What is Sentence Counter?
The sentence counter reports how many sentences, words, characters and paragraphs a piece of text contains. It updates live and helps writers check length limits and readability at a glance.
How It Works
Sentences are detected by terminal punctuation such as periods, question marks and exclamation marks, including common CJK punctuation. Words are split on Unicode whitespace, and paragraphs are split on blank lines.
Common Use Cases
- Checking sentence length for readability
- Meeting academic or editorial limits
- Reviewing translated copy structure
- Tracking paragraph counts in drafts

FAQ
How are sentences detected?
The tool counts terminal punctuation marks followed by whitespace or the end of the text. Abbreviations like Dr. can therefore add an extra count.
