Superhuman now sells three price lists, and every price on them is per member. I read Superhuman's and Grammarly's pricing pages and Superhuman's help center on 24 October 2026, on the US version of each page, so every figure here is in US dollars:
- The suite: Free, Pro at $12 a month billed yearly or $15 monthly, and Business at $33 or $40. Enterprise is quoted.
- Superhuman Mail on its own: Starter costs $25 billed yearly or $30 monthly, and Mail Business matches the suite's $33 or $40.
- Grammarly on its own: free, or Pro at $144 a year. Pro also bills by the quarter at $60, and by the month at $30.
What you want picks the list: the email app, the writing help or both. Watch for one trap. Pro at $15 a month leaves out Grammarly Pro, and adding it costs another $15.
Superhuman pricing in five lines (October 2026)
- Three price lists, per member, US prices read 24 October 2026: the suite (Pro $12 billed yearly or $15 monthly, Business $33 or $40), Superhuman Mail alone (Starter $25 or $30), and Grammarly alone (Pro $144 a year or $30 a month).
- Monthly Pro leaves out Grammarly Pro. Adding it costs $15 more a member, so the $144 yearly plan is the one with Grammarly Pro inside.
- Mail is not in Free or Pro. Inside the suite it starts at Business, which costs exactly what Mail Business costs on its own.
- Free covers Grammarly, Docs and Go with tight limits. Mail has no free plan, and the suite has no trial.
- No suite discounts, and suite refunds only where the law requires them. Students get 50% off Grammarly Pro, not the suite.
How I read the prices
The price lists come from four kinds of page, all read on 24 October 2026:
- The suite page and the Go and Docs plan pages. All three carry the same four tiers, and only Go and Docs print the Grammarly fine print.
- Mail's own plan page, in its Annual and Monthly tabs.
- grammarly.com/plans and grammarly.com/pro, because Grammarly still runs its own price list.
- About thirty help center articles, where the rules on seats, refunds and switching live.
The suite page has no billing toggle. Its big number is the yearly rate per month, and the monthly price sits in small type underneath. From an Indian connection the suite page also prints rupees and grammarly.com adds a regional plan, so everything here comes from the US pages.
In July 2025 Grammarly announced it was acquiring Superhuman, the email app, and on 29 October 2025 it renamed the whole company Superhuman. The email app is now Superhuman Mail, Coda became Superhuman Docs on 8 July 2026, and Grammarly is still the name of the writing product.
Superhuman plans at a glance
Seven plans have a public price, and suite Enterprise is quoted. Here they are per member, in US dollars, as of 24 October 2026:
| Price list | Plan | Billed yearly, per month | Billed monthly | What it includes | Seats |
|---|---|---|---|---|---|
| Suite | Free | $0 | $0 | Grammarly, Docs and Go, with limits; no Mail | Not stated |
| Suite | Pro | $12 ($144 a year) | $15 without Grammarly Pro; $30 with it | Grammarly, Docs, and Go with Email Assistant; no Mail | Up to 149 paid |
| Suite | Business | $33 ($396 a year) | $40 | Mail with Business features, plus Grammarly, Docs and Go | Up to 149 paid |
| Suite | Enterprise | Custom | Custom | SSO, SCIM, data loss prevention, BYOK encryption | Not stated |
| Mail alone | Starter | $25 ($300 a year) | $30 | The Mail app with most Superhuman AI | Up to 25 |
| Mail alone | Business | $33 ($396 a year) | $40 | Adds Auto Drafts, Ask AI and CRM connections | Up to 25 |
| Grammarly alone | Free | $0 | $0 | 100 AI prompts a month | Not stated |
| Grammarly alone | Pro | $12 ($144 a year) | $30, or $60 a quarter | 2,000 AI prompts a member a month, plagiarism and AI-text detection | Up to 149 |
From Superhuman's suite, Go and Mail plan pages, grammarly.com/pro and Superhuman's help center, read 24 October 2026. Suite Business's $396 is my arithmetic ($33 x 12); the other yearly totals are printed by Superhuman or Grammarly. Mail also has an Enterprise plan, sold through sales.
Pro at $12 or $15: the monthly price leaves out Grammarly Pro
Pro costs $12 a member a month billed yearly, which is $144 a year, or $15 billed monthly, as of October 2026. It includes Grammarly, Docs and Go. The Mail app is not part of it. Here is what Pro adds over Free:
- Email Assistant, which drafts replies, clears inbox clutter and follows up for you inside Gmail or Outlook. Its drafts are "never sent automatically", and it does not need the Mail app.
- Connectors to your own apps, plus custom agents that the grid marks "Limited".
- Grammarly's paid tools on yearly billing, with unlimited paragraph rewrites and a checker for plagiarism and AI-written text (a $15 add-on on monthly billing).
- Bigger docs, with no size limit and 30 days of version history.
Now the fine print. The suite page prints "$15 when billed monthly" under Pro and stops there. The Go page's compare grid finishes the sentence: Grammarly on Pro is "Included with annual plan or add for $15/member when billed monthly". Superhuman's help center says the same, which makes monthly Pro with Grammarly Pro $30 a member, exactly what Grammarly Pro costs on its own each month.
Paying yearly saves $216 if you want Grammarly Pro, and $36 if you do not.
Here is my arithmetic for one member over twelve months, on the October 2026 prices.
- Pro billed yearly: $144, Grammarly Pro included.
- Pro billed monthly without the add-on: $180. The yearly plan costs $36 less and includes Grammarly Pro on top.
- Pro billed monthly with the add-on: $360, so the yearly plan saves $216, or 60%.
Monthly billing only wins if you leave early: within four months with the add-on, or within nine without it. Superhuman refunds suite plans only where the law requires it, so treat a paid year as spent.
Business at $33 or $40 is where the suite adds Mail
Business costs $33 a member a month billed yearly, or $40 monthly, as of October 2026, under a "Best value" badge. It is the cheapest suite plan with the Superhuman Mail app. Every Mail row on the compare grid, from Auto Drafts and Ask AI to split inbox and team scheduling, is checked for Business and Enterprise only.
The rest of the suite comes along a tier higher. Grammarly is included in both billing states, with no add-on. Docs gets unlimited automations and version history, Go connects more apps and builds more custom agents, and the plan holds up to 149 paid seats with priority support.
Business also connects to HubSpot, Salesforce and Pipedrive from the inbox, though the compare grid labels those integrations "read-only". The card's promise that you will "save 4 hours every single week" is Superhuman's own claim, with no method published.
Suite Business and Mail Business cost the same, and only the suite version brings Grammarly and Docs.
Same $33. Same $40.
Both prices are as of October 2026. Superhuman's help center describes the suite plan as "More advanced Grammarly, Coda, and Go, as well as Mail with Business features" (Coda is Docs' old name), and it allows 149 paid seats to Mail's 25. At the same price I would pick the suite version, unless you qualify for the startup offer in the next section.
Superhuman Mail on its own starts at $25
Mail is still sold separately, and the help center says so plainly: "You can still purchase Mail a la carte at superhuman.com/plans/mail." The page opens on its Annual tab with a "17% off" badge. Here is Starter, the entry plan, as of October 2026:
- Price
- $25 a member a month billed yearly, which is $300 a year, or $30 monthly.
- AI on Starter
- Write with AI, instant reply, auto labels and summaries are all there, which Superhuman calls "most Superhuman AI features".
- Inbox and team
- Split inbox, snippets, snooze, read statuses and booking links come with it, plus team comments.
- Not on Starter
- Auto Drafts, Ask AI, Mail MCP and the CRM integrations need Business, at $33 or $40.
- Works with
- Gmail or Outlook.
Yearly billing saves $60 on Starter ($300 against $360) and $84 on Business ($396 against $480), by my arithmetic, both close to that 17%. Mail has no free plan, and its page showed no trial.
Seats are the one muddle. The compare grid says "Up to 25 seats" on Starter and Business, while the annual-plan help article says "You can have up to 14 people on the annual plan under one subscription", with more through an account manager. A team of 15 to 25 should ask before paying for a year.
Startups can get 12 months of Mail Business free, for up to 5 team members, if they meet Superhuman's four conditions:
- No more than $10M raised in equity funding.
- Fewer than 50 employees.
- An association with one of Superhuman's approved Startup Partners.
- No existing Superhuman Mail subscription.
For student and nonprofit pricing, Mail's pricing article says to email hello@superhuman.com and publishes no discount size.
The Free plan covers Grammarly, Docs and Go, but not Mail
The suite's Free plan costs $0 and includes Grammarly, Docs and Go, as of October 2026. It has no Mail app and no Email Assistant. The compare grid and the help center set these limits.
- Grammarly: Grammarly Free includes 100 AI prompts a month, per grammarly.com, while the suite grid only says "Limited prompts".
- Go chat: "Limited chat access".
- Docs: version history is kept for 7 days, and shared docs have a size cap.
- No connectors, custom agents, AI detection or plagiarism checker.
A shared Free doc locks after a 14-day grace period once it passes 50 objects or 1,000 rows.
A personal doc that nobody else can see has no object or row limit on Free. Share it, and the help center caps it at 50 objects and 1,000 rows, with 1GB of attachments per doc. Go over and a 14-day grace period starts, after which the doc "will become locked and read-only" until you upgrade or trim it back under the cap.
Grammarly on its own: $144 a year, $60 a quarter or $30 a month
Grammarly still runs its own plans page, and grammarly.com/plans does not redirect to Superhuman. Grammarly Pro gives each member 2,000 AI prompts a month and plagiarism and AI-text detection, for up to 149 seats, and Superhuman's help center says it "replaces the Grammarly Business plan". Grammarly Pro bills three ways, as of October 2026.
| Billing | Grammarly Pro price per member | Over a year |
|---|---|---|
| Monthly | $30 a month | $360 |
| Quarterly | $60 every three months | $240 |
| Yearly | $144 a year ($12 a month) | $144 |
Superhuman's help center (How much does Grammarly Pro cost?, updated 12 September 2026) and grammarly.com/pro, read 24 October 2026. The "Over a year" column is my arithmetic; the "Save up to 60%" on the yearly toggle is $144 against $360.
Grammarly Premium survives only in the App Store and Google Play, with 1,000 AI prompts a month. No page I read showed its price, so I print none. Web Premium subscribers have been moving to Pro since March 2025, and Grammarly says "Your billing amount will remain the same."
Trials come and go. Grammarly offers seven-day Pro trials "periodically", and grammarly.com/plans showed one on 24 October 2026 with the $12 struck through. Skip the coupon sites: "Grammarly does not provide discounts in the form of coupons or other codes."
Put the two price lists side by side. Superhuman Pro costs the same $144 a year and includes Grammarly Pro, plus Docs and the Pro tier of Go, by my comparison of the two. Superhuman's help center adds that every Grammarly Pro subscription "comes with Superhuman Go built in". On yearly billing they are close to one purchase. Only Grammarly Pro shows a quarterly price or takes the student discount. If you are still choosing an editor, I compared Grammarly against other AI writing tools separately.
Students can get 50% off Grammarly Pro through SheerID, but nothing off the suite.
Grammarly's SheerID offer covers students, educators, young adults, military, first responders, healthcare workers and seniors, "for a limited time" according to its students article. The terms below are as of October 2026.
- "Save up to $72 (50% off)", which I read as half of the $144 yearly price.
- First subscription period and first seat only.
- Not through the App Store or Google Play.
- Verification can take "up to seven business days".
The suite gets nothing. Superhuman's help center says "there are no discounts available for the Superhuman suite", and Docs' student, teacher and nonprofit discounts have been paused since 30 June 2026. The help center's article on discounts for students, teachers, nonprofits and startups points students to Superhuman Pro at "$12/month (billed annually, $144/year)", which is simply the list price. For the rest of a student's toolkit, see AI tools for students, free tiers first.
Three monthly bills, worked out
Three buyers, priced on the US lists as of 24 October 2026. Every total in this table is my arithmetic on those prices.
| Buyer | Plan | Billed monthly | Billed yearly | What it buys |
|---|---|---|---|---|
| Solo founder in email all day | Mail Starter | $30 a month | $300 a year ($25 a month) | The Mail app with most Superhuman AI |
| Suite Business | $40 a month | $396 a year ($33 a month) | Mail with Auto Drafts and Ask AI, plus Grammarly, Docs and Go | |
| Suite Pro | $15 a month (no Grammarly Pro) | $144 a year ($12 a month) | Email Assistant inside Gmail or Outlook; no Mail app | |
| Five-person agency | Suite Business, 5 seats | $200 a month | $1,980 a year ($165 a month) | Mail, Grammarly, Docs and Go for everyone |
| Mail Starter, 5 seats | $150 a month | $1,500 a year ($125 a month) | Mail only | |
| Suite Pro with Grammarly Pro, 5 seats | $150 a month | $720 a year ($60 a month) | Grammarly, Docs, Go and Email Assistant; no Mail app | |
| Student or writer who only wants Grammarly | Grammarly Free | $0 | $0 | 100 AI prompts a month |
| Grammarly Pro | $30 a month, or $60 a quarter | $144 a year | 2,000 AI prompts a month | |
| Grammarly Pro through SheerID | Not stated | Up to $72 off the first year | First subscription period and first seat only | |
| Superhuman Pro | $15 a month (no Grammarly Pro) | $144 a year | Grammarly Pro, Docs and Go; no student discount |
My arithmetic on Superhuman's and Grammarly's US prices per member, read 24 October 2026. The SheerID line is my reading of Grammarly's "save up to $72"; promo offers cover the first seat only.
The solo founder first has to decide whether they want a new email app at all. If Email Assistant inside the Gmail or Outlook they already use is enough, Pro billed yearly is the cheapest route, $156 a year under Mail Starter. If they want the app, suite Business costs $96 a year more than Mail Starter and adds Auto Drafts, Ask AI, Grammarly and Docs.
The agency pays $480 a year more for suite Business than for Mail Starter across five people. Pro for all five is the cheapest line at $720, as long as the team can live without the Mail app.
The student or writer should start on Grammarly Free. Once 100 prompts a month runs short, the SheerID offer can bring the first year of Grammarly Pro down to $72, by my reading, while Superhuman Pro stays at $144.
Enterprise, Doc Makers and AI limits
Enterprise has no price on any Superhuman page I read. The card says "Custom", and Mail's pricing article sends enterprise questions to sdr-team@superhuman.com. Pro and Business stop at 149 paid seats, so bigger teams land here. Enterprise adds:
- Data loss prevention, plus SAML single sign-on with SCIM provisioning.
- BYOK encryption, which the grid limits to Grammarly and Mail.
- HIPAA for Grammarly, Docs and Go only.
- Model training off by default; on the other plans it is an opt-out.
- A dedicated support team and an assigned customer success contact.
Docs, the product that used to be Coda, bills "per Doc Maker". You pay for the people who build docs. Editors and viewers are free, and workspace admins count as makers. New customers can only get Docs inside the suite bundle, while existing Coda customers keep their pricing for as long as they stay on their current plan.
Superhuman publishes no AI caps as numbers, apart from Grammarly's prompt counts.
Grammarly's prompts are the only hard numbers: 100 a month on Free, 2,000 per member on Pro, 1,000 on app-store Premium and unlimited on Enterprise. The grid puts everything else into words:
- Go's chat on every paid plan reads "Limited free trial of full chat".
- "Usage credits" are a "Limited trial" on paid plans, and usage tracking is "Coming soon".
- Docs AI is in beta with "fair use" on paid plans. Docs paused the old Coda AI credit system in July 2026 and expects "a new credit system in the coming months".
Superhuman's Go 1.0 post of 12 August 2026 says Go launched "with soft usage limits in place" and that usage-based pricing will follow over time, with "clear notice" first. No date.
What the sticker price leaves out
The card price is per member, per month. These rules from Superhuman's help center move the real bill:
- No suite trial and no suite discounts. In the help center's words: "We don't currently offer discounts or free trials for the Superhuman suite."
- Refunds depend on the product. The suite and Grammarly refund "only if required by law", and you keep access to the end of the term. A Mail annual plan can be refunded for the remainder if you give up Mail, and Docs gives prorated account credit.
- Seats prorate up and drop off later. Removals take effect "in the next billing cycle".
- One account runs the suite. A change in your Grammarly account applies across all of it.
- Promo prices end. Subscriptions renew "at the standard rate", and promos cover one period and the first seat only.
- Upgrades cannot shorten your billing period. Pro moves to Business only for a period the same length or longer, at the prorated difference.
- Acquisitions are not plan features. Superhuman announced on 14 September 2026 that it had acquired Fathom and "plans to bring" its notetaking to the suite, and on 30 September that GPTZero is now part of Superhuman. Neither appears on any plan page I read, and Fathom still sells its own plans; I priced what Fathom and Otter charge separately.
The suite takes cards, PayPal, Apple Pay and Google Pay. I explain how per-seat and usage pricing compare elsewhere.
Already paying for Mail, Grammarly or Coda?
Grammarly and Coda customers can stay put. Superhuman's help center says existing Grammarly subscribers keep the same subscription and billing amount, and existing Coda customers are grandfathered while they stay on their current plan. A Grammarly Pro customer can also get into the suite by signing in at superhuman.com; for other Grammarly subscribers that access "is currently unavailable".
Individual Mail subscribers have one route: convert to Superhuman Business at superhuman.com/plans. You pay the full Business price, get "a prorated refund for the unused period of your Mail subscription", and keep your settings and data. Any Mail discount stays behind, and so do Mail credits.
One trap applies to every Mail customer. Buy the suite with a different email address from your Mail account, and Superhuman bills you for both.
Mail team admins get two answers from Superhuman's help center. Its "Superhuman Suite" article says "It's not currently possible to switch an existing or former Mail team to the Business suite", while the billing FAQ, updated 22 September 2026, says a team admin "may switch at no extra cost, or be charged a prorated difference." Confirm with Superhuman before you cancel anything, because a cancelled team Mail plan's data and settings do not transfer to a suite.
What the same inbox money buys at Shortwave and Spark
Here is one seat on the email side of Superhuman next to two rival email apps. I read each tool's pricing page on 24 October 2026; this is a price check, so there is no ranking. For the full field, see ten AI email assistants compared.
| Tool | Plan | Billed monthly | Billed yearly | Free tier | Works with |
|---|---|---|---|---|---|
| Superhuman Mail | Starter | $30 | $25 a month ($300 a year) | None | Gmail or Outlook |
| Superhuman suite | Pro (Email Assistant, no Mail app) | $15 | $12 a month ($144 a year) | Free plan, without Email Assistant | Gmail or Outlook |
| Shortwave | Pro | $18 a seat a month (one price shown, billing period not stated) | Free, with a limited AI usage quota and 90 days of search history | Gmail and Google Workspace natively; other accounts, Outlook included, through Gmail | |
| Spark | Plus | $10 | $8.25 a month ($99 a year) | Free, with unlimited email accounts | Not recorded in my 24 October read |
| Spark | Pro | $20 | $16.58 a month ($199 a year) | The same Free plan | Not recorded in my 24 October read |
Per member or seat per month in US dollars, from each vendor's own pricing page, read 24 October 2026. Shortwave shows one price per plan and states no billing period; Spark opens on yearly billing. Shortwave offers a 14-day free trial, Spark a seven-day trial of Plus and Pro when you subscribe in the app, and Superhuman's Email Assistant a 30-day trial.
Spark puts Auto-Drafts on its Pro plan. Superhuman Mail keeps Auto Drafts for its Business plans, at $33 or $40, while Email Assistant on suite Pro drafts replies inside Gmail or Outlook. On Gmail there is one more route: Google's own AI plans list Gemini in Gmail, which I price in my Gemini pricing explainer.
Which Superhuman plan should you pick?
Is Superhuman worth it? Depends which Superhuman you mean. Pick the product first and the billing period second. I would route buyers this way on October 2026 prices.
- Writing help only: Grammarly Free. If you outgrow it, Superhuman Pro billed yearly costs the same $144 as Grammarly Pro and adds Docs.
- The fast email app: Mail Starter at $25 billed yearly. If you want Auto Drafts in the Mail app, take suite Business, which costs what Mail Business costs and includes more.
- A team that writes and emails all day: suite Business, billed yearly.
- A student: Grammarly Pro through SheerID, because the suite has no student discount.
- 150 seats or more, or a hard SSO requirement: Enterprise, by quote.
If you are weighing a general AI chat plan instead, my guide to the best AI subscription covers those plans.
If the inbox is the reason you are pricing Superhuman, check whether you need a new email client at all. Superhuman's own Email Assistant sorts mail and drafts replies inside Gmail or Outlook from the Pro plan up. Gravity, my company, is in public beta: you type the job and an agent someone built runs it. The Inbox assistant in Gravity's catalog in October 2026 does a narrower version for Gmail only: every morning it sorts new mail into needs you, FYI, can wait and no action, drafts replies in your voice with free times from your Google Calendar for meeting requests, and sends you a short digest. It never sends an email for you. It does not work with Outlook, it is not an email client, and it does not edit your writing the way Grammarly does. Your first 3 agent runs are free; the Free plan costs $0 with no card, and Mini Pilot is $15 a month. Explore agents
On the Gmail side, I have also written about what Gemini in Gmail still leaves to you, and there is a step-by-step guide to triaging an inbox with an AI agent.

5. Does Superhuman AI cost money?
Some of it is free: Grammarly Free includes 100 AI prompts a month, and the suite's Free plan has limited Go chat. Email Assistant starts at Pro, and Mail's Auto Drafts and Ask AI need a Business plan. Superhuman says usage-based pricing will come later, with notice first.
6. Is Grammarly part of Superhuman now?
Yes. Grammarly announced in July 2025 that it was acquiring the Superhuman email app, and on 29 October 2025 it renamed the company Superhuman. Grammarly is still the name of the writing product, and it still has its own plans page at grammarly.com.
7. Does Superhuman Pro include Grammarly Pro?
On yearly billing, yes: Pro at $144 a year includes Grammarly Pro, as of October 2026. On monthly billing, no. The $15 plan leaves it out, and adding it costs $15 more a member, which makes $30 a month.
8. Is there a Superhuman student discount?

10. I already pay for Superhuman Mail: should I switch to the suite?
If you pay for Mail on your own, you can convert to Superhuman Business at the same $33 or $40, as of October 2026, with a prorated refund for the unused Mail period, but Mail discounts do not carry over. Mail team admins get two different answers from Superhuman's help center, so confirm with Superhuman before cancelling anything.
