Proton has unveiled Lumo 2.0, a significant upgrade to its privacy-centric AI assistant, introducing features like image generation, enhanced web search, and a memory function.
Originally launched in 2025, Lumo was designed to offer a secure alternative to mainstream AI chatbots by ensuring user data remains private. The latest version builds upon this foundation with a new architecture that supports two operational modes: Fast, which emphasizes speed, and Thinking, optimized for complex, multi-step reasoning. This enhancement results in response times up to 76% faster than the previous iteration.
A notable addition in Lumo 2.0 is its multimodal capability, allowing users to generate images from prompts, analyze uploaded images, and edit existing visuals within the same conversation. This feature broadens Lumo’s utility beyond text-based interactions.
The update also strengthens Lumo’s web search functionality, providing more accurate and comprehensive results. Additionally, the new Memory feature enables the assistant to learn user preferences and context, facilitating more personalized and context-aware responses. The context window has been expanded to accommodate this improved functionality.
Another innovative feature is Custom Lumos, which allows users to create specialized assistants tailored to specific tasks, such as research or project management, enhancing productivity and user experience.
Lumo remains free to use at Lumo.proton.me without requiring a Proton account. However, Proton account holders can benefit from zero-access encrypted chat history synchronization across devices. Mobile applications are available for both iPhone and Android platforms.
For users seeking advanced capabilities, Proton offers Lumo Plus at $12.99 per month, providing unlimited chats, advanced image generation, and priority access to faster models. Additionally, Lumo Professional is available for teams at $14.99 per user per month, offering secure collaboration features, with current discounts available for both plans.
Proton’s commitment to privacy and user control is evident in Lumo 2.0’s design, addressing growing concerns about data security in AI applications. As AI assistants become more integrated into daily tasks, Proton’s approach offers a compelling alternative for users prioritizing privacy without sacrificing functionality.
