How are words and characters counted?

The tool uses Intl.Segmenter with the English locale when available. Characters are grapheme clusters, so an emoji sequence or a letter with combining marks counts as one character. Older browsers use a documented approximate regex fallback.

How is keyword density calculated?

Occurrences are divided by all possible phrases of the same length within sentences and lines. Stop-word filtering hides any phrase containing a common English stop word without joining words around it.

Is my text uploaded or saved?

No. Counting happens in your browser, and pasted text or loaded file contents are never persisted. Saved preferences and share links contain counting options only. Inputs are limited to 500,000 UTF-16 code units.

Text to count

0 characters

Counts use English-locale Unicode segmentation. Characters are grapheme clusters, so emoji and combining marks stay together. All whitespace is excluded from the second character count; CRLF is one cluster. Blank lines separate paragraphs; a trailing newline adds a line. Maximum input: 500,000 UTF-16 code units.

The share link contains only counting options. Your text is never saved or included.
