Jack Dorsey Launches Bitchat, a Bluetooth Messaging App That Works Without Internet
Jack Dorsey, Twitter’s co-founder and former CEO, has officially launched Bitchat, an innovative new messaging app that functions entirely via Bluetooth mesh networks—no internet, SIM cards, or servers required. Now in beta via TestFlight, Bitchat is designed to support private, encrypted, and decentralised communication, especially in regions facing internet shutdowns or surveillance.
What Is Bitchat?
Bitchat is a peer-to-peer messaging app that allows users to communicate across Bluetooth-connected devices, forming temporary clusters that can pass messages locally. Messages can also travel farther through “bridge devices” that relay them across overlapping clusters, creating a mesh network.
It’s a major leap in offline messaging and reflects Dorsey’s long-standing support for censorship-resistant, privacy-first platforms, such as Damus and Bluesky.
“It’s a personal experiment in Bluetooth mesh networks, relays, store-and-forward models, and encrypted messaging,” said Dorsey.

Why Bitchat Matters
Bitchat’s unique offline architecture makes it ideal for use during internet blackouts, natural disasters, or in areas under strict censorship. By eliminating the need for central servers or personal identifiers, Bitchat prioritises user privacy, decentralisation, and freedom of expression.
With growing global concerns around surveillance and digital rights, Bitchat enters the scene as a bold new approach to offline, encrypted communication.
