Frequently Asked Questions
Can hidden characters be dangerous?
Most are harmless formatting artifacts, but a few — like directional overrides — have been used to disguise file names or spoof how text displays. Scanning helps you tell the difference.
Does this tool store or upload my text?
No. Scanning happens entirely in your browser — nothing you paste here is sent anywhere or saved.
What is a Right-to-Left Override attack?
It’s a trick that uses a hidden character to reverse how following text is displayed, making a file or message appear different from what it actually is.
Why does my pasted text show characters I never typed?
Copying from certain apps, websites, or messaging platforms can silently carry over invisible formatting characters along with the visible text.
Can I scan a whole document, or only short text?
You can paste text of any length — usernames, messages, or full paragraphs all work the same way.
