Paste text from ChatGPT, Word or a web page. Invisible characters are removed, odd spaces and quotes are made plain, and you get a list of everything that changed.
Why clean text?
Text copied from AI chat tools, word processors and web pages often carries characters you can't see - zero-width spaces, byte order marks, direction marks, non-breaking spaces. They break code, form validation, search and spreadsheets. Curly quotes and long dashes are also common tells that text was pasted in. Everything here runs in your browser; nothing you paste is sent anywhere.
