Gusk AI

Keep what matters. Sweep the rest.

Gusk AI turns an overflowing inbox into a few quick decisions.

Instead of reading thousands of emails one by one, Gusk groups them — by sender, by domain, by subject — and shows you where your mail really comes from.

SWEEP IN BULK • See every sender and domain ranked by volume, size and unread count • Archive, move to Trash, mark read or unsubscribe from a whole group in one tap • Undo any action • Empty Spam and Trash in one go

UNDERSTAND YOUR MAIL • Subjects, senders and domains in a clean table or grid • Activity heat map shows when mail arrives • Smart views: bookings, packages, bills, to-dos and bulk mail • Suspicious-sender warnings and one-tap blocking

ON-DEVICE INTELLIGENCE • An AI insight for every sender: what they send, how often, and whether it's worth keeping • Ask questions about your mail and get summaries with Apple Intelligence • Everything runs on your device — your email is never sent to an AI service

A COMPLETE MAIL APP • Add several accounts and see them together in one unified inbox • Read, reply and forward with rich text formatting • Attachments shown with their file type • Signatures with fonts and colours, synced across your devices through your own mailbox • Works on iPhone and iPad (Gusk AI for Mac is available separately)

PRIVATE BY DESIGN • Connects directly from your device to your mail provider over encrypted TLS • Your app password stays in your device's Keychain • No accounts, no servers, no tracking, no ads — the developer never sees your mail

WORKS WITH Gmail, iCloud Mail, Yahoo Mail, Zoho Mail and other IMAP services, using an app password from your provider. Gusk walks you through creating one.
