Sentence Counter
Type or paste text and instantly see how many sentences it contains, alongside live word and character totals. A sentence counter helps writers gauge pacing and structure, meet assignment requirements that ask for a set number of sentences, or check that a summary is tight rather than rambling. This tool splits your text on full stops, question marks and exclamation points, treating runs like ellipses as a single break so the count stays sensible, and it ignores trailing punctuation that would otherwise inflate the total. The numbers update on every keystroke so you get feedback as you edit. Because it all runs in your browser, you can paste essays, drafts or client work safely; nothing is stored and nothing is sent anywhere.
