Proton has unveiled Lumo, an innovative privacy-focused AI assistant that revolutionizes how we interact with technology by prioritizing user confidentiality. Operating from secure European data centers, Lumo distinguishes itself from traditional AI tools with its commitment to zero-access encryption and the absence of server-side logs, ensuring that conversations remain completely private.

One of Lumo's standout features is its ghost mode, which allows users to engage in temporary chats that disappear without leaving any trace. This feature, among others, highlights Proton's dedication to safeguarding user privacy and exceeding industry standards. Notably, Lumo requires no account for usage, granting ease of access across various platforms, including web, Android, and iOS.

Lumo is built on open-source models and has integrated capabilities for file uploads via Proton Drive. This seamless connection enhances user experience by allowing encrypted file access and sharing while maintaining end-to-end security. Users can leverage Lumo to summarize documents, generate code, write emails, and perform web searches through privacy-friendly engines.

While Lumo offers free access with limited features, users can opt for a $12.99 monthly subscription to unlock unlimited capabilities. By not utilizing user data for training and ensuring the protection of data from third-party access, Lumo sets a new standard in privacy-first digital assistance, ensuring that sensitive data remains solely under user control.
