A sentence counter is a small tool that tells you how many complete sentences you have written. It looks at your text, finds sentence-ending punctuation like periods, question marks and exclamation points, and then counts the resulting segments as sentences.
This is useful for writers, students, editors, bloggers and anyone who cares about readability and structure. Instead of guessing, a sentence counter gives you a clear number so that you can adjust your text with confidence.
When you know your sentence count, you can quickly see if your writing is too choppy or too heavy, and rewrite parts that need more balance.
The tool offers two modes of sentence detection:
., ? and !.In both modes, the sentence counter removes empty fragments and counts only segments that contain real text. This keeps the result realistic even when you paste rough drafts or notes with extra spacing.
All processing happens locally in your browser, so the tool feels instant and your content stays private.
Yes. This sentence counter is completely free to use and does not require any registration or login.
No. All calculations are performed directly in your browser. Your text is not sent to a server or stored anywhere.
Different sentence counter tools use different rules for abbreviations, dialogue and complex punctuation. Small differences between tools are normal.
If you are working with clean, well-punctuated text, strict mode is usually the best choice. If your text contains many bullet points, fragments or rough notes, relaxed mode can give you a more generous estimate of the number of sentences.
