Superhuman

Superhuman is an email polishing tool. Superhuman bundles three products: Go, an AI agent that works inside other apps and tabs, a fast email client with auto drafts and scheduling, and collaborative AI documents. The emphasis is on reducing tab switching and inbox time for individuals and teams, with shared agents and enterprise deployment as the upsell.

Superhuman is a productivity suite built around three products: Go, an AI agent that runs inside the apps and browser tabs you already use; Mail, an email client designed for speed; and Docs, a shared workspace where teams and AI work on the same surface. The company positions the trio as one toolkit for the workday rather than three separate tools, and each piece is sold and adopted on its own. Go is the center of the current pitch. Type a request and suggestions appear inline in whatever app is open, so the agent follows you instead of asking you to switch tabs. It covers preparation, writing and editing, email automation and agent building. Concrete examples on the homepage include a Daily Briefs view that pulls deadlines, commitments and meetings into one place, scheduling that finds a time and drafts an invite for your approval, and custom agents that gather emails, notes and docs ahead of a meeting or convert meeting notes into recaps with follow-ups assigned to owners. A no-code builder lets people describe an agent in chat or step through a visual builder, then share it with teammates or publish it to a company directory. Around 100 prebuilt agents from Superhuman and partners are available as starting points. The productivity work is reinforced by a set of writing and inbox utilities: Grammarly tuning, an Email Assistant that auto-drafts replies and clears noise, Auto Labels for priority filing, Auto Archive for marketing and cold pitches, Auto Drafts written from inbox and calendar context, a Humanizer for making AI text sound natural, a Knowledge Checker that verifies claims against company data, and an AI Detector that scores how much text resembles AI output. Mail adds booking links and a Split Inbox that surfaces important messages. The audience is knowledge workers, teams and enterprises that live in email and want AI assistance without juggling separate chat windows. Buyers comparing it to standalone email clients or single-purpose writing assistants should note that the value depends on adopting the wider suite.
