Good to know

Text stays in this tab. Maximum 100,000 characters. Word and sentence boundaries are estimates; language and punctuation can change counts.

Your privacy

Processing happens on this device for this tool. We do not upload your input, put it in share links or save it to your favourites. Closing this tab discards the working input; downloaded results remain wherever you save them.

When this tool is useful

Use Sentence Counter when you need a quick, local result and want the rule or limitation visible alongside it.

How to use it

  1. Enter the input using the labels shown.
  2. Run the operation and review the result.
  3. Download or copy the result only after checking it.

Checks before you rely on the result

  • Text stays in this tab. Maximum 100,000 characters. Word and sentence boundaries are estimates; language and punctuation can change counts.
  • Keep the original input when the operation creates a new copy.
  • Use the related tools below when the next step needs a different format.

This page is maintained with the tool implementation and its deterministic tests. If the result looks wrong, report the issue with a non-sensitive example.
