Paste your text and instantly see the sentence count, word count, character count, and average sentence length.
A sentence counter scans your text and counts how many sentences it contains by detecting sentence-ending punctuation such as periods, question marks, and exclamation points. Unlike a simple word count, it looks at how your ideas are broken into complete thoughts, which is useful for essays, articles, and any writing with a required sentence count.
Most word processors, including Microsoft Word and Google Docs, show you a word count but leave out sentence count entirely. This tool fills that gap and adds a few extra details: paragraph count, average sentence length, and your longest sentence, all updated live as you type.
The tool splits your text at periods, question marks, and exclamation points, then filters out common abbreviations like Mr., Dr., and e.g. so they are not mistaken for the end of a sentence. What remains is counted as one sentence per detected ending.
Average sentence length is calculated by dividing the total word count by the number of sentences. Shorter average sentence length usually means easier reading, which is one of the signals used in readability formulas like Flesch-Kincaid.
For students, many assignments and essays specify a minimum or maximum number of sentences or paragraphs, and this tool checks both instantly. For writers and marketers, shorter and more balanced sentences tend to improve readability and keep readers on the page longer, which can be a positive signal for SEO.
It scans your text for sentence-ending punctuation such as periods, question marks and exclamation points, while ignoring common abbreviations like Mr., Dr. and e.g. so they are not miscounted as separate sentences.

Word and Google Docs both show a word count, but neither one displays a sentence count. You would have to count manually or use a separate tool like this one.
Shorter, clearer sentences generally improve readability scores such as Flesch-Kincaid, which correlates with better on-page engagement and can support SEO performance.
