A word counter is a handy tool for writers of all levels, not just professional copywriters. It is an invaluable way to keep track of the number of words in any given document, but it does more than just that. Word counters can also help anyone edit their work.
There are many reasons to use a word counter. Many students and authors will use a word counter to make sure they stay within the restrictions of their assigned or desired word count. Some people like to know how many words they've used in order to save time and energy when writing. Others might use a word counter as an editing tool, counting how many times they've used a certain word as a way to avoid repetition.
Many people find it helpful to count the number of words in their writing. For example, if one is writing a 500-word essay about an event they attended, they might want to count the essay or text to ensure they are around the 500-word mark.
