How to use this sentence counter
Paste prose. Sentences are split on period, question mark, and exclamation point. A trailing fragment without end punctuation still counts as one sentence.
Use it with the word counter to watch average sentence length while you edit.
Example
Hello. Is this two sentences? Yes.

Frequently asked questions
How do you detect a sentence?
A run of text ending in . ! or ? counts as a sentence. Abbreviations like U.S. can over-count.
Does it work for dialogue?
Quotes and ellipses are not a full linguistic parser. Spot-check literary text.
