A fast, free sentence counter that analyzes your text in real-time. It counts sentences using punctuation detection (. ! ?), plus shows word count, character count, paragraph count, and estimated reading time. All processing happens in your browser — no data is sent to any server.
How does the sentence counter work?
The tool detects sentence endings by looking for period (.), exclamation mark (!), and question mark (?) followed by a space or newline. It handles abbreviations like "Dr.", "Mr.", "Mrs.", and "Ms." to avoid false positives.
Does it count paragraphs too?
Yes! The tool counts paragraphs by detecting blank lines (double newlines) or single newlines that create visual separation.
How is reading time calculated?
Reading time is estimated at an average adult reading speed of 200 words per minute. This is a rough estimate — actual speed varies by content complexity and reader proficiency.
Is my text private?
Absolutely. All counting happens inside your browser. Your text is never sent to or stored on any server.
