Write with AI

Summarizing every email, drafting your replies, supercharging your writing, and searching your inbox, Superhuman AI helps you take charge of your inbox faster than ever before! 🚀

Activate Superhuman AI

When you sign in to a new account, activate Superhuman AI. Hit Cmd+K (Mac) or Ctrl+K (Windows) → Activate Superhuman AI.

Write with AI on Desktop

When drafting a message, hit Cmd+J or Ctrl+J to write with AI.

Drafting Mode

Type a prompt and hit Enter to have Superhuman AI draft a message. The more context and keywords you include, the more specific the drafted message will be.

You can accept the message to make small edits or make larger edits within Editing Mode.

Editing Mode

You can access Editing Mode in two ways:

  • Directly after a message has been crafted in Drafting Mode
  • Highlighting existing text and hitting Cmd+J or Ctrl+J

In Editing Mode, you can select a suggestion (Improve writing, Shorten, Lengthen, Simplify, etc.) for a quick change to the draft, or type in a more specific editing prompt for a larger change. You can even type 'translate to Spanish' to have the entire draft rewritten to Spanish or any other language!

Write with AI on Mobile

On iOS (coming soon for Android), you can use AI Compose by tapping on the ai icon above your keyboard.


⭐ Hot tip: Instead of writing your prompt, utilize Voice Dictation by tapping the Microphone icon at the bottom right corner of the keyboard!
