QT-AI

Private by Default · Local-First · Peer-to-Peer Collaboration

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.

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
