Sentence Counter
Count sentences in your text.
Sentence count matters for readability analysis, academic writing guidelines, and copywriting quality checks. Utilitoo's Sentence Counter detects sentence boundaries using standard terminators and displays sentence, word, and character counts live as you type.
Students verify essay requirements, editors assess paragraph pacing, and NLP practitioners need quick sentence statistics without installing desktop tools. Paste any text block and get instant counts.
The tool splits on period, exclamation, and question mark terminators. Abbreviations like Dr. or e.g. may occasionally count as sentence breaks - review edge cases for formal documents. Pair with Word Counter for full statistics or Reading Time Calculator for time estimates.
All analysis runs locally in your browser on Utilitoo. Your text is never uploaded. Free for writers, students, and editors.
Sentence Counter fits early-stage writing and editing workflows: draft in your editor, paste here for counts or transforms, then return to your document. Because processing is local, you can use client-confidential or embargoed copy without sending it to a cloud service. When working with very large texts, split into sections if the browser becomes sluggish.
Common use cases
- Count sentences in your text - a common daily workflow on Utilitoo.
- Preparing sentence counter output for blog posts, documentation, or social content.
- Batch-processing copy for editors, marketers, or technical writers on deadline.
- Checking sentence counter metrics when a word processor's built-in counter is unavailable.
- Cross-checking Sentence Counter output against a colleague's result during pair debugging or code review.
Tips & common mistakes
Sentence Counter processes your text locally in the browser - nothing is sent to Utilitoo's servers. For best results, paste plain text rather than rich-formatted content when the tool expects raw input. Keep a copy of the original before applying destructive transforms like sorting or deduplication, so you can revert if the output is not what you expected. For long documents, Sentence Counter may take a second to process in the browser. Combine with Remove Extra Spaces or Remove Duplicate Lines when cleaning text exported from PDFs or web pages. If you need both word and character counts, run Word Counter and Character Counter on the same paste.
