Proton Updates Lumo AI With Image Tools and Persistent Memory

*Proton rebuilt its privacy-focused chatbot on a new architecture that adds image generation, user memory, and private web search while keeping its no-logs stance.*

Proton released Lumo 2.0 today, the largest update to its AI assistant since the service launched last year. The Swiss company rebuilt the system on fresh infrastructure that supports Fast and Thinking modes and delivers responses up to 76 percent quicker on routine queries.

The new version introduces multimodal features. Users can now generate images and upload photos for analysis. Memory lets the assistant retain context across conversations. A private web search option routes queries without logging or sharing data, consistent with Proton’s zero-access encryption model.

Lumo 2.0 also carries forward the two operating modes introduced in the update. Fast mode favors speed for simple tasks. Thinking mode handles multi-step reasoning. Both run under the same privacy constraints that prohibit data sharing with third parties.

Reactions

No outside commentary appears in the initial announcements. Proton positions the changes as direct responses to user requests for capability without compromising its core encryption guarantees.

Why it matters

Users who already trust Proton Mail and VPN now have an on-brand option for an AI assistant that stores less about them than mainstream alternatives. The 76 percent speed gain and image tools narrow the gap with larger providers, yet the architecture still routes everything through Proton’s own encrypted stack. For developers and privacy-conscious teams evaluating AI copilots, the release supplies a concrete test case: whether the added features justify another subscription or whether the remaining capability gap still outweighs the privacy margin.
