Clean paste tool for AI output: remove invisible Unicode and markdown.
Clean Paste AI strips invisible Unicode spaces, zero-width characters and leftover markdown from AI output before you paste it into docs, a CMS or email. It shows exact residue counts, runs locally in your browser and the free cleaners need no login. Paste text from ChatGPT, Claude or Gemini, inspect what is hidden, then clean it in one click. Free tools cover invisible characters and markdown; Pro adds a text watermark remover and a rewrite humanizer. It keeps formulas, search indexes and document typography from breaking.
