💡 Our Take
Choose Grammarly Enterprise for large teams that need SAML SSO, SCIM, roles and permissions, DLP, and support across business writing workflows. Choose ProWritingAid if you are an individual writer, author, or smaller editorial team looking for deeper manuscript-style writing analysis at a lower self-serve price point.
Grammarly Enterprise - Pros & Cons
Pros
- ✓Very broad writing coverage: Grammarly says it works across more than 1 million apps and websites, which makes it useful for email, documents, browser-based tools, and everyday business writing instead of only a dedicated editor.
- ✓Large adoption base: Grammarly reports being trusted by over 40 million people and 50,000 organizations, which gives enterprise buyers more confidence in product maturity and support expectations.
- ✓Clear upgrade path from free to enterprise: Free includes $0/month access with 100 AI prompts per month, Pro adds 2,000 AI prompts per member per month at $12/member/month billed annually, and Enterprise adds unlimited prompts per member.
- ✓Enterprise controls are stronger than a basic writing assistant: the Enterprise tier lists BYOK encryption, data loss prevention, custom roles and permissions, SAML SSO, SCIM, Feature Management Hub, and cost center visibility.
- ✓Useful for company-wide quality control because it supports tone, inclusive language, citation consistency, plagiarism checks, AI-generated text detection, and full-sentence rewrites in the same workflow.
- ✓Grammarly has a long operating history for an AI writing tool, founded in 2009, and has evolved into the Superhuman suite after acquiring Coda in late 2024 and Superhuman Mail in 2025.
Cons
- ✗Enterprise pricing is not published on the website, so buyers must contact sales and cannot quickly compare the total cost against self-serve tools.
- ✗Some advanced workflow value now depends on the broader Superhuman suite, which may be more product surface than teams want if they only need writing suggestions.
- ✗Pro has a documented limit of up to 149 seats, so larger teams must move into Enterprise or sales-assisted purchasing.
- ✗Enterprise domain controls require SAML single sign-on to be configured first, which adds setup work for administrators.
- ✗The privacy FAQ says Grammarly hosts data in AWS data centers in the US East region, which may be a constraint for organizations with strict regional data residency requirements.
ProWritingAid - Pros & Cons
Pros
- ✓Over 20 in-depth writing reports covering style, pacing, readability, clichés, redundancies, and more — far more analytical depth than most competitors
- ✓Excellent for fiction writers with genre-specific checks, dialogue tag analysis, pacing reports, and native Scrivener integration
- ✓Competitively priced with a lifetime purchase option that no major competitor offers, making it more affordable long-term
- ✓Broad integration support including Microsoft Word, Google Docs, Scrivener, Chrome, Firefox, Edge, and standalone desktop apps
- ✓AI Sparks feature provides contextual rephrasing suggestions and the contextual thesaurus accounts for sentence meaning when suggesting synonyms
Cons
- ✗Real-time editing performance is noticeably slower than Grammarly, particularly on longer documents where batch analysis is recommended instead
- ✗Can produce false positives on style suggestions, especially with creative or intentionally unconventional writing — requires writer judgment to filter
- ✗The free plan's 500-word limit makes it impractical for evaluating the tool on real documents before committing to a paid plan
- ✗User interface is functional but less polished than Grammarly's, with a steeper learning curve to navigate the numerous report types effectively
