What is copied

What gets fixed
When text only looks clean
The report uses exact character names for proof. These plain-English descriptions explain why each one matters.
U+202FSpaces that are not spaces
They look ordinary, but can change line wrapping. A special space does not prove where text came from.
U+200BCharacters you cannot see
They can sit inside a word, email address, or code snippet and break search or matching.
U+2014Quotes, dashes, and punctuation
Smart quotes, long dashes, and ellipses can be changed to plain keyboard punctuation.
U+00A0Text that pastes badly
Special spaces can create odd gaps or stop a sentence from wrapping onto the next line.
U+E0000Hidden information
Some invisible characters can carry extra data without adding anything you can see.
MD → TXTMarkdown to plain text
Strip common heading, bold, and link syntax while preserving list structure and punctuation.
How it works
Paste. See what changed. Copy.
- 01
Paste
Add text from an AI chat, document, email, PDF, or webpage.
- 02
Check
See every hidden character, what it was called, and whether it was removed or replaced.
- 03
Copy
Use the same words again, now without the invisible clutter.
What it does and does not do
It fixes hidden characters and formatting
Strange spaces become normal spaces. Invisible marks are removed. Quotes, dashes, and leftover formatting can be standardized.
It never rewrites your ideas
It does not paraphrase, fact-check, or promise to fool AI detectors. It cleans the characters underneath your words and stops there.
Common destinations
Clean it once. Paste it anywhere.
Publishing
Publish drafts in a CMS without strange gaps, surprise Markdown, or lines that refuse to wrap.
Publishing guideCode and data
Remove invisible characters that can break email addresses, JSON, CSV imports, search, and code comparisons.
Developer guideDocuments and teams
Move text into Word, Google Docs, Notion, email, and support tools without carrying the mess with it.
Pasting guideCommon questions
Straight answers
Is my text safe?
Yes. Your text stays on your device. The cleaner runs inside your browser and never uploads, logs, or stores what you paste.
Can this remove AI watermarks from ChatGPT text?
It can remove supported hidden Unicode characters and normalize special spaces in copied text. Finding those characters does not prove that text is AI-generated or watermarked. Statistical watermarks such as SynthID-Text work through word choice and cannot be checked or removed by this character cleaner.
Does cleaning make AI text undetectable?
No. AI detectors analyze word patterns and sentence statistics, not hidden characters. This tool fixes formatting and strips hidden characters — it never rewrites your words.
Does this use AI?
No. A fixed set of cleaning rules runs on your device. No AI model or external service ever sees your text, and the same settings always produce the same result.
Why does text paste weirdly in Notion or Google Docs?
Websites, PDFs, documents, and AI chats can add special spaces or invisible marks when you copy. Those characters can create odd gaps, broken line wrapping, or text that search cannot find.
Can I use this offline?
An already-open cleaner can process text without an internet connection. Opening a page again while offline depends on your browser cache; bookmarking it alone does not guarantee offline access.
