What is Sentence Counter?
The Sentence Counter identifies and counts sentences in text. It recognizes sentence boundaries at periods, question marks, and exclamation points while handling abbreviations like 'Dr.' and 'etc.' so they do not inflate the count. The tool also reports word count, character count, paragraph count, average words per sentence, and reading time. All processing happens in the browser.
How does Sentence Counter work?
This tool scans your text for punctuation marks that typically end sentences. It uses a list of common abbreviations to avoid false positives at periods that follow 'Mr.', 'Dr.', 'vs.', and similar. It counts each sentence-ending punctuation mark as one sentence, and treats the final sentence (even without ending punctuation) as a sentence if it contains words.

Frequently Asked Questions
How does it handle abbreviations?
The tool checks periods against a list of common abbreviations. If a period follows 'Dr.', 'Mr.', 'vs.', 'etc.', or similar, it is not counted as a sentence boundary.
Does it count questions and exclamations?
Yes. Question marks and exclamation points are recognized as sentence endings alongside periods.
What if a sentence has no ending punctuation?
The final sentence in the text is counted even if it lacks ending punctuation, as long as it contains words.
Is my text uploaded to a server?
No. All processing happens in your browser using JavaScript. The text never leaves your device.
Can I count sentences in a large document?
Yes. The tool handles documents of any length. Very large texts may take a moment on older devices.
