About TextKit Pro
TextKit Pro bundles thirteen everyday text utilities into a single page. For writing there is a word counter with keyword density, text statistics with a Flesch readability score, and a Lorem Ipsum generator for mockups. For editing there is find and replace with full regular-expression support, sort and dedupe lines, and a diff checker that highlights line-by-line changes. For developers there is a case converter covering nine formats, Markdown ↔ HTML and CSV ↔ JSON conversion in both directions, and a slugify tool that turns a title into a URL-safe slug. For tidying up whatever you just pasted there is remove line breaks, which joins wrapped lines or unwraps a paragraph copied out of a PDF, and reverse text, which flips text by character, word or line. The text cleaner runs seven of those cleanup passes over one paste at once — extra spaces, punctuation, special characters, numbers, emoji, HTML tags and accents — and each pass also has a page of its own.
Everything runs client-side in your browser — nothing you type or paste is ever uploaded to a server, so there's no wait and nothing to worry about privacy-wise.
