# Typerbot :robot:

What is Typerbot?

Typerbot is a flexible library designed to mimic keyboard input into any DOM Element. Built on `Async/Await` , Typerbot provides an intuitive  API to let developers focus on unleashing their creativity instead of getting lost in the weeds. 

## Features

 - Typerbot can mimic any input from a keyboard, allowing users to move
   their cursor, delete characters, and enter new characters into a
   provided field element.
 - Use handy utility functions to expedite your development process and write code in a more declarative manner.
 - Create visually interesting effects by combining provided callbacks with CSS.
