Encrypt a message inside a known work of writing or art. Share the key separately.
Write what only your recipient should read.
A real, credited work is selected in this style.
A credited artwork matched to this style is selected.
Automatic selection avoids repeats on this device until the group cycles.
Use only an image you have the right to modify and share. Famous photos and modern art are not automatically free to reuse.
Known, credited writing is the default. Paste an article only if you have permission to reuse it.
Choose your own excerpt above. Copying only the visible text loses the hidden data.
The PNG is assembled in your browser. Hiding is experimental and may fail after resizing or posting. Keep the original PNG and test any published copy.
A random 256-bit key is ready; you can replace it with your own. Save it and share it separately. Your message and key go to the hidden.irish server for encryption; we do not store them.
Paste the encoded text or choose a hidden.irish PNG, then enter the shared key.
Paste the complete text. If another app removes invisible characters, use the portable encrypted token instead.
The image stays on your device. Only its recovered encrypted token and the key are sent to hidden.irish for decryption.
The visible writing carries your encrypted message. Use Copy complete text to include the invisible part.
Your finished message will appear here after you press the seal.
The picture carries encrypted data. Do not crop it, screenshot it, or resave as JPEG; hiding is experimental.

Use this if hidden data is lost. The token is encrypted but visible, not concealed. Share the key separately.
Save and send the key through a separate channel. Anyone with the key and encoded text or image can read the message.
Use your own OpenAI API key only for explicitly selected original writing or paid image generation. Known works need no AI key. OpenAI never receives your secret message, decoding key, or encrypted token.
The key stays only in this tab's memory and is sent to hidden.irish only when you choose AI generation. It clears when you reload or close the tab. Saving it does not verify it with OpenAI.
