BoxBee is an AI email client for macOS, Windows, iOS and iPadOS, built in Luxembourg by TTA Technologies. It is a mail client, not a mail provider: users keep the IMAP/SMTP mailbox they have. Arriving mail is grouped by kind and urgency. The app drafts replies in the language of the message and presents a daily brief of open items, plus a mail-linked calendar, archives and dossiers, search by meaning, BeeCrypted messages between users, and an autopilot that can classify, file and quarantine marketing. The AI runs on Mistral in the EU. Mail contents and passwords are not stored on BoxBee servers. Not Boxbe (email screening) and not the storage company bought by Iron Mountain.
