If you want email to be fast on a Mac, three apps come up again and again: Superhuman, the premium keyboard-first client; Mimestream, the native Gmail app; and Dusk, the native app with on-device AI. Here's how they compare, and which one suits you.
The short version
- Superhuman if you need Outlook, Windows or team features, and don't mind $300 a year and cloud AI.
- Mimestream if you use only Gmail and want it exactly as Google designed it, with no AI.
- Dusk if you want Superhuman-style speed and AI on your Mac, for $49 once, with Gmail and iCloud.

Speed
All three are fast. Superhuman built its brand on speed, with every action designed for the keyboard. Mimestream is a native Swift app, so it feels quick and at home on a Mac. Dusk is also native Swift, about a 12 MB download, opens in under half a second, and applies every action to your inbox instantly before syncing in the background.
The real difference is how much of your email you have to read. Superhuman and Dusk both sort your inbox so the important mail rises to the top. Mimestream shows Gmail's own categories and leaves the sorting to you.
AI
- Superhuman has AI summaries and reply writing, powered by cloud models. Your email is processed on its servers.
- Mimestream has no AI features.
- Dusk sorts every email into Important, Needs reply, Waiting, Newsletters or Screened, writes a one-line summary under each, digests long threads, and suggests replies in your style. All of it runs on Apple's on-device model, so your mail never leaves your Mac.
Privacy
Mimestream and Dusk both talk to Gmail directly from your Mac. Dusk adds AI without changing that, because the model is on your Mac. Superhuman's AI requires sending your email to its servers. If your inbox holds anything confidential, that's worth weighing.
Price
This is where they differ most. Over three years, Superhuman costs up to $1,080 per person, Mimestream $150, and Dusk $49.
