Encryption

Proton has upgraded its privacy-focused AI assistant, Lumo, with Lumo 1.1 offering faster, smarter responses while maintaining user confidentiality. The upgrade boasts significant improvements in reasoning, contextual understanding, and code generation. Unlike competitors, Lumo prioritizes privacy through end-to-end encryption, non-storage of conversations, and open-source mobile app code, allowing for community scrutiny. While full usage requires a Lumo Plus subscription, Proton bets on users valuing privacy enough to pay for it, challenging the conventional trade-off between AI power and data security.

Elon Musk launched XChat, an encrypted messaging platform for X (formerly Twitter), featuring end-to-end encryption, self-destructing messages, file sharing, and audio/video calls without phone numbers. Built with Rust and “bitcoin-like” encryption, it aims to become an all-encompassing “everything app” like WeChat. Currently, XChat is available to select paying users and secured with a passcode, representing a major step in Musk’s broader strategy for the platform.
