Very long sentences can hurt readability scores and make text harder to skim. Counting sentences alongside words helps you estimate average sentence length — a common signal used by readability tools like Flesch-Kincaid.
Paste text into Sentence Counter and read the live result. Nothing is sent to a server for typical use — adjust the input until the output looks right, then copy it.
Start with a short sample to confirm the reading. Large pastes are fine once you trust the output. Use Reset if you want a clean slate.
Whenever possible, Sentence Counter processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.
It splits text on periods, question marks and exclamation points followed by a space or the end of the text, which covers the vast majority of real-world writing.
Very short texts with many abbreviations can occasionally be over-counted; for precise legal or academic counts, always double-check manually.
