How to Use This Text Tool

  1. Paste or type your text into the input field.

What Is a Sentence Counter?

Counting sentences sounds simple but is tricky: a naive split on periods miscounts every passage that contains "Mr.", "Dr.", "U.S.", "e.g.", "i.e.", "etc." or a decimal number. A useful counter filters those abbreviations and only splits when a period, exclamation mark or question mark is followed by whitespace and a capital letter.

Alongside the sentence count, the tool reports the average words per sentence — a quick readability indicator. Short averages (10–15 words) read fast and feel punchy; long averages (25+) feel dense and academic. Editors use it to spot paragraphs that need tighter rhythm.

Nothing leaves your browser, so drafts stay private.

Frequently Asked Questions

How are sentences detected?
Sentences are split on terminal punctuation (.!?) followed by whitespace and a capital letter. Common abbreviations like Mr., Dr., U.S., e.g., and i.e. are filtered out to avoid false splits.
Why count sentences?
Sentence count helps with readability metrics (average words per sentence), editing, and ensuring balanced structure in essays, articles, and copywriting.
Does it work with bullet points?
Bullet points without ending punctuation may not be counted as full sentences. The counter focuses on properly punctuated sentences that end in . ! or ?
