Both are proper Mac apps for Gmail. Mimestream is a faithful, polished Gmail client with no AI. Dusk sorts and sums up your mail with the AI on your Mac, adds iCloud, and you pay for it once.
The short answerIf you want Gmail on the Mac exactly as Gmail works, with labels, filters and aliases, and no AI, Mimestream is excellent. If you'd rather your inbox arrived already sorted and summarised, want iCloud in the same inbox, or prefer to pay once, choose Dusk.

Why people choose Dusk over Mimestream
- Your inbox is sorted for you. Every email lands in Important, Needs reply, Waiting, Newsletters or Screened, with a one-line summary.
- Replies written for you. Press Tab for three suggested replies in your own style, or ⌘J to say what to write.
- iCloud too. Dusk puts Gmail, Google Workspace and iCloud in one inbox. Mimestream is Google only.
- Pay once. $49, then it's yours. Mimestream is $49.99 every year.
Private and quick by design

- 0.9 s
- to sort and sum up an email
- No Dusk server between you and your mail. Dusk talks to Google and iCloud directly from your Mac, and there's no analytics.
- AI with no cloud fallback. Sorting, summaries and drafts use only Apple's on-device model, and still work offline.
- Tracking blocked. Emails are shown with scripts off and every remote image and tracker blocked, so senders can't see when you open them.
- Phishing set aside. A stranger's urgent email linking to a different site goes to Screened, not your inbox.
- Safe sending. Undo send, reply all only when you choose it, and a failed send is never resent blindly.
- Your keys stay yours. Sign-ins are stored in the macOS Keychain, and your licence is checked on your Mac.
Measured on a pre-release build on a MacBook Pro with M3 Max: zipped universal download, warm launch, idle memory with example mail, and triage of one email. Older Macs are slower.
