Grammarly Pricing 2026: Is Free Enough, and What Does Pro Actually Cost?

TL;DR: Grammarly’s free plan covers basic grammar, spelling, and tone checks, and that’s genuinely enough for a lot of casual use. Pro adds full-sentence rewrites, plagiarism detection, and much higher AI usage limits — but the “$12/month” shown on the pricing page is an annual-averaged rate, not what you pay if you bill monthly. If you bill monthly, it’s actually $30/month. That gap is worth knowing before you click upgrade.

Why Listen to Me on This

I’ve used Grammarly’s free version for a while now, mainly to proofread finished writing — reports, emails, that kind of thing — and especially as a second check when writing in a language that isn’t my first. I’ve never paid for Pro, so this isn’t a “review from the inside” of the paid tiers. It’s the opposite: an honest look at what free actually covers, whether Pro’s extra features are worth paying for based on what I know I’d use, and a pricing detail that’s easy to miss if you’re just skimming the plans page.

Grammarly Free: What You Actually Get

The free plan checks spelling, grammar, and punctuation, and shows you the tone of what you’ve written. It also includes 100 AI prompts a month for things like rewriting a sentence or generating text. For catching typos and obvious mistakes before sending an email or submitting a report, this has been enough for my use case.

What it doesn’t do: full-sentence rewrites, plagiarism/AI-content detection, or the deeper “make this more formal” style adjustments — those are gated behind Pro.

Grammarly Pro: What Changes

Pro adds a meaningful jump in capability, not just a limit increase:

• Full-sentence rewrites (not just word-level suggestions)
• Tone adjustment on request
• Plagiarism and AI-generated text detection
• 2,000 AI prompts a month instead of 100
• Unlimited personalized suggestions
• Team features — account roles, a shared style guide, one brand tone, a team analytics dashboard

If you’re the kind of user who wants Grammarly to actively rewrite passages rather than just flag issues, this is the tier that does that. The free plan nudges; Pro rewrites.

The Pricing Detail Most People Miss

Here’s the part worth slowing down for. Grammarly’s plans page advertises Pro at $12/month — but that’s the annual-averaged rate. You’re actually billed $144 upfront for the year, not $12 charged monthly.

If you’d rather pay month to month with no annual commitment, the real price is $30/month ($360/year). That’s a $216/year difference for the exact same plan, just depending on how you’re billed. Neither option is hidden or dishonest, but the $12 figure is the one that gets remembered, and it’s not the number you’ll see on a monthly statement unless you commit to the year upfront.

If you’re going to upgrade, decide up front whether you want the annual price or the flexibility to cancel anytime — because those are two different price points, not one.

Is Free Enough?

Based on what I actually use Grammarly for — proofreading finished documents and catching mistakes before sending — free has covered it. If your use case is similar (occasional proofreading, not high-volume writing or team collaboration), I’d start on free and only upgrade once you hit a specific limit, like wanting plagiarism checks or running out of AI prompts, rather than upgrading preemptively.

Pro starts to make more sense if you’re rewriting drafts frequently, need plagiarism/AI-detection for academic or professional reasons, or you’re managing a small team that needs a shared style guide.

Grammarly Business and Enterprise (Briefly)

Above Pro, Grammarly also offers a team-oriented tier — bundled with Superhuman Mail in 2026 — priced per member per month, and a custom-priced Enterprise tier with SSO, audit logs, and admin controls for larger organizations. Neither is relevant for individual or small-scale use, so I won’t go deep on them here — if you’re evaluating those tiers, you’re likely already talking to Grammarly’s sales team directly.

Pricing at a Glance (2026)

Business	From ~$33–40/member/mo	Small teams needing shared style guides
Enterprise	Custom	Larger orgs needing SSO/admin controls

FAQ

Is Grammarly actually free, or is it a limited trial? The free plan doesn’t expire — there’s no trial clock. It’s a genuinely permanent tier, just with fewer features than Pro.

Is the $12/month price real? Yes, but only if you pay for the full year upfront ($144 total). Paying month to month is $30/month instead.

Final Verdict

Free is a legitimate long-term option if your needs are light — I’ve used it that way for a while now. Pro is worth it once you specifically need rewrites, plagiarism detection, or higher AI limits, not just because the $12/month number looks appealing. Know which billing option you’re actually choosing before you upgrade.
