Frequently Asked Questions
How does the sentence counter detect sentence boundaries?
It accurately splits sentences using ending punctuation marks (. ! ?) followed by whitespace or line breaks, while ignoring standard abbreviations and initials.
Why is flagging long sentences (>25 words) helpful?
Sentences longer than 25 words often fatigue readers and reduce comprehension. Shortening them improves readability scores like Flesch-Kincaid.
