Superhuman’s new AI suite fact-checks your life | usagoldmines.com

You’ve probably heard of Grammarly, the AI spelling and grammar checker. But with a rebrand, a consolidation, and a new AI agent, Grammarly now fact-checks your business communications using what it knows about current context.

It’s difficult to describe this iteration of Grammarly, now renamed Superhuman, and its suite. (Fortunately, the company put together a short GIF describing how it works, which is embedded below.)

Essentially, the Superhuman suite and its Superhuman Go app run various agents against your own (or AI-generated) copy, correcting any mistakes you inadvertently made about a variety of topics.

Consider this example: you’re emailing a coworker, Erica, about a sales call to be held tomorrow at noon. If you misspelled “Erica,” you’d expect that it would be underlined, indicating an error.

In this case, if the meeting was moved–and if Superhuman was connected to your Google Calendar–it would underline the meeting time and suggest you rewrite it with the new time instead. If the subject of the call changed, this too would be highlighted, as long as the CRM service was looped in. The Superhuman suite is fact-checking your email, but it functions more like a spellchecker.

The Superhuman suite includes Grammarly, the Superhuman Mail program, the Coda all-in-one workspace, and the Superhuman Go AI program, which connects all of them together. It certainly isn’t cheap; Superhuman is charging $25 per user per month for a Starter subscription, with a more advanced Business sub that pulls in some additional features. However, the Go features will be free at no additional cost through Feb. 1, 2026, and the technology will be available to Grammarly and Superhuman suite users on Chrome and Microsoft Edge. Windows and Mac users will add the new Go capabilities “soon,” Grammarly said.

The Superhuman suite allows users to move between the apps themselves, such as the Superhuman Mail interface, the Grammarly AI writing tool, and the Coda workspace. But the secret sauce will be the agents themselves.

Superhuman is launching an agent store where users can download specific agents. These include Google Workspace tools, Microsoft Outlook, Atlassian Jira, and Atlassian Confluence, available today. Some partner agents are designed for specific tasks, like Fireflies, Common Room, Latimer, Parallel, Radical Candor, and Quizlet, which are also available today. The premise is familiar: connect more agents to the applications, give them access to more of your data and, supposedly, your productivity will improve.

Grammarly/Superhuman said that “nothing changes” in terms of the products and their privacy protections. “The company does not sell or monetize user content, ensures users are in control of their data and own what they write, and does not allow its third-party service providers to train their models on user content,” the company said.
