Frequently Asked Questions
How does it split sentences?

It uses common sentence-ending punctuation such as periods, exclamation marks, and question marks as a practical browser-side estimate.

Can it handle multiple paragraphs?

Yes. It also estimates paragraph count based on blank-line paragraph breaks.

Is the count always perfect?

No automated sentence parser is perfect. Abbreviations and unusual punctuation can affect the estimate, but it works well for most normal prose.

Is the text uploaded?

No. The analysis stays in your browser.
