CleanPaste is a lightweight, open source, clipboard cleaning extension that removes hidden characters and formatting artifacts from copied text before you paste it somewhere else.

Use CleanPaste when text copied from websites, AI chats, documents, or other applications carries unwanted formatting, strange spacing, invisible characters, or other copy-and-paste artifacts.

Features

• Clean the text on your clipboard in one click
• Replace the clipboard with plain text, so what you paste arrives unformatted
• Remove zero-width and other invisible characters
• Normalize unusual Unicode spacing, stray tabs, and trailing whitespace
• Tidy inconsistent line endings and excessive blank lines
• Paste text into the extension manually and copy back a cleaned version
• Local processing: your text never leaves your device
• Simple, keyboard-friendly interface with no account and no setup

What it keeps intact

• Your actual writing completely unchanged
• Curly quotes, apostrophes, em dashes, and ellipses
• Accents, emoji, and non-English alphabets
• Normal paragraph structure

CleanPaste is useful for preparing text before pasting into email, documents, forms, content-management systems, social media, and other applications.

It can also help with formatting artifacts in text copied from AI chat tools, but CleanPaste is a text sanitizer and formatting cleaner: it does not claim to remove AI watermarks or to defeat AI detection.

CleanPaste focuses on one thing: turning copied text into clean, usable plain text quickly.
