Wrote it yourself and still worried about getting flagged? See the mechanical tells AI detectors key on — hidden characters, machine punctuation, formatting residue — and strip them before you hit submit.
🔒 100% private — your text never leaves this browser tabAI detectors get human writing wrong often enough that most vendors publish a false-positive rate — and some of those false positives are purely cosmetic. Word processors auto-replace your straight quotes with curly ones and your double hyphens with em dashes. Grammarly and Docs suggestions insert professional typography. A quote pasted from a website drags invisible Unicode characters — zero-width spaces, non-breaking spaces — into your document, where they survive every subsequent copy-paste. None of this means you used AI. All of it makes your essay look machine-produced at the character level, because these are exactly the artifacts AI output is full of.
Paste your essay above. The fingerprint report names every suspicious character by its Unicode code point, the x-ray view shows exactly where each one hides, and the grade tells you how machine-flavored the text reads overall. Then one click washes out the mechanical tells: invisible characters deleted, curly quotes straightened, em dashes and real ellipses converted to what a keyboard actually types, stray Markdown symbols stripped. Your words are never touched — the diff view proves it. And because everything runs locally in your browser, your unsubmitted coursework is never uploaded anywhere.
TextWash is not an AI detector and not a "humanizer." It won't tell you whether a detector will pass your essay, and it won't make AI-written text undetectable — statistical detectors read word choice and sentence rhythm, which no character-level tool can change (and which we deliberately don't try to disguise). What it does is narrower and honest: it removes the mechanical artifacts that can get hand-written work flagged for cosmetic reasons — the same evidence your grader can see. If you wrote the essay, this is housekeeping, not deception. Keep your drafts and version history too — they're the strongest proof of authorship there is.

No, and it doesn't try to. TextWash removes mechanical fingerprints — hidden characters, machine typography, formatting residue. Statistical detectors also analyze word choice and sentence rhythm, which no character-level tool changes. If AI wrote your essay, this won't disguise it; if you wrote it, this removes the cosmetic artifacts that trigger unfair flags.
Detectors are statistical and have documented false-positive rates — formulaic prose, non-native English and heavily edited text all get misread. On top of that, Word, Google Docs and Grammarly insert curly quotes, em dashes and hidden Unicode characters that make hand-typed text look machine-produced at the character level. TextWash shows and removes that second, fixable category.
