A word counter is a device or software that tells you how many words you have written, and also the number of characters, sentences, and paragraphs in your document. Word counters can be used to keep track of the amount of words, sentences, and paragraphs in a document. These counters can also be used to determine the readability of a given text. They also provide an ability to calculate the readability score for any given piece of text. This is very important as it assures that the text is readable by a target audience, which leads to better engagement with content.
