What is a Sentence Counter
A sentence counter counts sentences in your text. It takes the tedious task of tracking sentence count in essays, articles, scripts and more and turns it into a quick, simple one-click process.
A sentence calculator scans your text for sentence-ending punctuation like periods, question marks, and exclamation points, while checking for common abbreviations such as "Mr.", "Dr.", or "U.S." so a period after them doesn't get mistaken for a sentence break.
The result is a sentence count that matches how a person would actually read your text, not just a raw count of periods.
