Free Online Sentence Counter

A sentence is a grammatical unit that typically ends with a period (.), question mark (?), or exclamation point (!). Our tool uses advanced algorithms to accurately identify sentence boundaries while accounting for abbreviations, decimal numbers, and other edge cases that could create false positives.

Our sentence counter is smart enough to recognize common abbreviations (Dr., Mr., Mrs., Ms., Prof., i.e., e.g., etc.) and won't count them as sentence endings. The algorithm also handles decimal numbers (like 3.14) and ellipses (...) correctly, ensuring accurate sentence counts.

You can upload documents in TXT, DOCX (Microsoft Word), and PDF formats. Simply click the 'Upload Document' button and select your file. The tool will automatically extract and analyze the text content from your document.

Our tool uses sophisticated pattern recognition to achieve over 95% accuracy in most cases. It handles complex scenarios like acronyms, abbreviations, decimal numbers, and multiple punctuation marks. However, extremely unconventional writing styles or heavily formatted text may occasionally produce slight variations.

Sentence counting is valuable for students checking assignment requirements, writers analyzing readability, editors ensuring consistent sentence length, content creators optimizing for SEO, legal professionals reviewing document complexity, academics analyzing writing styles, and anyone needing quick text statistics.
