AI Text Cleaner
Strip invisible Unicode characters, smart quotes, and em dashes from AI-generated text — free and processed entirely in your browser.
About the AI Text Cleaner
Text copied from ChatGPT, Claude, or Gemini often carries hidden baggage — zero-width spaces, non-breaking spaces, and byte-order marks that are invisible on screen but break string matching in code, corrupt CSV imports, and can make writing read as obviously AI-generated. Different AI tools leave different fingerprints: heavy em dashes and curly quotes are common giveaways.
This tool scans your text for invisible Unicode characters and typographic substitutions (smart quotes, em dashes, non-breaking spaces) and lets you clean up exactly what you choose — with a preview showing what changes before you copy the result. Everything runs locally in your browser; your text is never uploaded to a server.

Frequently Asked Questions
What exactly counts as an "invisible character"?
Characters like zero-width spaces, zero-width joiners, non-breaking spaces, and byte-order marks — they render as nothing on screen but are still present in the text, and can break code that does exact string matching, corrupt CSV/JSON imports, or trip up plagiarism and AI-detection tools that look for these patterns.
Will this remove em dashes and smart quotes too?
Yes, as an optional toggle — smart/curly quotes (“ ”) get converted to straight quotes ("), and em dashes (—) to regular hyphens, both common typographic patterns AI writing tools favor.
Will this change the actual wording of my text?
No — this only removes invisible characters and normalizes punctuation style. No words are added, removed, or reworded.
Is my text uploaded anywhere?
No. Cleaning happens entirely in your browser.
