GhostInk - Hide Text in Emoji Hide secret messages inside any emoji using Unicode steganography. The emoji looks completely normal before and after encoding — nobody can tell there's a hidden message just by looking at it. HIDE IN PLAIN SIGHT Pick any emoji as your carrier, type your secret message, and tap Encode. The result looks like an ordinary emoji you can paste anywhere: chats, posts, captions, notes. No one will ever suspect it carries a hidden message. Your secret travels invisibly, hidden in plain sight where nobody thinks to look. HOW IT WORKS GhostInk encodes your text into invisible Unicode tag characters and attaches them directly to your chosen emoji. The emoji passes through any messaging app or platform completely untouched. The recipient simply pastes it into GhostInk and taps Decode to reveal the secret instantly. No special setup, no accounts, no shared keys needed. YOUR PRIVACY, GUARANTEED Everything happens entirely on your device. No servers, no accounts, no cloud processing of any kind. Your secrets never leave your iPhone. We collect zero data — no tracking, no analytics, nothing at all. GhostInk was built from the ground up with privacy as its core principle.
