Frequently Asked Questions
How are words counted?
Words are counted by splitting text on whitespace. Consecutive spaces count as one separator. Leading/trailing spaces and empty lines are ignored in the word count.
How is reading time calculated?
Reading time is based on the average adult reading speed of 200 words per minute. A 1,000-word article takes approximately 5 minutes to read.
What counts as a sentence?
Sentences are detected by periods (.), exclamation marks (!), and question marks (?). A block of text without terminal punctuation is counted as one sentence.
Does the tool show characters with and without spaces?
Yes. The tool shows two separate counts: total characters (including spaces, punctuation and line breaks) and characters without spaces.
Is my text sent to a server?
No. All counting is done entirely in your browser using JavaScript. Your text never leaves your device and is never stored anywhere.
