Grammarly Premium ($12–$30/month depending on plan and billing term) is worth it if you write professionally every day — emails, reports, or client-facing content — and want tone and clarity suggestions beyond basic grammar. Casual users are better served by the free tier or free alternatives like Microsoft Editor or LanguageTool, which catch the same core errors without a subscription.
Grammarly has become the default grammar checker for millions of people, largely because it’s genuinely good at catching the errors spell-check misses — subject-verb agreement, comma splices, awkward phrasing, and tone mismatches. But the free version only goes so far, and the Premium subscription isn’t cheap once you factor in the jump from monthly to annual pricing tiers.
This review breaks down exactly what you get at each Grammarly tier, then compares it honestly against ProWritingAid, the free Microsoft Editor, and LanguageTool — three alternatives that cover a surprising amount of the same ground for less money or none at all.
What Grammarly Free Actually Covers
Grammarly’s free tier checks spelling, basic grammar, and punctuation across the browser extension, desktop app, and mobile keyboard. It’s genuinely useful and more accurate than the built-in spell-checkers in most browsers and word processors. For casual writing — emails, social posts, messages — free Grammarly alone is often enough.
What’s missing from free: tone detection, full-sentence rewrites, clarity and conciseness suggestions, plagiarism detection, and vocabulary enhancement. These are gated behind Premium, and they’re where Grammarly’s actual value proposition lives.
What You Get With Grammarly Premium
Grammarly Premium ($12–$30/month)
Premium adds full-sentence rewrite suggestions, tone adjustment (so you can check whether an email reads as “confident” or “friendly” before you send it), advanced clarity and conciseness edits, a plagiarism checker with citation suggestions, and vocabulary enhancement for word choice. The generative AI features let you draft, rewrite, or summarize text directly inside the editor.
The pricing is the real friction point: paying monthly runs close to $30/month, while committing to an annual plan drops the effective monthly cost to around $12. For freelance writers, marketers, students writing theses, or anyone sending client-facing emails daily, that’s a reasonable trade. For occasional writers, it’s expensive for what amounts to a nicer spell-checker.
Grammarly Alternatives Worth Considering
ProWritingAid — Best for Long-Form Writers
ProWritingAid leans harder into style analysis than Grammarly — it flags overused words, repetitive sentence structure, pacing issues, and readability scores, which makes it a favorite among novelists and long-form content writers. It integrates with Scrivener and Google Docs and offers a one-time lifetime purchase option in addition to subscriptions, which Grammarly doesn’t offer.
Its real-time grammar checking is slightly less polished than Grammarly’s, and the interface has a steeper learning curve with its dozens of report types. But for anyone writing books, long articles, or scripts, its deeper style feedback often beats Grammarly’s more surface-level suggestions.
Microsoft Editor — Best Free Option for Office Users
Microsoft Editor is built into Word, Outlook, and Microsoft 365, and it’s free for basic grammar and spelling checks, with a Premium tier bundled into Microsoft 365 subscriptions that adds clarity, conciseness, and formality suggestions — genuinely comparable to Grammarly Premium’s core writing suggestions.
If you already pay for Microsoft 365 for Word or Outlook, Editor’s Premium features are essentially free on top of a subscription you already have. The catch is coverage — it works well inside Microsoft apps and the Edge browser, but its extension for Chrome and other browsers is noticeably less capable than Grammarly’s.
LanguageTool — Best Free Multilingual Option
LanguageTool checks grammar, spelling, and style across more than 30 languages, which makes it the strongest option here for non-native English writers or anyone who writes in multiple languages regularly. The free tier is genuinely generous, covering core grammar and style checks in a browser extension and desktop app.
Its premium tier (roughly comparable in price to Grammarly Premium) adds advanced style rewrites and a higher daily check limit. The suggestion quality in English is good but not quite as polished as Grammarly’s tone detection — where LanguageTool wins outright is multilingual support Grammarly simply doesn’t offer.

Frequently Asked Questions
Is Grammarly free good enough for everyday use?
For casual writing — emails, texts, social posts — yes, free Grammarly catches most spelling and grammar errors effectively. It’s when you need tone checking, full rewrites, or plagiarism detection that Premium becomes necessary.
Is Grammarly Premium worth it for students?
It depends on the workload. Students writing frequent essays or a thesis benefit from the clarity and plagiarism-checking features. Students with lighter writing loads are usually fine with Microsoft Editor (if they already use Word) or LanguageTool’s free tier.
Does Grammarly work with Google Docs and Gmail?
Yes, Grammarly’s browser extension integrates directly with Google Docs, Gmail, and most web-based text fields, which is one reason it has broader day-to-day coverage than some competitors that are limited to specific apps.
Final Thoughts: Grammarly Premium earns its price for people who write professionally every day and want tone and clarity feedback baked into their workflow. If your budget is tighter or your writing is more occasional, Microsoft Editor (if you’re already in the Microsoft ecosystem) or LanguageTool’s free tier will cover most of what you actually need without a subscription.
