What is Superhuman?

Superhuman Mail is an email app with AI features such as Ask AI, Auto Labels, Auto Drafts, Instant Reply and Auto Summarize. The vendor's help pages list a Mac app or Chrome extension, iPhone/iPad and Android apps, and a 2024 blog post lists Mac, Windows and web with Gmail and Outlook accounts.

Who it's for

The Mail plans page lists per-member Starter and Business plans for teams of up to 25 seats, and Enterprise with unlimited seats for larger groups. Since the company's rename from Grammarly to Superhuman, Mail is also part of a suite with Grammarly, Docs and Go, which the suite page includes from its Business plan.

Pros & cons

Strengths

The Mail plans page lists Starter as covering email productivity, Superhuman AI, team collaboration, calendar and scheduling, unified admin and billing, and group productivity coaching.
Superhuman lists Business as adding Auto Drafts, Ask AI, the Superhuman Mail MCP, Custom Auto Labels with AI, HubSpot and Salesforce integrations, and Recent Opens.
The Superhuman AI Overview help page says Mail and its vendors do not train on your data, that data is encrypted in transit and at rest, and that Write with AI queries are not stored.
Enterprise is listed with single sign-on, advanced security and controls, team analytics, priority support, and a customer success manager.
The suite pricing page lists a $0 Free plan with AI chat and writing corrections, and a Pro plan at $12 per member a month billed annually that includes Grammarly, Docs and Go.
The Help Center says Mail also remains available as a standalone product and that existing subscriptions are not automatically moved to the suite.

Limitations

On the suite pricing page, Mail is included only from Business ($33 a month billed annually); the suite Free and Pro plans do not include Mail. Starter and Business are capped at 25 seats on the Mail plans page, and all prices are per member.
Suite usage credits for Go show only 'Limited trial' on Pro, Business and Enterprise with no amounts, and usage tracking is marked 'Coming soon'. The Mail plans page shows a Monthly/Annual toggle with annual billing '17% off' but lists no monthly prices; the monthly prices ($30 and $40) appear only in the Help Center.
The Mail plans page does not mention a free plan or trial, and its page description refers to 'Free, Pro, and Enterprise' plans that the page does not show.
Vendor pages disagree on data use: the Mail AI help page says neither Mail nor any vendor trains on your data, while the company privacy policy says Superhuman uses information to train its AI models and offers a training control in account settings.
The suite pages disagree on Free-plan writing corrections ('20+ languages' on the plans page, '6 languages' in the Help Center). The pages read did not state refund terms; the cancellation article points to hello@superhuman.com.
