Proton Mail vs a Secure AI Email Client: PGP and Unified Inbox

Proton Mail focuses on providing a privacy-first hosted mailbox with its own web and mobile apps. It is ideal for users who want a fully secure, provider-managed email account.

Canary Mail, on the other hand, is a secure AI-powered email client that connects to your existing providers - including Proton, Gmail, Outlook, iCloud, and any IMAP account - without requiring you to change your email address. It adds AI capabilities, a unified inbox, and PGP encryption, giving you a centralized, productive, and secure email experience.
