Frequently asked questions
How does the tool decide what counts as a sentence?
Sentences are identified by their terminating punctuation: periods (.), exclamation marks (!), and question marks (?). Each run of these end-marks closes one sentence, which is how most plain-text sentence counting works.
Will abbreviations like 'Dr.' or 'U.S.A.' throw off the count?
They can. Because the tool keys off periods, abbreviations, initials, and decimal numbers may occasionally be read as sentence boundaries. For most prose the count is highly accurate, but very abbreviation-heavy text may be slightly over-counted.
What happens if my text has no ending punctuation?
If there are no periods, exclamation marks, or question marks, the tool reports that no distinct sentences were found and suggests checking your punctuation. Adding proper end marks lets it count correctly.
Why count sentences at all?
Sentence counts help you gauge readability and pacing, keep paragraphs balanced, meet assignment or content-length requirements, and calculate average words per sentence for clearer writing.
Is my text kept private?
Yes. All counting happens in your browser and no text is uploaded to a server, so you can analyze sensitive or unpublished content for free without privacy concerns.
