Our verdict

Superhuman suits people who already use Grammarly and want an AI assistant across apps, collaborative docs or email in one subscription. The trade-offs: Mail only arrives with the Business plan at 33 USD per member per month billed annually, content may be used for AI training unless you opt out, and user ratings vary widely by venue.

Best for: People who write a lot of English emails and documents and want grammar and tone suggestions in the browser.

Skip it if: Users who only need a simple free tool, or who do not want content sent to a cloud service for AI processing.

Pros

  • The Free plan already includes Grammarly, Docs and Go, so you can try before paying.
  • Per the company's announcement, Go runs in the Chrome and Edge extensions and connects to 100+ apps; the homepage advertises a library of 100+ pre-built agents.
  • The company documents an account setting to switch off use of content for AI training.

Cons

  • Mail is not in Free or Pro; it starts at Business.
  • AI training is opt-out: content may be used to train models until you turn it off.
All pros and cons · Who is it for?

Cons

  • Mac App Store reviewers complain that it pops up in too many places and drains resources in the background; the Chrome extension scores 3.9/5 and Trustpilot 3.1/5.
  • Per Wikipedia, in March 2026 the Expert Review feature drew criticism for simulating advice from real authors without their permission; the company dropped it the same day a class action was filed.

Best for

  • Teams that want an editor, collaborative docs, an inbox and an AI assistant under one contract.

Problems it solves

Experience & key features

What is Superhuman?

In late October 2025, Grammarly renamed the company Superhuman and brought Grammarly, Coda and Superhuman Mail under one brand, adding a new assistant called Superhuman Go. The company's post says the suite serves more than 40 million daily users, 50,000 organizations and 3,000 educational institutions. Grammarly is still the best-known part, founded in 2009; per Wikipedia, Coda was acquired in December 2024 and Superhuman Mail in July 2025.

Main components

Per the homepage, Go brings agents into the tools you already use, with a library of 100+ pre-built agents from Superhuman and partners. Mail has Auto Drafts (drafts built from your inbox, calendar and the web), Split Inbox and availability sharing; Docs is a collaborative workspace with Docs AI and Docs MCP. The October 2025 announcement says Go runs in the Chrome and Edge extensions, with Mac and Windows versions coming soon; the Chrome Web Store listing still describes Go as an opt-in beta. Grammarly also ships a Mac app, an Android app and browser extensions.

Pricing and value

The pricing page lists four plans: Free (0), Pro at 15 per member per month (12 billed annually), Business at 40 (33 billed annually) and Enterprise by quote. The page shows only a $ sign without naming the currency, so the USD figures here are AppDuo's reading of a US-facing page. Mail is only available from Business. The page says nothing about refunds or a paid-plan trial. Note that buying inside the Grammarly Mac app costs much more: 29.99 USD a month or 139.99 USD a year on the Mac App Store.

More analysis

Who it fits, and alternatives

Superhuman fits frequent English writers and teams wanting one contract for writing, docs and email. If you only need a note-taking editor, Notion or the Google and Microsoft suites may be enough; for rewriting and grammar checks alone, QuillBot is another option. Note the spread in ratings: 4.2/5 on Google Play, 3.9/5 on the Chrome Web Store and 3.1/5 on Trustpilot.

Cancellation & refunds

The pricing page says nothing about refunds or a paid-plan trial; terms sit in the Customer Business Agreement it links to, which AppDuo has not reviewed. The page shows a $ sign without naming the currency.

Privacy

The privacy policy (effective 6 July 2026) names Superhuman Platform Inc. as the data controller. The company may use information it collects, including your content, to train its AI models. The Trust page frames this as an opt-out: to keep your content out, turn off Product Improvement and Training in account settings. Its websites use advertising partners' cookies, which some privacy laws treat as "sharing" or "selling"; the company says user content is not given to these partners and offers a "Your Privacy Choices" opt-out. The Trust page says user content is not sold, annual security certifications are maintained and third-party firms run penetration tests, without naming the certifications. For organization-managed accounts, data is handled under the contract with that organization. Wikipedia records a 2018 browser-extension vulnerability (CVE-2018-6654).

Frequently asked questions

Is Superhuman the same as Grammarly?

Grammarly renamed the company Superhuman in October 2025. Grammarly remains a product in the Superhuman suite alongside Coda (Docs), Superhuman Mail and Go. The company says existing customers see no change to the products they use, only new capabilities.

Is Superhuman free?

There is a Free plan with Grammarly, Docs and Go, limited on rewrites and automations. Unlimited rewrites and translation need Pro; Mail needs Business.

Is my content used to train AI?

It can be. The privacy policy allows content to be used for model training, and the Trust page describes it as an opt-out: you turn off Product Improvement and Training in account settings. Organization-managed accounts follow the organization's contract.

Which languages does Superhuman support?

The Mac App Store lists the app's interface in English only. For content, the pricing page says Pro translates paragraphs into 17 languages (the plan blurb says 15+) without listing them.

Scores

Ease of use
7.8
Why this score

Suggestions appear inside familiar browsers and apps and a Free plan gets you started. The suite now has many parts (Go, Docs, Mail, Agents), which makes choosing a plan more confusing. The app interface is English-only.

Features
8.0
Why this score

Broad scope: writing, collaborative docs, email, a multi-app assistant, an agent library and CRM views. But Go only launched in late 2025, is still an opt-in beta in the Chrome extension, and Mac and Windows versions were only promised as coming soon.

Value for money
7.2
Why this score

Free is generous enough to try and Pro at 12 USD a month annually is reasonable. But Mail requires Business at 33 USD a month annually, well above writing-only tools.

Performance
6.6
Why this score

No independent performance benchmarks were found. A few Mac App Store reviewers (too few for a rating to display) mention resource use, and the Chrome extension holds 3.9/5 across 43.2K ratings.

Support
6.5
Why this score

Only Enterprise's dedicated support team could be confirmed. The pricing comparison mentions a Help Center, webinars, live chat and priority support without clearly mapping them to plans, so the score is middling.

Privacy & security
6.4
Why this score

Positives: content is not sold or given to ad partners, and there is an AI-training opt-out. Negatives: training is opt-out rather than opt-in, the websites use ad cookies some laws treat as selling, certifications are not named, and a 2018 extension vulnerability. Scored below Notion (6.8) because AI training must be switched off manually.
