Clean Paste AI

Clean Paste AI exists for one moment in a workflow: the second between copying text and pasting it somewhere that matters. Anything copied out of a chat window, a PDF, a Google Doc or a web page carries formatting you cannot see — zero-width characters, non-breaking spaces, smart quotes, em dashes swapped in for hyphens, soft line breaks in the middle of sentences and, increasingly, the hidden Unicode markers that some models and watermarking schemes leave behind. None of it shows in the editor. All of it can cause visible problems later: a search that fails to match, a CSV import that splits on the wrong character, a code block that throws a syntax error because the quotes are typographic, or a CMS field that renders literal asterisks and heading hashes because the Markdown came along for the ride. This tool takes a paste, shows you what it found, and hands back clean plain text. The value is in the breadth of what it normalises rather than in any single clever feature: invisible characters removed, whitespace collapsed sensibly, punctuation converted back to plain ASCII equivalents where that is what you want, line breaks repaired, and formatting syntax stripped so prose arrives as prose. It is free, needs no account, and is fast enough to sit permanently in a browser tab as the last step before publishing. Honest limits: it is a utility with a narrow job and no ambitions beyond it. It will not edit or improve your writing, and it should not be treated as a way to hide that text was AI-generated — character stripping is not a reliable defence against detection, and using it that way misreads the tool. For its actual purpose — making sure what lands in your CMS, spreadsheet, email tool or codebase is exactly the characters you intended — it removes an entire class of invisible bugs in a couple of seconds.
