Counting runs in your browser. Nothing you paste is sent to our servers.

How it works

Paste or type text into the input. The live sentence count updates as you type (light debounce).

Counting rules (simple heuristic, not NLP): `.`, `?`, and `!` end a sentence when followed by whitespace or the end of the text. Repeated terminators such as `!!!` count as one boundary. Empty or whitespace-only input shows 0—no error. Text with no terminator still counts as one sentence when it has content.

Limits: abbreviations like `Mr.` or `e.g.` can inflate the count because periods inside them look like sentence ends. This tool does not use language detection or abbreviation dictionaries.

Use Example to load a sample, or Clear to reset. Counting runs entirely in your browser.

Examples

  • Hello. How are you? Fine! → 3 sentences
  • hello world → 1 sentence (no terminator)
  • Mr. Smith went home. → 2 sentences (abbreviation caveat)
  • (empty or spaces only) → 0 sentences

FAQ

Is my text uploaded to a server?

No. Sentence counting runs entirely in your browser. Pasted content is not sent to Nova Engine.

Do I need an account?

No. All published tools work for guests without login.

How accurate is the sentence count?

It uses a simple .?! heuristic, not full NLP. Abbreviations (Mr., e.g.) and unusual punctuation can produce higher or lower counts than a human editor would.

What about word or paragraph counts?

Those are separate tools in the Text category (Word Counter, Paragraph Counter) as they ship. This page focuses on sentence count.
