Frequently Asked Questions

How is sentence count calculated?

The tool detects sentences by ending punctuation: period, question mark, exclamation mark, and ellipsis. If text is not empty and contains no such marks, it may be counted as one sentence.

Are abbreviations such as "e.g." and "etc." handled?

Yes, when the abbreviation setting is enabled, abbreviations should not be treated as sentence endings. This helps avoid extra breaks in regular text.

What happens to numbers such as 3.14?

When the decimal number setting is enabled, decimal numbers are not treated as sentence endings, so 3.14 is not split into two phrases.

Can overly long sentences be found?

Yes. Set a sentence length limit in words and the tool shows how many sentences exceed it, along with the first long phrases found.

Is the service suitable for translation work?

Yes. The counter is convenient for comparing sentence count and translation structure with the original text.

How is this different from a word counter?

A word counter analyzes word count and uniqueness. A sentence counter focuses on text structure: sentence count, phrase length, and overly long sentences.
