Superhuman

What is Superhuman?

Superhuman is an AI productivity suite built around Superhuman Mail, an email client known for speed, keyboard shortcuts and AI drafting for Gmail and Outlook accounts. The Superhuman name now covers four products: Superhuman Mail, Grammarly, Superhuman Docs and Superhuman Go, an AI assistant that works across apps and browser tabs. Mail runs on the web, Mac, Windows, iOS and Android, and the company claims it helps users save four hours every week.

Superhuman Mail started as an independent startup founded by Rahul Vohra, which TechCrunch reported had raised over $114 million at an $825 million valuation. Grammarly, which had bought Coda in December 2024, acquired Superhuman on 1 July 2025. On 29 October 2025 Grammarly renamed the whole company Superhuman, with Shishir Mehrotra as CEO. Grammarly remains a product inside the suite, and Coda’s collaborative workspace now appears as Superhuman Docs. The company reports 40 million daily users and 50,000 organisations.

Key Features

• Split Inbox: Split Inbox divides incoming email into separate priority streams automatically. You clear the most important group first and batch lower-value mail for later, which keeps the main view short and focused.
• AI drafting and Instant Reply: Superhuman Mail writes replies in your own tone and can draft, and optionally send, complete emails on your behalf. Instant Reply adds one-click suggested responses for quick messages that need only a short answer.
• Ask AI and summaries: Ask AI lets you question your inbox in plain language instead of building manual searches. Reviewers at Gmelius also describe thread summaries that collapse long conversations into a short overview before you reply.
• Keyboard shortcuts: Superhuman Mail is designed to be driven almost entirely from the keyboard. Capterra and Gmelius reviewers single out the shortcuts as a main reason the client feels so fast once you learn them.
• Read Statuses, reminders and Snooze: Read Statuses show when a recipient opens your email and on which device. Follow-up reminders and Snooze bring messages back at a chosen time, so threads that need a reply do not slip.
• Snippets and Send Later: Snippets store phrases, paragraphs or whole emails that you insert with a few keystrokes, and teams can share a snippet library. Send Later schedules messages to arrive when the recipient is more likely to read them.
• Team collaboration: Superhuman Mail supports live email sharing with comments and shows when a teammate is already replying. That cuts duplicate answers on shared customer or deal threads without adding a separate collaboration tool.
• Superhuman Go: Superhuman Go is an AI assistant that works inside other apps through desktop apps, Chrome and Edge extensions and mobile apps. It runs agents such as Grammarly, Email Assistant, Knowledge Checker and Daily Brief, and you can build custom agents without code.
• Grammarly and Superhuman Docs: Every Superhuman plan includes Grammarly writing help and Superhuman Docs. Docs offers tables, charts, Kanban boards and forms, plus more than 800 integrations that sync data from tools like Jira, Salesforce and Asana.

Pros

• Fast email triage: Superhuman Mail is built for clearing email quickly, and the company claims users save four hours every week. Capterra reviewers praise its speed and keyboard-first workflow, with an average of 4.8 out of 5 across 23 reviews.
• AI built into the inbox: Superhuman Mail includes AI drafting, Instant Reply, summaries and Ask AI on the Business plan. You do not need a separate AI writing tool, because Grammarly proofreading comes in the same subscription.
• Keeps your existing email: Superhuman Mail sits on top of Gmail and Outlook accounts, so you keep your address and provider. Apps for web, Mac, Windows, iOS and Android carry the same shortcuts and triage habits across devices.
• Free way in: Superhuman offers a free plan that includes Grammarly, Docs and Go. You can try the AI assistant and writing tools before paying, although Mail itself requires the Business plan.
• One bill for several tools: Superhuman bundles mail, writing help, docs and an AI assistant into one Business subscription. Teams already paying separately for Grammarly and a docs tool may be able to consolidate their software spend.
• Enterprise controls: Superhuman Enterprise adds SAML single sign-on, custom roles, data loss prevention and BYOK encryption. The company says AI training on customer content is off by default for Enterprise users.

Cons

• High price for email: Superhuman Mail costs $33 a month billed annually, or $40 monthly, on the Business plan. Capterra and Gmelius reviewers both describe the price as steep for an email client, especially across a whole team.
• No mail-only budget tier: Superhuman no longer lists a mail-only Starter plan on its official pricing page. Capterra and Gmelius still show older Starter prices of $25 or $30, which makes like-for-like comparisons confusing.
• Learning curve: Superhuman Mail’s keyboard-first design takes practice before it pays off. Capterra reviewers mention a steep learning curve, so people who prefer the mouse may not see the promised time savings straight away.
• Limited mail integrations: Superhuman Mail’s HubSpot, Salesforce and Pipedrive connections are read-only on the Business plan. Gmelius also notes there is no shared inbox, so support teams may still need a tool such as Front.
• No unified inbox: Superhuman Mail lacks a unified inbox across multiple accounts, according to Capterra reviewers. People juggling several work and personal addresses must switch between accounts rather than seeing one combined list.
• Confusing brand change: Superhuman now names both the email client and the wider company formerly called Grammarly. Searches for help or pricing often surface outdated pages about the old standalone email app, so check the date of any guide.

Who is Using Superhuman?

• Founders and executives: Clearing high-volume inboxes quickly with shortcuts and AI.
• Sales teams: Drafting replies with CRM context from HubSpot or Salesforce.
• Operations teams: Running shared docs, trackers and approval workflows.
• Writers and students: Using Grammarly and Go for writing feedback.

Pricing

Superhuman is freemium, with a free suite plan and Superhuman Mail included from the $33 Business plan (official prices, October 2026).

Directories still show older standalone Mail plans, with Capterra listing Starter at $25 and Business at $33, and Gmelius quoting $30 and $40. Seat counts and bundles may change after the rebrand, so read the official plans page carefully before rolling Superhuman out to a team.

What Makes Superhuman Unique?

Superhuman Go carries the company’s AI into other apps, so the assistant that drafts in Superhuman Mail also works in Slack, Jira, Asana and document editors through desktop apps and browser extensions. Combined with Grammarly’s writing feedback and the 800+ integrations in Superhuman Docs, the suite links email, writing and team knowledge rather than treating email as a separate island. The mail client itself remains keyboard-first, built for triage speed over feature breadth.

Compatibilities and Integrations

• Email providers: Gmail and Outlook accounts.
• Platforms: Web, Mac, Windows, iOS and Android, with Go also available as Chrome and Edge extensions.
• CRM: Read-only HubSpot, Salesforce and Pipedrive integration on the Business plan.
• Docs integrations: 800+ integrations with two-way sync for tools such as Jira, Salesforce and Asana.

How We Rated It

Summary

Superhuman suits professionals and teams who live in Gmail or Outlook and want a faster, AI-assisted inbox alongside Grammarly and shared docs. The suite is broad, and Superhuman Go extends the same AI into other apps. Its main limitation is cost, since Mail sits on the $33 Business plan and directory prices still conflict. Try the free plan for Go and Grammarly first, then upgrade only if your inbox volume justifies Mail.
