Proton launched an AI assistant called Lumo that puts privacy front and center.
The chatbot drops all conversation logs, uses end-to-end encryption for chats, and offers a “ghost mode” that deletes conversations when you close the window.
You can use Lumo through a web client, or on Android and iOS apps. It doesn’t require an account. Upload files and ask questions or link it to Proton Drive to access cloud files. It taps the web for info but may not deliver the freshest search results. 
Proton builds Lumo on open-source models and commits to no user data for training. It applies zero-access encryption so stored chats are only readable on your device.
The company is clear about its European roots as an edge on privacy compared to U.S. or Chinese AI companies.
Proton stated:
“Lumo is based upon open-source language models and operates from Proton’s European datacenters. This gives you much greater transparency into the way Lumo works than any other major AI assistant. Unlike Apple Intelligence and others, Lumo is not a partnership with OpenAI or other American or Chinese AI companies, and your queries are never sent to any third parties.”
This isn’t Proton’s first AI tool drop. It added an AI writing assistant for Proton Mail last year that runs locally on user devices.
