Make Gmail work like Superhuman
CMDK (formerly Simplehuman) is a browser extension that adds command bar and advanced keyboard shortcuts to Gmail. Snooze with natural language, navigate to folders, one click unsubscribe.
CMDK's read receipts feature quietly tracks when sent emails are opened and reopened, showing who engaged with messages. This eliminates guesswork about follow-up timing, particularly valuable for sales and vendor communication.
CMDK provides 80+ keyboard shortcuts, a command bar (Cmd+K/Ctrl+K), and one-click actions (archive, delete, mark read) that eliminate mouse usage. Users triage email at speed of thought without touching the mouse, achieving faster inbox processing than native Gmail.
CMDK displays keyboard shortcut suggestions whenever users click the mouse, gradually training them to use faster keyboard-based workflows. This scaffolded learning approach helps users transition from mouse-dependent to keyboard-efficient email management at their own pace.
CMDK delivers command bar, read receipts, advanced shortcuts, and smart actions at $9/month or $169 lifetime, positioning as a direct Superhuman alternative. Users save $300-480 annually while retaining native Gmail UI and compatibility with existing extensions.
CMDK Tabs feature creates custom inbox splits (work, personal, projects) accessible via Tab key cycling. Users can also block spammers in one click and use natural language reminders ('remind me next Monday 9am') to resurface emails when needed, enabling inbox zero without manual sorting.
