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.

How we chose

  • No required monthly or yearly fee
  • Works well on a Mac
  • What you give up for the price

We make Dusk, so we've put it where it fits the question and said plainly who each other app suits better.

Questions

Is there a Superhuman-style app without a subscription?
Dusk is keyboard-first with AI sorting and replies, for a one-time $49.
Dusk or eM Client?
Both cost about £49 once. eM Client covers more accounts and platforms and includes a calendar, and its AI is ChatGPT in the cloud at extra cost. Dusk is Mac only and keyboard-first, and its AI runs on your Mac and is included.
Will a one-time app keep getting updates?
Dusk 1 keeps working forever. A future major version may be a paid upgrade. eM Client and Mailbird also sell lifetime upgrade options.
