Until I logged-in to Proton uservoice.com, I didn't know that Lumo exists. I do not recall getting an email notification. I got a notification, e.g., for Proton Authenticator. Anyway, I'm researching Lumo now, as I definitely can see myself using a Proton chatbot vs. other (data-collecting) offerings from those evil IT megacompanies. Currently, I have DuckDuckGo's DuckAssist set to offer answers as frequently as possible.

I really see traditional web search being replaced by AI-based search entirely. Perhaps AI-based search is the answer to finally being FREED from all the marketing results when you really want information rather than product/company/shopping results. (Good riddance Google, Bing, etc.)
