How to count sentences
- Paste (or type) into the box — every statistic updates as you go.
- Read the Sentences tile; words and characters sit right beside it.
- Edit toward your target and watch the number move.
When sentence counts matter
Assignments that specify “8–10 sentences per paragraph”. Summaries capped at five sentences. Readability editing, where the fix for dense text is almost always more sentences, not fewer words — tracking the count while splitting long sentences shows progress instantly. Language learning exercises, abstract limits, and the classic teacher’s instruction to “vary your sentence length” (divide words by sentences as you edit and watch your average shift).
Why this count is trustworthy
Naive counters split on periods and get fooled by “Dr. Smith arrived at 5 p.m. from the U.S.” — one sentence, three false endings. This counter uses the Unicode segmentation rules built into your browser, which know abbreviation patterns and terminal punctuation across languages. The same engine powers the word counter — this page simply puts sentences front and center. Cleaning up pasted text first? Remove line breaks un-wraps PDF copy so paragraph and sentence detection see the text as it was written.
Private by design
Counting is JavaScript running on your device — essays, manuscripts, and confidential drafts never leave your browser, and there’s no length limit because there’s no upload.
