Introduction
Superhuman is a premium AI-powered email client designed for high-performing professionals and teams who spend hours in their inbox.

Its “Superhuman AI” features include instant thread summarization, auto-drafting based on brief notes, and “Instant Reply” options that allow users to respond to emails in seconds. Its mission is to make users feel “superhuman” by turning email from a chore into a fast, fluid, and even enjoyable workflow.

Review
Superhuman AIis known for its unparalleled user experience and speed. Its primary strength is the seamless integration of AI into a “keyboard-shortcut-first” workflow, which allows users to process hundreds of emails without ever touching a mouse.
The Auto-Summarize feature is particularly effective at distilling long corporate threads into actionable points. While the premium price tag ($30/mo) makes it a significant investment compared to free clients, the time saved (often cited as 3+ hours per week) and the psychological relief of a clean inbox provide an immense ROI for executives, founders, and power users.
Features

You type a few bullet points (e.g., "Thanks, but too expensive"), and the AI drafts a polite, professionally worded email in your specific voice.

Getting started with: step by step guide
The Superhuman workflow is designed to move through the inbox in a single “sweep” using keyboard commands.
Step 1: The "Sweep"
The user opens the app and sees their Split Inbox. They use J and K to move through messages.
Step 2: AI Summary
For long threads, the user reads the Instant Summary at the top to understand the status without scrolling.
Step 3 : Instant Reply
The user hits R and selects an AI-suggested “Instant Reply” (e.g., “Interested”) to let the AI draft a full response.
Step 4: Write with AI
For custom replies, the user hits Cmd+J, types “Accept meeting for Friday 2pm,” and the AI generates the full invite.
Step 5: Snippet/Send
The user hits Tab to accept the draft, then Cmd+Enter to send.
Step 6: Archive
The user hits E to archive the message and immediately moves to the next one, repeating until the “Inbox Zero” screen appears.
