Superhuman AI
Imagine an inbox that automatically summarizes every email, drafts your replies, and powers your writing.
Superhuman AI helps you take action on your inbox faster than ever before! 🚀
Activating Superhuman AI
When you first onboard Superhuman, you have the option to activate Superhuman AI. If you haven’t already activated, you can do so manually in each of your accounts.
To activate Superhuman AI manually, you can hit Cmd+K (Mac) or Ctrl+K (Windows) → Activate Superhuman AI.
Write with AI
Once Superhuman AI is activated, you can hit Cmd+J or Ctrl+J in an open draft to activate AI Compose.
Drafting Mode
You can draft a message by typing your prompt and hitting Enter. 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!
Auto Summarize on Desktop and Mobile
Auto Summarize allows you to gather context of a conversation within seconds!
To activate Auto Summarize, hit i within an open conversation.
You will find a 1-line summary underneath the subject line. For a more detailed summary, just hit i to expand.
Instant Reply on Desktop and Mobile
Wake up to an inbox where emails already have a draft reply with Instant Reply.
We show three draft replies at the bottom of the latest message. You can hit Tab to cycle and preview each response.
To insert the reply, hit Enter (Reply All), R (Reply) or F (Forward).
Ask AI (beta)
Let Superhuman AI do the work for you! With Ask AI, use natural language to ask a question and get a clear, concise, personalized answer in return with direct citations to relevant emails — it's blazingly fast⚡

FAQ 💡
Who is Superhuman working with to provide AI features and what model are you using?
Our AI features are powered by mixture of models from OpenAI.
Will my emails be stored?
With Ask AI enabled, Superhuman stores your emails through a trusted SOC 2 compliant third-party vendor. Your data is encrypted both in transit and at rest.
OpenAI does not store any data. We uphold a formal Zero Day Retention agreement with OpenAI, which is line with their API policies.
Will the queries I send and responses I receive back be stored?
We do not store the queries used for Write with AI, Instant Reply, and Auto Summarize.
We do not store responses for Write with AI. For Instant Reply and Auto Summarize, we store the responses for 90 days so that they are available for you if you open the email again.
The queries used and responses received for Ask AI are stored during the beta to help improve quality and allow for debugging.
We do not read responses or your email content unless you explicitly give us consent while submitting feedback.
Will anyone train on my data?
Neither Superhuman nor any vendor (including OpenAI) trains on your data.
Can I request to have my data deleted?
Yes. If you would like your data deleted, please reach out to hello@superhuman.com.
Can I opt-out of Ask AI and still use other Superhuman AI features?
Our Superhuman AI features are designed to work together. There isn't a way to pick-and-choose which ones are enabled and which ones aren't.
Why doesn’t "Rewrite in my own voice" sound like me?
When you first enable Superhuman AI, we run an analysis against a sample of your latest emails to get a sense of your tone and writing style. If this doesn't feel quite right, please let us know by shooting an email to hello@superhuman.com.
Why am I not seeing a summary on some of my conversations?
Certain types of emails do not receive an automatic summary with Auto Summarize. Those emails include:
- Emails not in your inbox (social/etc)
- Emails with a Smart Link (such as View Pull Request, Unsubscribe)
- Very long emails (the limit is approximately >20,000 words or 80 pages of text)
- Emails from SendGrid (these often are transactional emails like password resets).
Any email is eligible for a manual summary by just hitting M!
