Remove invisible characters, smart quotes, and em dashes from AI-generated text — 100% in your browser, nothing uploaded
Text generated by ChatGPT, Claude, Gemini, and other large language models — or copied out of Word, Google Docs, and web pages — is almost never as plain as it looks. It's quietly littered with characters you can't see: zero-width spaces, byte-order marks, non-breaking spaces, direction marks, and "smart" typography like curly quotes, em dashes, and single-glyph ellipses. Those artifacts are harmless until they aren't: they break string matching in code, corrupt CSV imports, throw off word counts, render as strange symbols in plain-text fields, and make writing visibly read as machine-generated. This AI Text Cleaner strips all of it in one paste, and — crucially — does the entire job inside your browser, so the text you're cleaning is never uploaded, stored, or logged anywhere. The tool breaks the cleanup into individual rules you control. Invisible and zero-width characters are removed outright; non-breaking and unusual Unicode spaces collapse to a normal space; curly single and double quotes become straight ASCII quotes; em and en dashes become hyphens; the ellipsis glyph becomes three dots. Two optional rules go further — stripping Markdown formatting (bold, italics, inline code, headings, and bullet markers) and trimming trailing spaces while collapsing runs of blank lines. Every rule is a toggle, and as soon as you paste, the tool reports exactly how many of each artifact it found, so you're never trusting a black box. A developer pasting an API key or config value that mysteriously won't match can spot and strip an invisible zero-width space in seconds. A writer or student who drafted with an AI assistant can remove the em dashes and curly quotes that make the prose read as obviously generated before submitting it. A marketer moving copy from a doc into a CMS or email platform can flatten smart punctuation so it renders correctly across every client instead of turning into mojibake. In each case the fix is one paste and a click. One deliberate note on honesty: this tool cleans formatting and hidden characters — it does not "bypass AI detectors," rewrite your sentences, or make machine-written text pass as human, and we won't pretend otherwise the way some similar tools do. It's a precise, transparent text-hygiene utility. Because everything runs locally with no server round-trip, it's fast, works offline once the page has loaded, requires no account, and keeps even sensitive text entirely on your own device.
100% private — your text is cleaned in your browser and never uploaded to any server.
100% in your browser — Every rule is a local string operation — your text is never uploaded, stored, or logged, so it's safe for sensitive drafts and client work.
Itemized detection report — See exactly how many invisible characters, smart quotes, em dashes, and odd spaces were found — not a black-box 'cleaned' with no detail.
Granular toggles — Turn each cleanup rule on or off independently, so you strip only what you want and keep the rest of your formatting intact.
Honest by design — It cleans formatting artifacts and hidden characters — it does not claim to 'bypass AI detection' or rewrite your words, unlike many similar tools.
