Clean Paste is a free, browser-based tool that instantly removes invisible characters, hidden metadata, and AI watermarks from text. It requires no sign-up, no payment, and imposes no usage limits — just paste and clean.
What is Clean Paste?
Clean Paste is an online text cleaner that scans pasted content for zero-width spaces, invisible formatting marks, and AI-generated watermarks, then strips them to produce clean, natural-looking text. It runs entirely in the browser at cleanpaste.org and is built by an independent team (no company name is disclosed on the site). Input is any text containing hidden artifacts; output is the same text with those artifacts removed.
