An AI productivity suite launched when the company behind the well-known writing assistant Grammarly renamed itself and its brand to Superhuman in October 2025. Four products now sit under a single brand: the fast email client Superhuman Mail, the collaborative document workspace Docs (formerly Coda), the writing assistant Grammarly, and a new AI assistant called Superhuman Go. Its defining trait is that Go runs on top of every app and tab you already use, helping with inbox processing, document writing, and everyday communication across them. It is available on Mac, Windows, iOS, and Android, and connects with major tools such as Gmail, Drive, Jira, and Slack.
Key Features
- Superhuman Go — an AI assistant that works across apps: Runs in the browser extension, on the desktop, and on mobile, surfacing inline suggestions right next to what you are writing. It also answers context-aware questions in chat, and offers Daily Briefs and Google Calendar integration
- Superhuman Mail — fast inbox processing: Includes Auto Drafts that read context and prepare replies, Share Availability for sending booking links, and Split Inbox for separating messages by importance. Its keyboard-first design is built squarely around making email handling faster
- Docs — a workspace that unifies documents and data: Handles documents, tables, kanban boards, and forms on a single page. Descended from Coda, it lets you combine formulas and automations to shape a document into something closer to an internal tool
- Grammarly’s writing assistance carried over: Grammar and tone corrections, rewrites, translation across 15+ languages, and AI-generated text detection remain available. What is new is the ability to tune which suggestions you want to see
- Extensible through agents and connectors: Over 100 prebuilt agents and a connector library are available, and you can assemble your own agents without code. Mail MCP and Docs MCP also let external AI clients operate the products
- Integrations with major tools: Read-only CRM connections for HubSpot, Salesforce, and Pipedrive (on higher plans), plus the ability to pull Jira, GitHub, and Figma data into documents

Pros & Cons
✅ Pros
- Consolidates mail, documents, proofreading, and an AI assistant into one subscription instead of several
- Because Go works across apps, you do not have to switch to a dedicated tab every time you want AI help
- Inherits Grammarly’s proofreading quality, making it strong for writing and polishing English
- The free plan lets you try the core of Grammarly, Docs, and Go
- MCP support means external AI clients can work with your mail and documents
⚠️ Cons
- Superhuman Mail is only available on the Business plan ($33 per member per month billed annually) or above, which is costly if email is all you want
- The rebrand is recent, so old and new names (Grammarly, Coda, Superhuman Mail) still appear side by side and information can be hard to follow
- The writing assistance is strongest for English; Japanese proofreading is not as accurate
- The breadth of the suite means it takes time to grasp the whole picture and use it well
- Because it sits alongside your work and assists with on-screen input, organizations should review its data handling policy in advance

Who Is It For
- People who write English email and documents daily and want proofreading and drafting consolidated in one place
- Business users who lose time to inbox processing and want AI drafts and prioritization to speed it up
- Teams already using Grammarly that want to bring documents and email under the same roof
- Anyone who wants to stop hopping between AI tools and keep the work on the screen they are already on
- Developers who want to operate mail and documents from their own AI client via MCP
Summary
Superhuman bundles three proven products — Grammarly, Coda, and Superhuman Mail — under one brand and adds Go, an AI assistant that works across apps. For anyone looking to consolidate an environment built up from separate tools, it is a strong option. On the other hand, it is worth confirming in advance that email is limited to the Business plan and above, and that Japanese proofreading is not as accurate as English. A practical approach is to try Grammarly, Docs, and Go on the free plan first, then consider the Business plan once you want to hand over email as well.
