What does the Clean tab remove from my text?

Zero-width characters (sometimes used to invisibly watermark AI-generated text or hide characters in pasted content), other invisible control characters, extra spaces and blank lines, and curly quotes normalized to straight quotes.

What does the Compare tab do?

A line-by-line diff between two blocks of text, highlighting what was added and what was removed.

Does my text get uploaded anywhere?

No — both cleaning and comparing run entirely in your browser.

Text Tools

Toolsda's Text Case Tools strip zero-width characters and other invisible marks sometimes used to hide watermarks in AI-generated or pasted text, fix spacing and curly quotes, and diff two versions of text line by line. Both Clean and Compare run entirely in your browser — nothing is uploaded.
