A Windows or Linux PC joins the same nearby Bluetooth chat as the official bitchat phones. No account, no phone number, no installer. Send private messages, photos, and voice notes. It keeps running in the tray after closing the window. Independent and open source, not the official app.

Could you build this?

Partial The UI and tray behavior are easy to vibe-code, but a real client must join the bitchat Bluetooth mesh and interoperate with the official phone app. That requires implementing the protocol and BLE on desktop, which is much harder.

What it would actually take: Study the bitchat protocol (packet format, Noise-based encryption, relay and TTL rules) from its open-source code, then implement a BLE central and peripheral stack on Windows and Linux (WinRT or BlueZ). The hard parts are reliable BLE mesh behavior across OS Bluetooth stacks and byte-exact protocol compatibility with the phone app. This requires networking and cryptography expertise and extensive on-device testing.
