    About

    In practice. What you can do with Grammarly.

    Grammarly checks grammar, spelling and style across writing surfaces, with AI features on the paid Pro plan: full sentence rewrites, tone adjustment, and fluency suggestions aimed at non-native English writers, plus plagiarism and AI-generated-text detection.

    The free plan covers basic corrections and 100 AI prompts a month; Pro runs $12 a month for full rewriting and 2,000 prompts per member, though it wasn't confirmed whether that rate is monthly or annual billing. Team features (roles, groups, shared style guides) sit on Pro and Enterprise, with SSO, SCIM and data-loss prevention reserved for a custom Enterprise quote. It suits a consultant polishing client-facing English writing.

    Practical uses

    • Polish a client email or report for grammar, tone and clarity before sending,Real-time AI-assisted rewriting.
    • Check drafts for accidental plagiarism or AI-generated-text flags on the Pro plan before delivering client work.

    When it makes sense. Keep Grammarly, or challenge it?

    Keep if

    • You write in English regularly for clients and want AI-assisted rewriting plus plagiarism checks in one subscription.
    Grammarly becomes worthwhile when
    • You use it at least once a week
    • The monthly cost ($12) is small next to the time it saves you

    Challenge if

    • You need unlimited AI rewriting volume or SSO/compliance features without an Enterprise quote.
    Grammarly becomes too expensive when
    • You use it less than once a month
    • ChatGPT (free) already covers the essentials for occasional use

    Our verdict. What to know about Grammarly.

    Why this verdict

    Average

    Added value

    Pro adds full rewrites, tone, plagiarism and AI-generated-text detection for a moderate per-seat price, but whether $12 is monthly or annual billing wasn't confirmed, so value can't be fully judged.

    Simplicity

    Neutral score: time and skill needed to get a first useful result are not covered by the collected sources.

    Fit for purpose

    Grammar, style and tone checking works across surfaces, but AI-heavy workflows are capped even on Pro (2,000 prompts/member/month), which can push heavy users toward another AI tool.

    Performance

    Pro covers full rewriting, tone, plagiarism/AI detection and basic team features, while advanced security/compliance (SSO, SCIM, DLP, BYOK) requires a custom Enterprise quote.

    Reversibility

    Neutral score: export or portability of stored style guides and brand tones is not covered by the collected sources.
