GhostInk

GhostInk is an open-source emoji steganography tool that lets you hide secret text within emojis using Unicode Tag Characters (U+E0001–U+E007F). The hidden data is completely invisible and the emoji looks identical to the original, making it a powerful way to conceal information in plain sight.

Built with a Flask/Hypercorn backend and React frontend and both bridged with vite-fusion (the same technology that powers HomeDock OS), GhostInk provides a sleek interface for encoding, decoding, and managing hidden messages. It supports authentication, rate-limited access, and secure session handling, making it suitable for both personal use and self-hosted deployments. Don’t believe us?

GhostInk also includes pre-built examples to help you understand how steganography works, along with educational content about tag character functionality and platform compatibility. Your encoded emojis survive on platforms like Twitter/X, Signal, and Email, while platforms like Telegram and Discord may strip the hidden data. It’s the perfect blend of privacy, education, and… fun. Who said prompt injection?
