The tool analyzes Unicode text in the browser and keeps the source visible while producing a separate result. Selected whitespace, ordering, capitalization, or replacement rules are applied deterministically.

Counts and transformations never require an upload. Review generated text before publishing because language-specific capitalization, word boundaries, and URL conventions can vary.
