A message within a message

The safest and most invisible way
to protect your messages.

Perfectly Invisible

Hidden messages are invisible in any environment. Only the visible text shows up, even when copied and pasted.

Privacy Protection

The hidden content does not exist in its original form anywhere in the text. No analysis tool can find it.

Zero-Knowledge Security

We cannot read your messages. Your original text and password are never stored, and without the password, no one — not even LiterMark — can decrypt them.

How to use it

Deliver secret messages securely in just 3 simple steps.

1

Enter a visible text and a secret message

Type the text others will see and the message you want to hide.

2

Encrypt the message

The secret message is encrypted through multiple layers and embedded into the text.

3

Copy and send anywhere

It looks like ordinary text, but entering the password reveals the hidden message.
