Proton launches Lumo for Business, a privacy-first AI assistant built for companies handling sensitive data, offering secure workflows, zero-access encryption, and full open-source transparency.

Proton has released Lumo 1.2, introducing dark mode, customizable writing styles, Proton Drive integration, and a new Lumo Plus plan — all secured with zero-access encryption for maximum privacy.

Proton Lumo is a new AI assistant focused on privacy, with no server-side logs and open-source LLMs. Is it the secure AI you've been waiting for—or just another assistant in disguise?
