CORTEX
"Can't stop the signal."
A privacy-first, federated communication platform. End-to-end encrypted messaging for those who value their freedom in the digital frontier.
// FEATURES
End-to-End Encryption
Zero-knowledge encryption using ECDH P-384 and AES-256-GCM. Your messages are yours alone. The server never sees plaintext.
Federation
Connect Cortex instances across the Verse. Cover traffic and message padding resist traffic analysis between allied ports.
Threaded Waves
Conversations that flow naturally. Focus on any thread, isolate reply chains, collapse long messages.
Voice & Video
Record voice and video messages. Real-time calls with screen sharing via LiveKit. Media server integration for Plex, Jellyfin, and Emby.
Privacy Hardened
Encrypted metadata, anonymized IPs, hidden waves with plausible deniability. Ghost Protocol means you can't prove who's in a wave.
Customizable
Create and share custom themes. Holiday effects. Outgoing webhooks to Discord, Slack, and Teams. Installable PWA with push notifications.
// TERMINOLOGY
Cortex uses terminology inspired by the frontier spirit of the Verse.
// THE BLACK KEEPS SECRETS
Cortex was built with privacy as its foundation, not an afterthought. Communication should be free from surveillance.
End-to-end encryption means even the server operator cannot read your messages. But we go further — metadata is protected too.
Encrypted Metadata
Emails, wave participation, crew membership, push subscriptions, and contact lists are all encrypted at rest. A database dump reveals nothing.
Anonymized Footprint
IPs anonymized to /24 subnet. User-agents truncated. Timestamps rounded. Activity logs auto-deleted after 30 days.
Ghost Protocol
PIN-protected hidden waves with cryptographic participation deniability. Nobody can prove you were in a wave without your key.
Running Dark
Federation cover traffic, message padding, and queue jitter make real messages indistinguishable from decoys.
