What is an AI watermark remover?
An AI watermark remover is a free tool that strips invisible characters and giveaway formatting from AI-generated text. AI tools and word processors add characters you cannot see: zero-width spaces, byte-order marks, curly "smart" quotes, em dashes, and non-breaking spaces. These quietly mark your copy as machine-generated and break formatting when you paste it elsewhere.
TextUnmark scans your text, removes every one of these characters, and returns clean copy with a full report of what changed. Your words and meaning stay exactly the same.
Invisible characters
Zero-width spaces, joiners, BOMs, soft hyphens, and directional marks are all removed.
AI buzzwords
Words like "delve," "leverage," and "seamless" are swapped for plain language.
Correct dashes
An em dash between words becomes a comma, and a number range becomes a hyphen.

What TextUnmark removes
Here is exactly what the tool cleans from your text:
- Zero-width characters: zero-width space, zero-width non-joiner, word joiner, and byte-order marks.
- Formatting marks: soft hyphens, directional marks, and directional isolates.
- Smart quotes: curly single and double quotes and guillemets become straight quotes.
- Dashes, done correctly: an em dash between words becomes a comma, a range between numbers becomes a hyphen, and any leftover dash becomes a plain hyphen. The spacing and capitalization are fixed so the sentence still reads right.
- AI buzzwords: overused words like "delve," "leverage," "utilize," "seamless," and "robust" are swapped for plain words, and filler openers like "It's important to note that" are dropped.
- Spaces and ellipses: non-breaking and exotic spaces become a normal space, and the ellipsis character becomes three dots.
Emoji, including multi-character emoji sequences, are left fully intact. You paste, we handle the rest, and you get a report of exactly what changed.
