Curo vs Proton Mail

A Proton Mail Alternative With Encryption Plus an AI Chief of Staff

Proton Mail is a gold standard for private, end-to-end encrypted email, and that's exactly the bar Curo holds itself to. The difference is what happens after your mail is secure: Proton leaves the triage and replying to you, while Curo adds an AI chief of staff that prioritizes your inbox and drafts responses in your voice. You keep the privacy and gain the help.

Questions

Is Curo as private as Proton Mail?
Curo is end-to-end encrypted and private by design, so your mail stays protected. The added AI works on your behalf without giving up that encryption.
Can Curo manage my non-Proton accounts too?
Yes. Curo unifies all your mailboxes across providers into one inbox, which goes beyond Proton's single-ecosystem focus.
Does the AI mean my email is less secure?
No. Curo is built encryption-first; the AI triage and drafting operate within a privacy-by-design architecture, not by exposing your inbox.
Do I have to leave Proton to try Curo?
No. You can connect your existing accounts to Curo and keep using them, with Curo handling triage and drafting on top.
