Proton has their own AI bullshit:
At least it’s not rummaging around your email though.
And just so you know, it is not end-to-end encrypted like their email is when emailing another Proton user: https://lumo.proton.me/legal/privacy
The only way to have actually private AI is to run it on your own hardware.

Sorry if my aversion to advertising comes off as smarmy, im tired of seeing companies go from focusing on providing one good service like email and trying to become the next one corp fits all replacement for google. Instead of doing one thing extremely well it becomes a race to do as many things as they can and get people to replace one monolith with another.
