TextWash

Detect and remove hidden AI watermarks, invisible characters, smart punctuation and Markdown residue — 100% locally. See and remove hidden AI fingerprints and "tells" in any text: invisible watermark characters, machine typography, and clichés. 100% on-device. Privacy-focused: No data is collected or transmitted.

TextWash x-rays your text for the fingerprints AI assistants leave behind — then washes them out in one click.

WHAT IT DETECTS

• Invisible Unicode watermarks: zero-width spaces, narrow no-break spaces (U+202F, the famous ChatGPT tell), soft hyphens, byte-order marks and 30+ more
• Machine typography: curly quotes, em dashes, real ellipsis characters, fullwidth and lookalike letters (fake Unicode "bold")
• Markdown residue from chat apps: **bold** markers, # headers, [links](url), backticks
• 200+ AI cliché phrases ("delve", "a testament to", "key takeaways") in English, Spanish, French, German, Portuguese and Italian — flagged, never auto-rewritten, so the fix stays in your voice
• Lookalike Cyrillic/Greek letters hiding in Latin text
• An AI slop grade from A+ to F, based on fingerprint density

Character-level detection works in every language.

HOW IT WORKS Paste text into the popup. The fingerprint report lists every finding by name and Unicode code point, the x-ray view shows exactly where each hidden character sits, and one click removes all the technical fingerprints. Copy the clean text and go.
