressed.

More complex auto clickers can similarly be as general, but often are custom-made for use with one particular program and involve memory reading. Such auto clickers may allow the user to automate most or all mouse functions, as well as simulate a full set of keyboard inputs. Custom-made auto clickers may have a narrower scope than a generic auto clicker.
