Superhuman for humans
Superhuman is a fast, keyboard-first email client on top of Gmail and Microsoft 365. Split inbox, reminders, and snippets are the product. There is no public agent API to drive Superhuman itself — agents should hit Gmail or Graph instead. We include it because it is globally famous among operators, and because a high human score with a low agent score is the point of Twin Pages. Twin Score on this directory is 88 for humans and 40 for agents, using the public rubric (interface, onboarding, human docs, collaboration, support, pricing fairness, accessibility, reliability versus API quality, MCP or tool surface, CLI, structured docs, machine auth, quotas, determinism, and skill packaging). Superhuman is sold by Superhuman, founded 2014, headquartered in San Francisco, USA. Pricing in public materials: Premium per-seat subscription, historically among the most expensive mail clients. Machine capabilities we record: API none, MCP none, CLI none, docs basic, auth Google/Microsoft OAuth for the mailbox. This page is editorial, not a star rating scraped from users.
