How does the sentence counter work?
Paste text and the tool counts sentences by detecting period, exclamation mark, and question mark boundaries. Each sentence is shown individually with its word count.
What counts as a sentence?
Text ending with a period (.), exclamation mark (!), or question mark (?) is counted as a sentence.
Is my text sent anywhere?
No. All counting happens locally in your browser. Your text is never uploaded.
