offChat is a private off-grid mesh messenger for moments when the internet fails—or when you simply don’t want your conversations to depend on the cloud.
Instead of routing everything through central servers, offChat builds a local mesh between nearby devices using Bluetooth and Nearby discovery. Text and push-to-talk voice travel across your physical perimeter, with local storage and user-controlled privacy at the core.
PRIVATE CONNECTIVITY WITHOUT THE INTERNET
offChat’s foundation is peer-to-peer mesh communication: discover nearby devices, start conversations, and keep the channel alive without Wi‑Fi or mobile data. Built for remote areas, events, emergencies, and any environment where carriers drop out.
MESH CHAT & PEER DISCOVERY
• Smart discovery of nearby devices
• Bluetooth LE and Classic in the mesh flow
• Hybrid transport to keep conversations resilient
• Local message history stored on your device
OFFLINE VOICE (PTT)
• Push-to-talk voice without relying on the internet
• Audio pipeline tuned for mesh transmission
• Intelligent retry and fragmentation for tough RF conditions
PRIVACY BY DESIGN
• Encryption in the messaging path
• Secure storage for sensitive data
• Biometric unlock when your device supports it
• Extra protection against unwanted screen capture in sensitive contexts
• Clear permission onboarding (Bluetooth, location for discovery, and related access)
IDENTITY & JOINING THE MESH
• QR pairing and auxiliary scan flows
• Phone contacts integration (with permission)
• Optional verification layers (Gate 2FA / sign-in when enabled)
OPTIONAL ONLINE BRIDGES
When connectivity returns, offChat can optionally extend the experience with bridges such as Nostr and Lightning features—without turning the app into an always-online messenger. The center of gravity remains the local mesh.
WHO OFFCHAT IS FOR
• People who need resilient off-grid communication
• Field teams, events, and low-signal environments
• Users who value privacy, autonomy, and local data control
