Frequently asked questions

How are sentences detected?

The tool splits on common sentence-ending punctuation such as periods, question marks, and exclamation points, including ellipses. It counts sentences — it does not rewrite grammar or check spelling.

What counts as one sentence?

Text ending with sentence-ending punctuation is treated as a sentence. Incomplete fragments without an ending mark may not count until you finish them.

Does it work with abbreviations like “Dr.”?

Abbreviations that use periods can split early. For precise academic counts, scan those spots after the automatic pass.

Should I use Word Counter or Sentence Counter?

Use Sentence Counter when you care about sentence totals and length. Use Word Counter for word totals and reading time, or Character Counter for character limits.

Is sentence counting uploaded?

No. Everything runs locally in your browser.
