Superhuman is a premium AI-powered email management software built for professionals who live inside their inbox. The platform works as a layer on top of Gmail and Outlook, replacing the default interface with a lightning-fast, keyboard-first experience designed around the 100-millisecond rule every single action happens almost instantly. Founded in 2015 by Rahul Vohra in San Francisco and backed by $108 million from Andreessen Horowitz and Tiger Global, Superhuman email has become the go-to client for executives, founders, and sales teams who process hundreds of messages daily.
The core experience revolves around over 100 keyboard shortcuts that eliminate mouse clicks entirely. You press C to compose, E to archive, H to snooze, and J/K to navigate once the muscle memory sets in, triaging an overflowing inbox takes minutes instead of hours. Split Inbox lets you separate messages into custom tabs like VIP contacts, newsletters, and calendar notifications. The Command Palette accessed through Cmd/Ctrl+K gives instant access to any feature by typing, so you never need to hunt through menus. The superhuman app is available as a superhuman desktop app for Mac and Windows plus mobile apps for iOS and Android.
Superhuman AI is where the platform has evolved most aggressively. Auto Drafts automatically writes follow-up emails in your voice without any prompting the draft appears ready to edit and send. Auto Labels classify every incoming message into categories like response needed, waiting on, meetings, and cold pitches. Auto Archive sweeps marketing and cold emails out of your primary view automatically. The Write with AI feature learns your writing style from sent emails and generates content that maintains your personal tone, while Instant Reply drafts responses to incoming messages so you can send with a single click.
In late 2025, Superhuman acquired by Grammarly marked a significant shift the two brands now operate as a combined productivity suite while Superhuman continues independently under its original leadership. The Grammarly Superhuman integration brings writing assistance directly into the email workflow. Superhuman Go the platform's AI assistant handles scheduling, research, and task management alongside email. For teams, shared conversations, team comments, and CRM integrations with HubSpot and Salesforce make Superhuman a collaborative workspace rather than just a personal inbox tool.
