Is Grammarly free to use?

Yes. The Free plan includes grammar and spelling corrections, tone detection, and 100 AI prompts per month with no credit card. Pro is $12 per month billed annually ($144 per year, or $30 month-to-month) and adds full-sentence rewrites, tone adjustment, unlimited personalized suggestions, plagiarism checks, AI-text detection, and 2,000 AI prompts per member per month.

Can Grammarly write marketing content for me?

Partly. Pro includes generative drafting for first drafts, outlines, and rewrites, with 2,000 AI prompts per member per month and unlimited prompts on Enterprise. It is not a campaign platform: it will not build content calendars, keyword briefs, or dozens of ad variants against a strategy, so pair it with a dedicated content generation tool if that is the job.

Which languages does Grammarly support?

Grammarly provides real-time writing support in English, Spanish, French, German, Portuguese, and Italian, plus in-line translation and paragraph-level rewrites in multiple languages for localized campaigns and support content.

How does Grammarly handle company data and security?

Grammarly states that it does not sell or monetize uploaded content, uses 256-bit AES for files at rest and SSL/TLS in transit, and complies with GDPR and CCPA. Enterprise adds SAML single sign-on, SCIM provisioning, custom roles, data-loss prevention, audit logs, and BYOK key management; those controls are not available on Pro.

Overview

Grammarly is the AI writing layer most marketing teams already have installed and rarely think about.

It checks grammar, spelling, and punctuation in real time, then goes further: clarity rewrites, tone detection, inclusive language, citation consistency, and full-sentence rewriting.

The Free plan covers the basics plus 100 AI prompts a month; Pro costs $12 per month billed annually ($144 per year, or $30 month-to-month) and lifts you to 2,000 AI prompts per member per month, unlimited personalized suggestions, and both plagiarism and AI-generated-text detection.

It works across browsers, desktop apps, email clients, and roughly a million sites and apps, so nobody has to change where they write. For marketing teams the differentiating feature is not proofreading, it is consistency.

Teams can upload a company style guide and add terms as they change, turn the company voice into a tone profile, and surface relevant internal information through Knowledge Share while people type.

Grammarly writes in English, Spanish, French, German, Portuguese, and Italian with in-line translation and paragraph-level rewrites, which matters for localized campaigns and support content.

Admins get member and budget management, roles and permissions, and dashboards that show where a team's writing is weakest; Enterprise adds SAML SSO, SCIM provisioning, audit logs, data-loss prevention, and BYOK encryption.

Grammarly's business pages state that it does not sell or monetize uploaded content, and that the product is now delivered through Superhuman Go with a proactive assistant and agents. The honest trade-off is scope.

Grammarly is an editing and writing-assistant layer, not a campaign generation platform: it will not build a content calendar, generate twenty ad variations against a brief, or optimize for search intent the way Jasper or an SEO content tool does, and its generative drafting is capped by prompt allowances (2,000 per member per month on Pro; unlimited on Enterprise, which is quoted on request).

Where it earns its place is the last mile - the draft you were going to ship anyway, made clearer, more consistent, and more on-brand.

Works wherever your team writes - browser, desktop apps, email clients, and a million-plus sites - with no workflow change
Style guide and tone profile are what actually keep distributed writers and freelancers on brand
Pro includes 2,000 AI prompts per member per month plus plagiarism and AI-text detection for $12/month billed annually
Writing support and in-line translation across six languages for localized campaigns

Cons

Generative prompts are capped on lower tiers; unlimited prompts require Enterprise, which is quoted on request

Data-loss prevention, BYOK, and audit APIs are Enterprise-only, so regulated teams cannot get them on Pro
Accepting suggestions wholesale can flatten a deliberately distinctive brand voice

We verified pricing on grammarly.com/plans: Free at $0 with 100 AI prompts per month, Pro at $12 per month billed annually ($144 per year, $30 month-to-month) with 2,000 prompts per member per month, and Enterprise by quote. The team features - a shared style guide, a company tone profile, and Knowledge Share - are what make it a marketing tool rather than a personal spell-checker.
