The story
Superhuman is a unified brand with a long history behind it. Grammarly was founded in 2009, and Coda, now Superhuman Docs, and Superhuman Mail followed in 2014. Grammarly bought Coda and Superhuman Mail in 2025 and launched Superhuman as the name for the whole suite.
The product
Superhuman Mail is a fast, keyboard-driven email app for Gmail and Outlook. AI sorts and labels incoming mail, drafts replies in your voice, sets reminders and can archive clutter automatically. Split inbox, snippets, send later and scheduling tools sit alongside it, and it runs on desktop, the web and mobile.
The suite
Grammarly handles writing help across your apps, Docs is the shared workspace for teams and AI, and Go is an assistant that offers help inside the tools you already use. It also has custom agents for things like meeting prep, meeting recaps and checking claims, and a library of ready-made agents you can share with teammates. Grammarly's tools can also help you sound natural when text has been written with AI.
Pricing
Superhuman Mail is a paid product with no free Mail plan, and plans are priced per member. Billing is in US dollars with annual billing cheaper than monthly, so UK buyers should expect a currency conversion and to check how tax is applied at checkout. Higher tiers add more advanced AI, and larger teams talk to sales.
Who it suits
It is built for heavy email users, such as founders, sales and customer-facing teams, who want to clear their inbox quickly. Teams get shared conversations, comments and drafts, plus coaching on the plans that include it. If you only want writing help, Grammarly on its own may be the lighter choice.
Cancelling
You can cancel at any time and keep access until the end of the billing period. Superhuman's terms say payments are non-refundable where the law allows.
