## What is UNDERMASK Text Clean?

AI chats leave invisible characters and formatting leftovers in the text you copy. They break layouts, mess up search, and travel with your text wherever you paste it. Text Clean finds them and removes them in one tap.

HOW IT WORKS
- Paste your text — the app instantly shows how many hidden characters it found.
- Tap Clean — see exactly what was removed.
- Copy, share to any messenger, or save as a file.

WHAT IT REMOVES
- Invisible characters: zero-width spaces and joiners, word joiners, byte order marks, soft hyphens
- Hidden tag characters that can carry invisible text
- Text direction controls
- Non-standard spaces, such as non-breaking and narrow spaces
- Extra whitespace: trailing spaces and long runs of empty lines

Emoji stay intact, including family emoji and flags. Text Clean does not rewrite your words.

PRIVATE BY DESIGN
Cleaning happens entirely on your phone. No account, no server, no analytics, no tracking. Your text never leaves your device.

FREE AND PRO
Free: 5 cleans a day for texts up to 10,000 characters. Cleaning text that is already clean doesn't count.
Pro, a one-time purchase: unlimited cleans of any length, extra rules (remove Markdown, straighten quotes, replace long dashes and ellipsis), and saving as a .txt file. No subscription.
