AI Text Cleaner
Paste text from ChatGPT, Claude or Gemini and remove the formatting debris in one step: em dashes, curly quotes, invisible characters, Markdown symbols and messy spacing. Your words stay exactly as they are.
What the cleaner fixes
Em and en dashes
A dash between words becomes a comma, or a period when a new sentence starts. Number ranges like 5–10 become 5-10.
Curly quotes
Typographic quotes and apostrophes become plain straight ones, so the text behaves the same in every editor, form and code block.
Hidden characters
Zero-width spaces, word joiners, soft hyphens and non-breaking or thin spaces are removed or turned into normal spaces.
Markdown symbols
Chat tools format answers with **bold**, # headings and `code`. Pasted into an email or document, the symbols show up as clutter. The words stay.
Spacing
Double spaces, trailing spaces, extra blank lines and the single-character ellipsis are tidied up.
Cleaning formatting is not the same as rewriting
Clean formatting makes AI-assisted text easier to paste into emails, documents, forms and websites. It does not change how the writing reads. Sentences that sound generic, repetitive or overly formal still sound that way after the dashes are gone.
If the wording itself needs work, the WriteHumanly humanizer rewrites it to sound natural while keeping your facts, names and numbers. To check how a passage reads to a detector, use the free AI detector.
A note on watermarks: OpenAI, Google and Anthropic have described text watermarks that work through patterns in word choice. Those are not characters in the text, so no cleaner can remove them, and this tool does not try to.
Frequently asked questions
Does this remove ChatGPT or Claude watermarks?
No. The watermarks OpenAI, Google (SynthID) and Anthropic use are statistical patterns in which words a model picks, not hidden characters, so no character cleaner can remove them. This tool fixes formatting: dashes, quotes, invisible characters, Markdown and spacing.
Is my text uploaded anywhere?
No. The cleaner runs entirely in your browser. Nothing you paste is sent to a server or stored.
Why does AI text have so many em dashes?
Chat models learned from edited, formal writing where em dashes are common, and they lean on them to join clauses. In everyday writing most people use commas, periods or parentheses instead, so a page full of em dashes stands out.
What are hidden characters in AI text?
Characters you cannot see but that change how text behaves: zero-width spaces, word joiners, soft hyphens and non-breaking or thin spaces. They can break word counts, search, form fields and code. Copying from chat interfaces and documents sometimes brings them along.
Will cleaning the text change my wording?
No. The cleaner only changes punctuation, symbols and spacing. Every word stays as you wrote it. To make the wording itself sound more natural, use the WriteHumanly humanizer.
