Superhuman focuses on a lightning-fast, keyboard-driven interface with a minimalist design, while Shortwave emphasizes AI-powered features like natural language search and email drafting. Both target professionals who handle high email volumes, but they differ significantly in approach, pricing, and integrations.

Key Features Comparison
