Paste the complete passage
Keep the full paragraph and list context. Very small snippets can hide whether a space, line break, list marker, or code fence is actually part of the intended structure.
Clean Claude text for a reliable paste
Turn text copied from Claude into predictable plain text by removing hidden Unicode artifacts, strange spaces, and optional Markdown formatting.
A paste problem is usually a format mismatch
- The destination may treat Markdown headings, emphasis, links, tables, and code blocks as syntax or as literal characters.
- Unicode punctuation and spaces can be typographically correct in one editor and inconvenient in a legacy field, database export, or publishing tool.
- Copying through several apps can introduce line-ending changes, non-breaking spaces, tabs, or invisible control characters.
- Removing every invisible code point without review can damage emoji sequences, right-to-left text, or scripts that rely on joiners.
Clean the text without losing control.
Inspect before stripping
The cleaner inventories suspicious code points and shows their names and counts. This makes a hidden-character problem visible without sending the text to a detection service.
Match the mode to the destination
Use Essential for another rich editor, Plain text for fields that should contain words and paragraphs only, and Deep clean only when a strict system rejects format characters.
Copy the verified result
Read the output, check names, URLs, quotations, emoji, code, and right-to-left passages, then use Copy clean text. The tool reports clipboard denial without deleting the result.
Know what the cleanup can prove.
Predictable paragraphs
Normalize carriage returns, line separators, unusual blank space, and trailing whitespace so the destination receives a stable text string.
Optional plain formatting
Simplify common Markdown and raw HTML while retaining readable link destinations, list content, headings, and code text.
Private cleanup
The page does not fetch a model, upload the content, or keep a browser draft. The work disappears on reload.
Keep formatting and provenance separate.
This page does not claim that Claude adds a specific invisible watermark to ordinary copied responses. Formatting artifacts can come from the source, the browser, an intermediate editor, or the destination. The report describes only the characters and patterns found in the text you provide.
Common questions, answered plainly.
Does Claude add zero-width spaces?
This tool does not assume a source-specific behavior. It scans the text you paste and reports zero-width spaces only when they are actually present.
What should I use for a CMS?
Start with Plain text when the CMS has its own formatting controls. Use Essential when the CMS accepts Markdown and you want to keep headings, links, lists, and code markers.
Why is Deep clean optional?
Some invisible characters carry real linguistic or emoji meaning. Deep clean is available for strict technical destinations, but it warns you to review the result carefully.
Paste the text. See every fix.
Use the same canonical cleaner for hidden characters, unusual spaces, Markdown, HTML, smart punctuation, and clean plain-text copy.
Make copied text useful without making false promises.
Clean what is present, review what changed, and preserve any disclosure or editorial record the work still needs.
