Proton Launches Privacy-Centric AI Assistant, Lumo - Proton has launched Lumo, a privacy-first AI assistant that prioritizes user data protection. It includes end-to-end and zero-access encryption, and offers ghost mode for ephemeral chats. Lumo is accessible via web and mobile apps without requiring an account, allowing for integration with Proton Drive for file access.
Using open-source models and based in Europe, Lumo ensures data privacy and transparency by not using user data for training. This development follows Proton's prior AI integration into its Mail product, reinforcing its commitment to secure user privacy in AI tools.
