Superhuman

What it is

Superhuman is the company that used to be called Grammarly. It bought the Coda docs product (closed January 2025, bringing Shishir Mehrotra in as CEO) and the Superhuman email client (July 2025), then took the Superhuman name for the whole company in October 2025. The Grammarly writing assistant kept its name and is now one product in a four-part suite:

• Grammarly — the writing assistant most of your staff already has installed.
• Superhuman Go — an AI assistant and agent layer that sits wherever you type, in the browser extension and in desktop apps for Mac and Windows plus an iOS app.
• Superhuman Mail — the premium email client for Gmail and Outlook.
• Docs — the former Coda, now sold under the suite.

The company says it serves more than 40 million people and 50,000 organizations. It is an independent private company and an acquirer, not an acquisition target: it raised $1 billion in growth financing from General Catalyst in May 2025, agreed to buy the AI-detection company GPTZero in June 2026, and has since bought the meeting notetaker Fathom.

What changed for Grammarly buyers

The reason this page exists is the renewal. Grammarly’s enterprise page now says Grammarly “is now delivered through Superhuman Go”, and an Enterprise renewal arrives as a Superhuman deal. Three dates explain the shift:

• 29 October 2025 — Go launched, free to all users until 1 February 2026, with connector agents and partner agents.
• 23 February 2026 — partner agents from Box, Gamma and Wayground arrived in the Superhuman Agent Store, with an Agents SDK and MCP client in private beta for companies building their own.
• 12 August 2026 — Go 1.0. Anyone on a paid plan can build custom agents that fire on a schedule, an event or while you type, and that underline your text with suggestions the way Grammarly underlines a typo. The same release shipped connectors for Outreach, Apollo, ZoomInfo, Gong, Snowflake, Databricks and others, alongside the earlier Salesforce, HubSpot, Slack and Atlassian connectors.

A use case worth buying it for

Keeping CRM notes honest without asking reps to open another tab. A Go agent connected to Gong and Salesforce reads the call transcript and suggests fixes to the call notes the rep is typing into Salesforce; once the suggestions prove reliable, the rep lets the agent write the call log. The work happens in the text box the rep already uses, which is the one thing a chat-window assistant cannot copy.

Pricing

Per member per month, from Superhuman’s plans page:

• Free — Grammarly, Docs and Go with limited chat. Grammarly’s own page caps AI prompts at 100 a month.
• Pro — $12 billed annually, $15 monthly. Grammarly, Docs and Go; connectors and custom agents; 2,000 Grammarly AI prompts per member a month.
• Business — $33 billed annually, $40 monthly. Adds Superhuman Mail and connectors for Jira, Linear, Asana, Confluence and Zendesk.
• Enterprise — custom. Adds Salesforce, HubSpot, Workday and ServiceNow connectors, SAML SSO, SCIM, data loss prevention, BYOK encryption, audit logs and unlimited Grammarly prompts.

The realistic band for a company rolling Go out to everyone is $12–$33 per member a month at list, and anything with SSO is an Enterprise quote. Superhuman says Go runs with soft usage limits today and that usage-based pricing will follow with notice, so a fixed per-seat number is not guaranteed past this contract.

Best for

People-ops, RevOps and legal-ops leaders whose company already pays for Grammarly across most of its staff, and who want AI help inside the text fields people already type in rather than another chat window.

Alternatives, and when to pick them instead

• Microsoft 365 Copilot — the market-share default at $30 per user a month (enterprise) or $21 (Business). Pick it when your documents and email live in Microsoft 365.
• ChatGPT — the other market-share leader; Business is $20 per seat a month annually. Pick it when people need a general-purpose assistant for research and analysis more than help while they type.
• Claude — Anthropic’s assistant. Pick it when long documents, careful reasoning or coding matter more than inline suggestions.
• WRITER — pick it when the requirement is brand and compliance governance on generated content, owned by marketing.

The rule: Superhuman Go is a complement to a frontier assistant, not a substitute. If you can afford only one AI seat per person, buy the frontier assistant; buy Go when Grammarly is already a line item and the step up to Pro or Business is cheaper than a second assistant.

Watch-outs

• The pricing story is unsettled. Go went from free to paid in February 2026, and Superhuman has said usage-based pricing is coming. Guard: fix the per-member price and any usage caps for the full term in the order form, with a cap on increases at renewal.
• Its own pages disagree on AI training. The Superhuman plan table shows Business as opt-out and Enterprise as off by default, while the Go FAQ and Grammarly’s enterprise page say business customers have training off by default. Guard: get “customer content is not used for model training” written into the contract or DPA, not inferred from a pricing page.
• Connectors widen what the assistant can read. A Go agent wired to Salesforce or Gong can surface account data in any text box a user types into. Guard: start with read-only connectors for one team, check that connector permissions follow each user’s source-system access, and add the rest after a month without incidents.
• Mail is not in Pro. Teams that buy Pro expecting the Superhuman email client find it starts at Business. Guard: price the Business tier only for the people who will use Mail and keep everyone else on Pro.
