Maintain Brand Voice in All Copy
Marketing teams use Grammarly to ensure consistent brand messaging across campaigns, social media, and website content. It helps refine ad copy and blog posts for clarity and impact.
AI writing assistant that checks grammar, spelling, clarity, tone, and style in real time across browsers, documents, email, and desktop apps.
Grammarly is the proofreading and writing assistant that runs as a browser extension, desktop overlay and mobile keyboard — anywhere you type. The 2024-25 product expansion bolted a generative AI assistant on top, so it now handles drafting, rewriting and tone shifts alongside the original grammar engine.
Install the extensions and apps, log in once, and Grammarly runs everywhere — Gmail, Outlook, Google Docs, Slack, LinkedIn, Notion, Word. Free covers spelling, grammar and basic punctuation. Premium adds clarity rewrites, tone detection, formality adjustments, plagiarism check and the AI assistant for drafting and rewriting.
The AI assistant drafts emails from prompts, rewrites for length, shortens, lengthens, makes more direct or more diplomatic. Not a Jasper-grade content generator but the right tool for "rewrite this email more politely". Business and Enterprise tiers add brand voice, style guides and admin controls.
Free covers grammar, spelling and punctuation. Premium $12-30/month depending on annual vs monthly (the $12 marketing claim is the annual rate; monthly direct is closer to $30). Business $15/user/month minimum 3 seats with brand voice and style guides. Enterprise custom-priced. NachoNacho applies a discount to Premium and Business via the marketplace.
Caveat: AI generator is capped at 100 prompts/month on Premium. Heavy AI users hit the cap and either upgrade to Business or use ChatGPT for the heavy work.
