Superhuman

Superhuman built its reputation as the fastest, most keyboard-centric email client on the market, and that core promise still holds up — power users routinely report meaningful time savings once they adapt to its shortcut-heavy workflow. Its expansion into a broader AI productivity suite (Go, Docs, Calendar) is ambitious and mostly well-executed, with AI assistance that feels genuinely proactive rather than bolted-on, but it also means the product is no longer the narrow, focused tool it once was. The steep price point remains the biggest sticking point: it's a tool built for professionals whose time is worth the premium, not for casual email users who can get 80% of the benefit from free alternatives now shipping their own AI features. For teams and individuals who live in their inbox and want a status-symbol-fast workflow, it's still one of the best in class.
