Proton — famous for its privacy products — built Lumo because they believe "privacy shouldn't be sacrificed for AI convenience".
Unlike other AI assistants that store and analyze your conversations, Lumo uses zero-access encryption — even Proton can't see your chats.
What makes Lumo unique is combining the power of modern AI with genuine privacy protection, backed by a nonprofit foundation, offering the first AI assistant where 'confidential' actually means confidential.
Since zero-access encryption prevents the assistant from seeing past conversations, how do you handle features like personalization or learning from user interactions?

@vouchy I presume it means they eschew personalization.
This is promising. Lumo feels like a strong alternative to Duck AI as it also anonymizes interactions with third-party AI models. But Lumo with zero-access encryption, it’s doubling down on privacy so they have an edge here. Good to know about this one!
And congrats to Proton team for the launch. Great work done here!
This is why I pay a proton subscription. I wish they had something like Nebo for handwriting notes and paired it with this AI assistant.
The challenge of giving the model access to my data but not anyone else is real, but I'm glad Proton is taking a shot at it. I've been using the paid version and am happy that my conversation history remains accessible to me. Does the model keep access to it as well? I can't quite tell yet.
