Is my data uploaded or stored?

Which browsers does the Sentence Counter work in?

How does the free Sentence Counter detect sentences?

It splits on period, exclamation mark, and question mark followed by whitespace or end of string. Very short fragments (under 2 characters) are ignored to avoid false positives from abbreviations.

Does it handle ellipses (…) correctly?

An ellipsis is treated as a single sentence terminator, so "She waited… and waited…" counts as two sentences.
