Editor's note

Grammarly is useful at the end of a draft, not at the center of an argument. The tool should reward practical cleanup while warning students not to outsource disciplinary voice, evidence, or institutional integrity decisions to a browser extension.

Who it fits, where it fails

Best for

  • A final grammar, tone, and clarity pass on essays, emails, and public-facing copy
  • Teams that need style guides, brand tone, snippets, knowledge sharing, and usage analytics
  • Writers who want inline help across Google Docs, Word, Gmail, Outlook, Slack, Salesforce, PowerPoint, LinkedIn, Teams, Sheets, Zendesk, Jira, and other surfaces
  • People who benefit from revision suggestions but still keep ownership of voice and citations

Avoid if

  • You want offline-only editing with no cloud text processing
  • You purchased legacy Premium via App Store / Google Play and need guaranteed Pro migration now
  • You need 150+ seats without moving to a larger-organization/enterprise sales path
  • You treat plagiarism/AI-writing indicators as institutional proof without policy review

Strengths

  • Grammar/spelling
  • tone detection/adjustment
  • full-sentence rewrites
  • Free 100 AI prompts
  • Pro 2,000 AI prompts
  • plagiarism detection
  • style guides
  • brand tones
  • knowledge share
  • snippets
  • usage analytics
  • Pro 1–149 seats
  • Enterprise confidential mode
  • DLP
  • domain/app/client controls
  • MFA/custom security controls
  • Superhuman Go org controls

Weaknesses

  • Suggestions can flatten disciplinary voice
  • Cloud processing sends draft text to Grammarly/Superhuman systems
  • Sensitive-field exclusion is best-effort, not a guarantee
  • Enterprise confidential mode only covers supported surfaces/workflows
  • Plagiarism/AI signals are not institutional proof
  • Generative rewrites can alter meaning/citations/hedges

How it could improve

  • Summaries that flatten disagreement should preserve the debate, present multiple positions and mark where the literature is contested instead of smoothing it into one answer.
  • Institutional policy friction could be reduced with a local/on-prem deployment option, or at minimum with clear data-handling documentation that compliance teams can review without an NDA.
  • Confident tone masking uncertainty is a design flaw. Grammarly should surface confidence levels and explicitly flag when it's extrapolating beyond the evidence or when a claim is contested in the literature.
  • Institutional policy friction could be reduced with a local/on-prem deployment option, or at minimum with clear data-handling documentation that compliance teams can review without an NDA.
  • Citation accuracy needs investment. A citation-verification pass against Semantic Scholar or CrossRef before presenting a source would catch the worst fabrication errors.
  • Opportunity cost scores 49/100, the weakest dimension on this dossier. Addressing this would meaningfully raise the editorial fit.
  • Source grounding scores 52/100, the weakest dimension on this dossier. Addressing this would meaningfully raise the editorial fit.
  • Privacy posture scores 36/100, the weakest dimension on this dossier. Addressing this would meaningfully raise the editorial fit.
  • Evidence strength scores 52/100, the weakest dimension on this dossier. Addressing this would meaningfully raise the editorial fit.
  • Data portability scores 49/100, the weakest dimension on this dossier. Addressing this would meaningfully raise the editorial fit.

Privacy deep-dive · checked 2026-09-14

Grammarly (now under Superhuman) is cloud processed. Superhuman/Grammarly privacy and trust pages say they do not sell or monetize user content; they use collected information to train AI models unless the user turns off Product Improvement and Training in account settings. Users can view personal data, delete Grammarly Editor documents, or delete an account. Enterprise admins can enable confidential mode so Grammarly deactivates on Gmail confidential drafts and Word documents marked confidential. Still not offline; avoid sensitive drafts without policy approval.
