Frequently Asked Questions

FAQs about Sentence Counter

How does it detect sentence boundaries?

The tool splits text on . ! or ? when followed by a space or end of string. Abbreviations like "Dr." or "U.S.A." may cause slight over-counting.

Does it count empty or whitespace-only sentences?

No. Empty segments after splitting are ignored.

Is this good for readability analysis?

Yes. Average sentence length (words ÷ sentences) is a key component of readability scores like Flesch–Kincaid.

Does it handle ellipsis (…)?

A single ellipsis character (…) is not treated as a sentence boundary. Three dots (...) may trigger a count depending on spacing.

Does the count update in real time?

Yes. The count updates instantly as you type or paste.
