Grammarly’s generative AI features are not sold as a separate product. They are entitlements of the Free, Premium, Pro, Enterprise and Education plans, each with a monthly allowance that the vendor counts in prompts.[1] The Terms of Service tell users that, depending on the plan, they may have limits on the generative AI features.[3] See Generative AI prompt.
Allowance by plan
| Plan | Monthly generative AI prompts | Source |
|---|---|---|
| Free | 100 | [1] |
| Premium (App Store and Google Play) | 1,000 | [2] |
| Pro | 2,000 per member | [1][2] |
| Enterprise | Unlimited per member | [1] |
The Superhuman suite page uses relative terms: “Limited prompts” on Free, “More prompts” on Pro, and “Most prompts” on Business and Enterprise for on-demand AI composition, and lists paragraph translation, paragraph rewrites and the Proofreader agent as limited on Free and unlimited on paid plans.[10] No numeric count for the suite Business plan is shown on that page.
The prompt allowance is per member, so on team plans the effective allowance scales with seat count: a 10-seat Pro subscription has 20,000 monthly prompts across members, though the sources do not say that prompts pool between members. That inference is commentary; the documents state only that Pro gives “2,000 prompts / member / month”.[1]
What counts as use
The Support Center describes two surfaces: on-demand generative AI assistance in the browser extension for Chrome and Edge, the classic Grammarly Editor and the Windows and Mac apps, and the Go proactive assistant and agents in the browser extension and in docs, the new AI writing surface.[8] The documents reviewed do not publish a definition of a prompt or state which actions deduct from the allowance; the plan page and the Pro article give only the monthly numbers. A licence manager who needs to verify consumption would need to ask Superhuman how prompts are counted.
Terms that apply to AI use
- Ownership. Inputs and Outputs are the user’s User Content, but other users may receive similar outputs, and outputs generated for others are not the user’s.[3]
- Usage limits and add-ons. If a user exceeds the plan’s usage limits, Superhuman may require additional capacity or units. Any capacity bought is tied to the then-current subscription, is not transferable to another account and is not refunded on expiry or termination.[3]
- Restrictions. Generative AI features must not infringe rights or be used to develop foundation or large language models that compete with the Services.[3]
- Outputs disclaimer. Superhuman makes no representation about the accuracy or suitability of outputs, which are used at the customer’s risk.[3]
- Enterprise data. Under the Customer Business Agreement, Superhuman and its Affiliates will not use Customer Data to train generative AI models without the customer’s prior written consent.[4] The Terms of Service instead license User Content to Superhuman for limited purposes including improving and developing services, so the position differs by contract.[3]
- Beta. Features labelled alpha, beta or early access are provided without a support obligation and without liability.[3]
Document and word check limits
The Acceptable Use Policy sets maximum checks: no more than 300 documents within Docs or 150,000 words across all Superhuman services in any 30-day period, and no more than 100 documents within Docs or 50,000 words in any 24-hour period. For members of Superhuman Business and Superhuman for Education enterprise accounts, the limits apply to each end user individually.[5] The same policy bars abusing billing or pricing mechanics, including free accounts, trials, betas and account credits.[5] See Document and word check limit.
Trial and limit wording on the suite plans
On the Superhuman suite page, several AI features are described by tier rather than by number: AI chat and inline agent suggestions show “Limited chat access” or a “limited free trial of full chat” on Free, Pro, Business and Enterprise entries, usage credits are marked “Limited trial”, and usage tracking is marked “Coming soon”. Custom agents are described as limited, expanded or full by plan, and model training is shown as opt out on Free, Pro and Business and off by default on Enterprise.[10] Because these entries describe a changing product and carry no dates, they are treated here as descriptive and not as contractual allowances.
Education
The Education page describes generative AI for students as optional, for brainstorming and outlining, and says writing suggestions come with explanations; it offers no prompt numbers, which an institution would obtain in its quote.[12]
Admin controls
Admins on Pro, Plus, Business, Enterprise and Education plans can open a Feature access page to switch features on or off for the whole subscription or for groups, including the AI assistant, strategic suggestions, paragraph-level rewrites, Authorship, Knowledge Share, personal snippets and individual usage analytics.[6] Access to the Grammarly Editor and to docs with agents is configurable only on Business, Enterprise and Education plans purchased through the Sales team.[6] In docs, all agents are available by default once docs are enabled, and admins on Sales-purchased plans can turn agents such as Paraphraser, Humanizer, Reader Reactions, AI Grader, Citation Finder, AI Detector and Plagiarism Checker on or off for all members or specific groups.[7]
Superhuman Go and the Enterprise licence
Enterprise Grammarly is described as available through Superhuman Go, which combines Grammarly with agents and connectors.[11] The Support Center says the Go Enterprise License Agreement gives an organization access to Superhuman Go and Grammarly, and that admins invite members, see the number of available seats, create groups and manage roles from the Superhuman admin settings.[9] Pre-existing Grammarly group lists are migrated into the Superhuman account when members join.[9]
Reading the numbers
Three points follow from the documents. First, the numeric allowances come from the pricing page and the Pro article, not from the Terms of Service, which refer only generally to plan limits and to extra capacity the vendor may require. Second, the enterprise Customer Business Agreement states no prompt quantity, so the Order is the document that fixes it for those customers.[4] Third, the pricing page describes Enterprise as unlimited per member, which does not remove the Acceptable Use Policy’s document and word check limits.[1][5]
Out of scope
This article does not cover the privacy practices around AI processing, the security assessments Grammarly publishes, or third-party agents and connectors purchased through the Superhuman Marketplace, which carry their own terms.[3]
