All of the advice I give depends on your preferred level of privacy. If I had to give you all of these services in 1 provider I'd suggest Infomaniak, a Swiss tech company. https://www.infomaniak.com/en/ksuite/kdrive VPN: Mullvad (it collects less data from the user, even) Email: not sure about this. I never used Proton Mail since it didn't work for me with IMAP protocols by design. Password Manager: Bitwarden or self-hosted Vaultwarden AI: I use DuckDuckGo's Duck.ai interface, although I'm not entirely sure if that measures up to the privacy standard you need.

Depends on what you need. Tuta for Mail is great. If you'd like to self host password managers, stuff like Keepass/Vaultwarden/Bitwarden. You can also choose to pay for Bitwarden if you'd prefer a managed infrastructure. The only AI I'm familiar with that has some level of self respect is Mistral with Le Chat. Not familiar with VPN/Cloud storage.
