Proton Mail is, where all the important information is, that I need to run my business. Ever so often it happens, that I am looking for a specific piece of information that I know, is buried in some email somewhere. And with the UI and the search that we have today it is very annoying to find anything.

It would be very cool, when some kind of personal AI assistant would help me with that. For example i could ask: “what was the price I landed on with client x on project y” and it gives me the answer. Like mem.ai, but built in to Proton Mail.

I know this is hard to achieve upholding your high privacy standards, but I think you are the experts on that and maybe there is a way.
I also think this will be the future of search everywhere and not having it will very soon be a mayor disadvantage.
