QT-AI

Private by Default · Local-First · Peer-to-Peer Collaboration I a world full of Hackers and Vulnerabilities -- QT-AI is a privacy-first, browser-based collaboration platform designed for teams that need secure, real-time communication without relying on centralized servers. All collaboration happens directly between peers, and your data always stays under your control.

QT-AI is built for confidential business discussions, research teams, and private collaboration, QT-AI focuses on speed, simplicity, and privacy by design.

✨ Core Principles

  • Private by Default – No central server stores chats, files, or history
  • Local-First Architecture – Your data lives in your browser
  • User-Controlled Collaboration – Nothing is shared unless you choose
  • Peer-to-Peer Networking – Direct connections using WebRTC
  • Zero-Backend Design – No database, no cloud storage, no tracking
