On Tuesday, Proton introduced Lumo 2.0, the second iteration of its privacy‑first AI assistant. The company says Lumo 2.0 uses new reasoning models that respond faster and handle complex, multi‑step queries better than the previous version.
Proton positions Lumo as a chatbot-style assistant that offers “intelligence without surveillance” by storing data under Swiss privacy laws with zero-access encryption, meaning staff can’t read user conversations.
The new Lumo allows users to upload images, such as photos and charts, and then ask questions or request edits. The assistant can also generate new images and turn rough drawings into polished visuals. In terms of web integration, Lumo searches the internet for live information and provides sources for each response, helping the user fact-check outputs before potentially falling for hallucinations.
The update increases Lumo’s context window and adds user-controlled long-term memory. Lumo can now remember preferences, work style, ongoing projects, and more. Proton says it keeps logs off and does not train models on user data.
Lumo’s free tier gives core private AI access, while Lumo Plus adds unlimited chats, projects, and image generation. Lumo Professional and Lumo for Business are for teams and enterprises with admin controls.
