Features & Capabilities

Calls that stay in sync: latency can no longer pile up. If the line gets congested, OSHI now drops old audio instead of falling behind by seconds.

OSHI is a free, open-source encrypted messenger built in Switzerland for people who refuse to depend on cell towers, big tech, or anyone's permission to communicate. Whether you're hiking off-grid, traveling abroad, preparing for an emergency, or just done with surveillance — OSHI keeps you connected, oriented, and informed without ever needing a signal.

SURVIVAL-READY — OFFLINE

  • Mesh networking via Bluetooth and Wi-Fi Direct — message anyone within range, no internet, no SIM, no cell tower
  • Multi-hop relay so messages travel through nearby OSHI users
  • Built-in offline maps for 42 European countries + cities worldwide
  • Turn-by-turn navigation with car, walking, and cycling modes
  • 12 POI categories: pharmacies, hospitals, water, fuel, food, ATMs, shelters, transport
  • On-device AI assistant (Apple Intelligence) — ask anything, no servers, no leaks
  • Auto-downloads your region on first launch so you're prepared before you need it

PRIVACY FIRST

  • End-to-end encryption with the Double Ratchet (Signal Protocol)
  • AES-256-GCM authenticated encryption on every message
  • No phone number required — your identity is your cryptographic key
  • No email, no account, no central server can ever see who you talk to
  • Zero metadata collection — we don't even know you exist

ON-DEVICE AI

  • Full conversational AI powered by Apple Intelligence
  • 100% on-device — no requests leave your phone
  • Multi-turn memory, contextual answers, suggestion chips
  • Available on iPhone 15 Pro and newer (iOS 26+)

ENCRYPTED VOICE & VIDEO CALLS

  • Voice and video calls with FaceTime-grade quality (AAC-ELD)
  • End-to-end encrypted with AES-256-GCM
  • Forward Error Correction for clean audio over weak links
  • Peer-to-peer when possible, relayed when not

COVERT COMMUNICATION

  • 6 steganographic channels to bypass censorship
  • Image steganography (LSB embedding)
  • Text steganography (zero-width, homoglyphs)
  • Web mimicry, DNS tunneling, domain fronting
  • Automatic channel selection based on network conditions

MORE

  • Group chats with admin controls
  • Disappearing messages with custom timers
  • Voice effects to mask identity
  • Bot platform (Telegram-style)
  • 16 languages, dark mode
  • Fully open source on GitHub — audit it yourself

OSHI is built for hikers, journalists, activists, travelers, preppers, and anyone who believes private communication is a right, not a feature. Download it now — and the next time the signal drops, the network goes down, or the borders close, you'll already be ready.
