Score: 8.3/10 (Innovation: 8, Technical: 9, Documentation: 10, Utility: 8)

uOS is a browser-based end-to-end encrypted workspace suite (chat, mail, docs, video, etc.) that uses post-quantum cryptography (ML-KEM, ML-DSA) to ensure the server operator cannot read user content. It extends a unified encryption model across all applications and offers organisation features like key escrow and compliance controls without compromising operator blindness.

Target audience: privacy-conscious organisations, security engineers, compliance officers, and teams requiring post-quantum secure collaboration
