Twitter Co-founder launches Bitchat: A private messaging app that works without internet

Twitter co-founder Jack Dorsey has launched a new messaging app called Bitchat that works entirely without the internet. The app uses Bluetooth mesh networking to let users send end-to-end encrypted messages without needing mobile data, SIM cards, or Wi-Fi. There is no need to sign up, create usernames, or store messages, making it a privacy-first tool for communication. Users can send temporary messages, create group chats, join password-protected rooms, and chat without revealing their identity. Bitchat is especially useful in situations where internet access is limited or blocked, such as during emergencies or in regions with censorship. The app is entering a competitive space that includes other mesh-based platforms like Fernweh, which also offers offline messaging and crypto payments. While Fernweh focuses on more features, Bitchat keeps things simple and secure. The app reflects a growing trend toward decentralized, private communication in a world increasingly concerned with digital surveillance.
