Group video calls
Multi-party video — inside the same encrypted MLS group.
When cell towers go silent — we keep talking
Two phones nearby — messages flow with no Internet. A small group on the same Wi-Fi stays in touch. And a neighbour with a connection becomes a courier, passing the encrypted envelope along.
- Bluetooth + Wi-Fi Direct — direct peer-to-peer
- Local Wi-Fi — small-group sync without the cloud
- Courier relay — ciphertext through a trusted neighbour
Your Telegram opens here
TDLib client bridge: SVOI connects to Telegram on your behalf and shows your channels and chats in a single surface. No key handover — we're just a client, not a middleman.
- Read your channels and chats without leaving SVOI
- Keeps working when Telegram throttles
- Migrate history into an encrypted local archive
Calls get through where others go silent
Group audio on LiveKit SFU. The primary path is TURN over TLS-443 — the same port as regular web traffic. If UDP is fine, we go direct. If not, the handshake is longer, but the call connects.
- LiveKit SFU — low latency for groups
- TLS-443 as the primary path, not a fallback
- Works on networks with deep-packet inspection
An archive that doesn't forget
Free keeps old media on your own devices — encrypted, for free. Premium adds the cloud archive: open a chat on a new laptop and the whole archive is already there.
- Free: local archive on your own devices
- Premium: encrypted cloud, key stays with you
- Works even when your other devices are offline
