Paste or type and the totals update live, all in your browser, so even sensitive drafts stay private on your device.

FAQ
Is the sentence counter free?
Yes - it's 100% free, with no sign-up and no limits. Everything runs in your browser.
Is my text uploaded anywhere?
No. Sentences are counted locally in your browser; your text never leaves your device.
How does it decide where a sentence ends?
It uses your browser's built-in Unicode sentence segmentation (Intl.Segmenter), which handles period, question mark and exclamation across many scripts - including English, Chinese and Japanese - and ignores decimals and ellipses correctly.
Does it count an incomplete final sentence?
Yes. A trailing fragment without ending punctuation is counted as one sentence, since that's usually what the writer means.
What counts as a question or an exclamation?
Any sentence whose final non-space character is ?, ¿, ! or ¡. Everything else is counted as a statement.
Does it handle paragraphs and bullet lists?
Yes. Each paragraph or bulleted line counts as its own sentence even when the writer omits a final period, so unterminated lines aren't dropped from the total.
