Free AI Text Cleaner

Text copied from ChatGPT, Claude or Gemini can carry invisible characters that break code, fail form validation, or silently change a string comparison. Paste it here, see exactly what is hiding in it, and get a clean copy back.

Privacy Level 1 — 100% local: your files never leave your browser

Free plan: unlimited text, no signup. Cleaning runs entirely in your browser — safe for proprietary code, client deliverables and config files. Your wording is never changed; only invisible characters and, if you tick it, smart typography are normalized.

Pasted text

What to clean

Remove zero-width characters Zero-width space, non-joiner, joiner, BOM, word joiner, soft hyphen. Note: removing the zero-width joiner can split joined emoji — untick this to keep emoji sequences intact.

Replace special spaces with a normal space Non-breaking, narrow no-break, figure, ideographic and other look-alike spaces.

Remove bidi / directional marks Left-to-right and right-to-left marks and embeddings that can reorder displayed text.

Remove control characters C0/C1 controls except tab and line breaks, which are always kept.

Remove variation selectors Invisible selectors that change how the previous character renders.

Normalize smart typography Curly quotes to straight quotes, em/en dashes to hyphens, ellipsis character to three dots. Off by default: this changes visible characters.

Frequently asked questions

Where do hidden characters come from?

Chat interfaces, word processors and web pages insert them to preserve rich-text formatting during copy operations: zero-width spaces, narrow no-break spaces, soft hyphens and directional marks travel with the text silently, then misbehave in a code editor, a CMS or a database field.

Does cleaning change my wording?

No. With the default options only invisible characters are removed and look-alike spaces become normal spaces. Smart typography normalization is a separate, off-by-default option because it changes visible characters.

Will this break my emoji?

Possibly, if you leave zero-width removal on: joined emoji (for example a person plus a laptop) are glued together with a zero-width joiner. Untick the zero-width option to keep emoji sequences intact while still cleaning everything else.

Is my text uploaded?

No. Scanning and cleaning run on the textarea value in your browser. Close the tab and the input is gone.
