Sentence Counter FAQ
What is a sentence counter?
A sentence counter is a writing tool that counts sentence-ending patterns in pasted text so you can review sentence totals, average sentence length, and pacing before publishing.
How does this tool count sentences?
It uses punctuation rules, whitespace cleanup, and common abbreviation handling to estimate sentence boundaries. The result is useful for editing, but unusual lists or fragments can still need human review.
What is a good average sentence length?
For general web and classroom writing, many drafts read clearly around 12 to 20 words per sentence. Technical or legal writing may run longer, but dense lines often benefit from splitting.
Can I use this for essays or articles?
Yes. Paste an essay, article, speech, email, or report to see sentence count, word count, paragraph count, average sentence length, and the longest sentence.
Is my text uploaded to a server?
No. The sentence counter runs in your browser. Your pasted text is analyzed locally and is not submitted to Lie Library.
