Swiss privacy company Proton launched Lumo 2.0 today, a major overhaul of its AI assistant that maintains the service's core promise of no logs, no data sharing, and zero-access encryption. The update introduces a rebuilt architecture with Fast and Thinking modes, delivering up to 76 percent faster response times than the previous version for everyday queries.

Lumo 2.0 adds multimodal capabilities including image generation, recognition, and editing within conversations. Users can now create visuals from prompts or sketches, analyze uploaded images, and modify existing graphics without leaving the chat interface. The platform also features significantly improved web search functionality and a Memory system that learns user preferences and maintains context with a window twice as large as before.

Custom Lumos enables purpose-built assistants tailored to specific tasks like research workflows. While Lumo remains free at Lumo.proton.me without requiring a Proton account, the Plus tier at $12.99 per month offers unlimited chats, Projects, and advanced image generation. A Professional plan for teams costs $14.99 per user monthly with secure collaboration features.

This positions Proton as a privacy-focused alternative to mainstream AI assistants that typically collect user data for training. The company's zero-access encryption approach differentiates Lumo in an increasingly crowded AI market while adding features that match or exceed competitors' offerings.
