ChatterBox: Text Securely Off-Grid

  • Independent of infrastructure & centralized services (cell/internet/grid)

  • Local messaging, broadcasts, & location sharing with trusted people

  • Smart decentralized mesh algorithm intelligently moves packets as efficiently as possible, while maintaining security

  • Out-of-range / powered-off devices can receive messages up to 24 hours later

  • Encrypted and digitally signed (asymmetric/symmetric encryption + ECDSA)

  • Delivery confirmations when a message is received

  • Unpredictable frequency hopping + packet striping across frequencies

Using ChatterBox

ChatterBox is designed for anyone to be able to just pick up and use, intuitively. You don’t need to understand encryption, RF, configure a bunch of settings, or have an amateur radio license. You don’t need any app or phone!

Transfer SD Card Between Devices

If you are using SD cards (recommended), you can move a T-Deck’s SD card over to a pager (and vice versa). It will carry over all settings, messages, and password protection.

How ChatterBox Delivers

Even to Powered Off Devices

Broadcast: Message blasts securely across your cluster

Direct: Instant via RF (LoRa)

Mesh: Your cluster works together

Technical

Good place to start if you want to know more.

All messages, locations, and other sensitive information is encrypted during transmission and at rest

All transmitted information is digitally signed, including messages, locations, pings, and delivery confirmations.

Both use LoRa, send messages, and utilize some of the same hardware. That’s where the similarities end.

For enhanced security and anti-jamming, ChatterBox clusters/channels hop unpredictably.
