Jack Dorsey Makes a New Chat App Called Bitchat— No Internet or Phone Number

What if you could send messages to your friends without using internet, data, or even a SIM card? Sounds impossible, right? Well, Jack Dorsey, the man who co-founded Twitter and now runs Block has just made it possible with a brand-new messaging app called Bitchat.

This isn’t your regular chat app. Bitchat doesn’t need mobile networks, WiFi, usernames, or even your phone number. I

Instead, it uses something called Bluetooth mesh networks. That means your phone can connect with nearby phones and pass messages along like a digital relay race even when you’re offline.

Why Bitchat is a big deal

Jack Dorsey announced the launch of Bitchat on July 6, 2025, calling it a personal experiment but it’s already creating serious buzz. Unlike WhatsApp or Telegram, which rely on servers and internet connections, Bitchat skips all of that.

It’s designed for privacy, freedom, and connection, especially in places where the internet is restricted, expensive, or completely shut down.

This app doesn’t just send messages from one phone to another. It also allows your phone to quietly join a group of nearby phones and pass messages from one to the next, forming a kind of invisible local network. 

If someone you’re trying to reach is too far away, another user nearby can help carry the message forward, like a digital messenger.

It is built for privacy and tough times

Every message on Bitchat is encrypted and temporary, it disappears by default, and nothing is stored on a central server. 

This means there’s no big tech company watching what you say or storing your conversations. It’s perfect for people who care about privacy, live in areas with internet restrictions, or just want a simple, secure way to stay in touch.

Bitchat also lets users create password-protected group chats called “rooms” and plans to add even more features like WiFi Direct to improve speed and range in the future.

Not just another app war

Dorsey’s move with Bitchat isn’t happening in isolation. Around the same time, Elon Musk announced xChat, a rival messaging tool under the X platform (formerly Twitter). 

While xChat focuses on encryption, disappearing messages, and audio/video calls, it still works within the usual internet setup. Bitchat, on the other hand, is going completely off-grid.

And while WhatsApp is still the king of messaging apps worldwide, it’s making changes too like introducing per-message charges for businesses starting this July. So as tech giants battle over the future of messaging, Dorsey is quietly building a new path, one that doesn’t rely on cables, towers, or even your SIM card.
