What is OSHI Messenger?
OSHI is an encrypted messenger that keeps working when the network does not. Nearby phones relay for each other over Bluetooth mesh and LoRa, so a conversation keeps moving in airplane mode, underground, or during an outage. No phone number, no account, no SIM. One-to-one chats are end-to-end encrypted with a Double Ratchet, and you can verify any contact with a safety number. Offline maps, steganography, and an on-device AI that never sends a word off your phone. Free and open source, MIT.
