Free Plan Details
Grammarly's free plan is one of the best free writing tools available. It covers basic grammar, spelling, and punctuation corrections across all platforms where Grammarly is installed, including the browser extension, desktop app, and mobile keyboard. Free users get tone detection to understand how their writing comes across, and conciseness suggestions to tighten their prose. You also receive a limited number of GrammarlyGO AI prompts per month for generative writing assistance. The free plan works across Gmail, Google Docs, social media, and virtually any text field in your browser.
Hidden Costs & Limitations
- Massive annual vs. monthly price gap: Premium costs $30/month if billed monthly but just $12/month when billed annually ($144/year). This is one of the largest annual discounts in the SaaS space, making monthly billing very expensive.
- Plagiarism detection is Premium-only: The plagiarism checker, which scans against billions of web pages, is not available on the free plan.
- GrammarlyGO prompt limits: Free users get very limited GrammarlyGO prompts. Premium gets 1,000/month, and Business gets 1,000/member/month. Heavy AI users may still find these caps restrictive.
- Business plan minimum seats: The Business plan may require a minimum number of seats, making it impractical for very small teams.
- Style guides are Business-only: Brand style guides and custom tone profiles are exclusive to the Business plan. If you need brand consistency as an individual, you're out of luck.
- Integration depth varies: While Grammarly works in most text fields via its browser extension, deeper integrations with enterprise tools may require the Business plan.
- No API for individual plans: Programmatic access to Grammarly's capabilities is only available through enterprise-level agreements.
Which Plan Is Right for You?
- Free Plan: Perfect for students, casual writers, and anyone who wants basic grammar and spelling support. The free tier catches most common errors and is sufficient for everyday writing.
- Premium Plan ($12/mo annually): Best for professionals, freelance writers, bloggers, and anyone who writes regularly. The clarity suggestions, full-sentence rewrites, plagiarism detection, and expanded GrammarlyGO prompts are well worth $12/month on the annual plan.
- Business Plan ($15/member/mo annually): Ideal for teams and organizations that need consistent brand voice, style guides, admin controls, and analytics across their writing output. The per-member pricing makes it accessible for teams of all sizes.
The annual Premium plan at $12/month is Grammarly's best value for individuals. The difference between monthly ($30) and annual ($12) pricing is dramatic, so committing annually is strongly recommended if you plan to use it regularly.
