Hide Messages in Plain Sight
Phasm uses steganography to hide secret text messages inside ordinary JPEG photos. Two modes, zero servers, total privacy.
Two Modes. One Mission.
Different threat models need different tools. Phasm gives you both.
Ghost Mode
Stealth embedding that resists forensic detection. Your message stays invisible even under steganalysis.
Armor Mode
Robust encoding that survives JPEG recompression and cropping. Share images freely without losing the hidden message.
End-to-End Encrypted
Messages are encrypted with AES-256 before embedding. Everything happens on your device—nothing is sent to a server.
