Superhuman is the productivity suite built by Superhuman Platform Inc. (formerly Grammarly), combining Superhuman Docs, Superhuman Mail, the Grammarly writing assistant and the Go agent into one subscription. It suits teams on Gmail or Outlook who want AI that acts inside the tools they already use rather than in a separate chat window.

Superhuman is an AI productivity suite that spans documents, email and cross-application agents. The name carries a history that matters for anyone evaluating it today: until late 2025 "Superhuman" referred to a single keyboard-driven email client, but the company behind Grammarly acquired that email client in July 2025, renamed itself Superhuman on 29 October 2025, and folded three previously separate products into one subscription. The operating entity is now Superhuman Platform Inc., described in its own privacy policy as the former Grammarly, with Grammarly Inc., Coda Project LLC and Superhuman Labs LLC among its subsidiaries. If you arrived expecting only an inbox, the current product is considerably wider than that.
What the suite offers today is four surfaces that share one account and one bill. Superhuman Mail is the AI-native inbox for teams on Gmail or Outlook. Superhuman Docs is the collaborative workspace formerly known as Coda, renamed on 8 July 2026. Grammarly remains the writing assistant under its original product name. Superhuman Go is the newest piece, an agent that annotates your writing and acts on your behalf across the applications you already have open. Around them sit Calendar, Databases and the Superhuman Store, a marketplace of agents and connectors. The unifying argument is that AI should reach into the tools where work actually happens instead of waiting in a separate chat window for you to paste context into it.
The suite's capabilities divide cleanly along its product lines, and it helps to evaluate them separately because the plans unlock them at different prices.
Mail is built around the observation that the urgent buries the important. Split Inbox separates messages from your team, your VIPs and the tools you depend on into distinct streams, so a full inbox does not stop you from answering the three messages that matter. Follow-up Reminders attach a deadline to outgoing mail: choose an interval when you send, and if no reply arrives the message resurfaces. Snippets automate repeated typing, from a single phrase to an entire message, and can carry attachments and add CC or BCC recipients automatically. Send Later, Snooze and Instant Reply round out the timing controls, while read statuses show whether a recipient opened your message and on which device, which changes how you word a follow-up. Team Comments let colleagues discuss a live view of an email thread, and notably those colleagues do not need to be Superhuman users themselves.
Go is positioned as bringing AI out of the chat and into the places you actually work. Its defining behaviour is that it does not wait to be asked. It watches for opportunities to help you say something better or do something faster, annotating in real time wherever you write and flagging where you could be clearer, more convincing, or simply wrong. It sorts incoming mail and pre-drafts replies in your own voice with your own context. Around meetings it can crowdsource an agenda beforehand and auto-assign tasks when the meeting ends. Because it connects to your data sources, it can take on more involved work such as assembling a team project from scattered material. Third-party reporting confirms the connector list includes Jira, Gmail, Google Drive and Google Calendar.
Docs is the product with the longest lineage, having spent a decade as Coda. Its pitch is that a document should hold more than text: projects, workflows, data and tools live on the same surface as the prose describing them. Docs AI goes past question answering to build with you, assembling text, tables, formulas and buttons into interactive team solutions from a plain description. Docs MCP opens the workspace to outside AI tools, so Claude, ChatGPT or Cursor can draft a brief or create a table that lands directly in the document rather than in a transcript you then copy by hand. The July 2026 relaunch added AI Views, a closed beta that builds custom interfaces live on top of your data, and Superhuman Databases, another closed beta rated for up to one million rows.
The Grammarly writing assistant continues under its own name inside the suite, and several of its capabilities appear as named features on the Superhuman homepage. Humanizer rewrites AI-generated text so it reads naturally while preserving the original meaning. Knowledge Checker verifies claims against your company's own data and corrects them inline. AI Detector scores how closely a passage resembles AI writing. Alongside them sit Daily Briefs, Auto Labels, Auto Archive and Auto Drafts. The Superhuman Store extends this further: it lists first-party agents such as Plagiarism Checker, Reader Reactions and Resume Builder, and third-party entries including Canva from Canva Developers, ZoomInfo and SimplaDocs. The company advertises more than a hundred ready-made agents, and users can build their own by describing what they need in chat or stepping through a visual builder, then share the result with teammates or publish it to a company directory.
Executives and founders drowning in inbound. This is the audience the email client was originally built for and it remains the sharpest fit. When your inbox contains investors, candidates, customers and partners in one undifferentiated stream, Split Inbox plus reminders is a genuine workflow change rather than a convenience.
Client-facing teams where response latency costs money. Read statuses, Send Later and shared Team Comments matter most when a late reply loses a deal. The ability to loop in a colleague who does not have a licence removes the usual friction of forwarding chains.
Teams consolidating scattered documentation. Docs suits groups currently spreading a single project across a spreadsheet, a wiki page and a chat thread. The full-page tables and database capability are aimed at teams whose "documents" are really structured data wearing a document costume.
Organisations standardising written communication. Where a company cares that outbound writing is consistent, on-brand and factually grounded, the combination of Grammarly's style enforcement with Knowledge Checker's verification against internal data addresses a problem that a generic chatbot does not.
Individuals who want AI assistance without changing tools. Go's cross-application model appeals to people who resent the copy-paste tax of moving text into a chat window and back. The free tier makes this the lowest-commitment way to try the suite.
Regulated or security-conscious enterprises. SAML single sign-on, SCIM provisioning, audit events, data loss prevention, BYOK encryption, a SOC 2 Type 2 report and HIPAA compliance are all real capabilities here, but they live exclusively in the Enterprise tier and should be treated as a procurement conversation rather than a self-serve purchase.
1. Work out which product you actually need. This is the step most new users skip, and it is where money is wasted. The suite plans and the individual product plans are separate pricing tracks with different contents. If you only want the email client, the Mail-specific plans start lower than the suite plan that includes Mail.
2. Confirm your email provider first. Mail is built for teams that use Gmail or Outlook. If your mail lives elsewhere, this part of the suite is not available to you and no plan changes that.
3. Start on the free tier. The free plan costs nothing and already includes Grammarly, Docs and Go. This lets you test the writing assistance and the agent behaviour against your real work before any payment, though note that Mail is not part of it.
4. Connect your data sources to Go. Go's usefulness scales with what it can see. Connecting calendar, drive and issue tracking turns it from a writing checker into something that can prepare you for a meeting or file a ticket.
5. Set your AI training preference deliberately. The platform states it uses collected information to train its AI models and that you decide whether your user content is included by adjusting the training control in your account settings. Find that setting before you put sensitive material into the product rather than after.
6. Configure Split Inbox around your actual priorities. The default split is a starting point. The value appears once the streams match how you genuinely triage — team, VIPs, and the tools that generate notifications you cannot ignore.
7. Build snippets from what you already repeat. Rather than inventing templates, watch for the third time you type something similar and turn that into a snippet. Shared snippets propagate consistent messaging across a team.
8. Decide who needs to be a Doc Maker. Docs bills per Doc Maker, not per member of your organisation. Mapping who genuinely creates versus who reads is the single largest lever on what Docs costs you.
Treat the two pricing tracks as a decision, not a detail. Suite Business at thirty-three dollars per member includes Mail, Grammarly, Docs and Go. Mail's own Starter plan at twenty-five dollars gets you the inbox alone. Which is cheaper depends entirely on whether your team will use the other three products, and buying the wrong track is the most common way to overpay here.
Use annual billing only once you are certain. Annual billing is meaningfully cheaper across the board, but the platform's terms state that purchased generative AI capacity is tied to your current subscription, is not transferable, and is not refunded when a subscription expires or terminates. Commit after the trial period has told you something, not before.
Do not treat AI output as verified. The terms are unusually direct on this point: outputs come as-is, with no warranty as to factual accuracy, and the company explicitly says its generative AI should not be relied on as a single source of factual information. Knowledge Checker exists precisely because this is a real failure mode.
Let read statuses inform tone, not pressure. Knowing a message was opened on a phone and not answered is useful context for a gentle follow-up. Using it to imply you are monitoring someone is a fast way to damage a relationship.
Audit your Doc Maker seats quarterly. Because the billing unit is creators rather than viewers, seat counts drift as people's roles change. A periodic review is cheap and the savings are real.
Pilot the closed betas separately. AI Views and Superhuman Databases are explicitly labelled closed beta. Plan any workflow that depends on them as an experiment with a fallback, not as production infrastructure.
Check the arbitration opt-out window if it matters to you. The terms contain a binding arbitration agreement with a class action and jury trial waiver, and a thirty-day window to opt out. Whether you use it is a business decision, but the window is short and it starts running when you accept.
The clearest fit is a team already standardised on Gmail or Outlook, spending several hours a day in written communication, and willing to pay a premium for speed. The product has never competed on price and does not pretend to.
It also suits organisations that were already Grammarly or Coda customers. For them the suite is less a new purchase than a consolidation, and the pricing reflects an intent to reward using more than one product.
It fits knowledge teams whose documents are really structured work: trackers, intake workflows, project plans. Docs was built by people who spent ten years arguing that a document should be able to do more than hold text, and that conviction shows in the product.
It is a poor fit for anyone whose email is not on Gmail or Outlook, for whom Mail is simply unavailable. It is also a poor fit for individuals who want a cheap AI writing tool and nothing else, since the suite's value proposition depends on breadth. Teams needing compliance guarantees should be aware those sit behind an Enterprise conversation, and price-sensitive small teams will find the per-member figures add up quickly.
Mail runs on the web and on mobile, with native applications on both major mobile platforms. The iOS application is published by Superhuman Labs Inc. and was updated in mid-August 2026, indicating active maintenance rather than a coasting codebase. The Android application is published by Superhuman Labs and reports fifty thousand or more downloads. There is also a separate enterprise mobility management build of the mobile client for organisations that distribute applications through a managed channel.
Docs is a browser-based workspace, and following the July 2026 rename its home moved to a Superhuman-hosted address, while the previous Coda web address continues to serve its own site with a rename banner. Go works as an extension layer across the applications you already use rather than as a standalone destination, which is the entire point of its design. Connectivity outward runs through MCP for both Mail and Docs, letting external AI tools reach into either product.
The single most important platform constraint is not an operating system at all: Mail requires Gmail or Outlook. Treat that as the first qualifying question.
Two separate pricing tracks exist, and confusing them is the main source of error.
The suite plans. Free costs nothing and covers Grammarly, Docs and Go. Pro is twelve dollars per member per month billed annually, or fifteen billed monthly, and adds unlimited paragraph rewrites and translations, AI text detection, plagiarism correction, brand style enforcement, custom domain publishing, unlimited document size and thirty-day version history. Business is thirty-three dollars per member per month billed annually, or forty billed monthly, and is the first tier that includes Mail at all, alongside CRM visibility for HubSpot, Salesforce and Pipedrive, unlimited automations and data sync from Jira, GitHub and Figma. Enterprise is custom-priced and adds analytics, advanced security and admin controls, SAML single sign-on, custom roles, data loss prevention, BYOK encryption and a dedicated support team.
The Mail-only plans. Starter is twenty-five dollars per member per month billed annually, or thirty billed monthly, covering email productivity, Superhuman AI, team collaboration, calendar and scheduling and unified admin and billing. Business is thirty-three annually or forty monthly, with a further fifteen percent discount for teams of five or more, and adds the most advanced AI, Auto drafts, Ask AI, the Mail MCP, custom auto labels and CRM integrations. Enterprise requires a sales conversation. Annual billing is marked as saving seventeen percent.
The Docs billing unit deserves separate attention. Docs charges per Doc Maker rather than per member. Pro is twelve dollars and Business thirty-three, on the same annual and monthly split, but only creators consume a seat. Docs AI is available during its beta to Doc Makers specifically. Compliance artefacts including the SOC 2 Type 2 report and HIPAA compliance appear only at the Enterprise level.
Prices reflect the pricing pages as accessed in late August 2026 and are quoted in US dollars; check the current pages before budgeting.
For email specifically, the established comparison set for any AI email client includes Spark Mail and Canary Mail, alongside Gmail's own increasingly capable AI features — a genuine consideration given that some reviewers note functional overlap with Gmail itself. For workspace and documents, Notion, Confluence and Airtable occupy adjacent ground, and Coda historically published comparisons against exactly those products. For writing assistance, the market is broad and includes both dedicated assistants and general-purpose chat models.
The honest framing is that Superhuman's competitive claim is no longer "the fastest email client" but "one subscription across writing, documents, mail and agents." Judged product by product, each faces credible competition. Judged as a bundle, the comparison set is much thinner, which is precisely the strategic bet the company made when it consolidated three acquisitions under one name.
Mail requires Gmail or Outlook. This is a hard constraint, stated plainly on the product page, and no plan removes it.
The product identity is genuinely confusing right now. A company renamed itself after a product it acquired, kept the old brand alive as a product name, and renamed a second acquisition a year later. Third-party listings have not caught up: the Product Hunt profile still describes Superhuman purely as an email client. Expect outdated descriptions in reviews and comparisons written before mid-2026.
Price is the most consistent user complaint. Independent review summaries put price at the top of the criticism list, alongside a pricing change that some users regarded as unfavourable to existing customers, a missing unified inbox, functional overlap with Gmail, and occasional rough edges in AI tone and mobile interaction.
User content is used for AI training unless you change a setting. The privacy policy states the company trains its AI models on collected information and that a control in account settings governs whether your user content is included. The company does say it restricts its AI service providers from training their models on user content and that it does not make money by selling user content, but the default direction of the primary control is something each organisation should verify for itself.
Generative AI output carries an explicit disclaimer. Outputs are provided as-is and with all faults, with no warranty of factual accuracy, and the terms tell users not to rely on the AI as a single source of factual information.
Several headline capabilities are closed beta. AI Views and Superhuman Databases both carry that label, as does Docs AI during its beta period. Build contingencies accordingly.
Vendor metrics are self-reported. Claims of saving four hours per week, twenty million hours annually across teams, and forty million people and fifty thousand teams using the suite come from the company and have not been independently audited. Note also that the forty million figure counts the whole suite including Grammarly, which is a different population from the fifty thousand or more downloads recorded for the Android mail client.
Purchased AI capacity is non-refundable. Additional generative AI units are tied to the subscription, non-transferable, and not refunded on expiry or termination.
Reported acquisition figures are frequently misstated. The widely repeated eight hundred and twenty-five million dollar number was the email client's last valuation before acquisition, not a purchase price; the financial terms of the deal were never disclosed.
No. It was one until 2025, and the email client still exists as Superhuman Mail, but the name now refers to a suite covering documents, writing assistance, cross-application agents, calendar and databases. The company behind Grammarly acquired the email client in July 2025 and adopted its name in October 2025.
Grammarly the company renamed itself Superhuman; Grammarly the product kept its name and remains part of the suite. Coda was renamed Superhuman Docs on 8 July 2026, keeping its features while gaining a rebuilt AI assistant, an open MCP integration and new database capabilities.
The former Coda web address still resolves and serves its own site with a rename banner rather than redirecting away, and the workspace's new home is on a Superhuman-hosted address. Because behaviour around link handling can change during a transition like this, verify with your own links rather than assuming.
No. It is built for teams that use Gmail or Outlook. Other providers are not supported, and this is the first thing to check before evaluating anything else.
Yes. The free suite plan costs nothing and includes Grammarly, Docs and Go, with AI chat across applications, writing support in over twenty languages, and collaborative documents with tables, charts, boards and forms. It does not include Mail, which starts at the Business suite tier or on Mail's own separate plans.
On the suite track, Pro is twelve dollars per member per month billed annually and Business is thirty-three, with monthly billing at fifteen and forty respectively. Mail sold on its own starts at twenty-five per member per month billed annually. Docs bills per Doc Maker rather than per member. Enterprise pricing is custom.
The privacy policy states the company uses information it collects to train its AI models, and that you can decide whether your user content is used by adjusting the training control in your account settings. It also states that it restricts its AI service providers from training their models on user content. Check the setting in your own account, since defaults matter more than policy language here.
You do. The terms state you retain all right, title and interest in your user content, with the platform receiving only the licence it needs to operate the service. Separately, AI outputs are provided as-is with no warranty of factual accuracy, and the terms advise against treating them as a single source of truth.
On Product Hunt it holds a 4.8 rating from 89 reviews, with praise concentrated on keyboard shortcuts, Split Inbox, snippets and reminders, and criticism concentrated on price, a contested pricing change, a missing unified inbox and rough edges in AI tone. The mobile clients rate 4.61 from 3,587 ratings on the Apple store and 4.5 from 678 reviews on the Google store, so the direction is consistent across channels even though sample sizes differ substantially.
The compliance capabilities exist but sit at the Enterprise tier: SAML single sign-on, SCIM provisioning, audit events, advanced access controls, a SOC 2 Type 2 report and HIPAA compliance are all listed there and not on lower plans. Treat compliance as a sales conversation rather than something you can self-serve.
