About this category

These tools handle the text chores that come up in writing, editing, and data cleanup. Statistics update as you type, conversions keep your original line order unless you ask for sorting, and comparisons show exactly what changed without uploading your draft anywhere.

Because everything runs in the browser, you can paste unpublished copy, client notes, or log excerpts without handing them to a third party.

Word, character, sentence, and paragraph counts with clear caveats for Chinese, Japanese, and Korean text.
Duplicate removal and line sorting with explicit comparison options.
Side-by-side text comparison that labels added and removed content, not just colours it.
