Grammarly — The most widely used AI writing assistant, checking grammar, spelling, tone, and clarity in almost every app you type in, now with generative AI drafting.
Verdict at a glance
Overall rating: 4/5 ★★★★☆
Standout: Unmatched reach — the browser extension and desktop apps put real-time writing feedback in virtually every text field on the web.
Watch out: The generative AI drafting is solid but trails Claude and ChatGPT for quality, and monthly AI-prompt limits apply on every tier.
A near-essential everyday writing aid for anyone who wants cleaner, clearer writing without switching tools. Treat the generative features as a convenient bonus rather than the reason to buy — the correction engine and ubiquity are the real value.

Overview
Grammarly is an AI writing assistant that reviews grammar, spelling, punctuation, tone, and clarity as you type. It works through a browser extension, native desktop apps for Mac and Windows, mobile keyboards, and direct integrations with tools like Microsoft Word and Google Docs. Its defining strength is reach: because the extension operates in nearly every text field on the web — Gmail, LinkedIn, Slack, Notion, and thousands more — you rarely have to copy text into a separate tool to get feedback.
Beyond corrections, Grammarly’s generative AI (GrammarlyGO) can draft content from a prompt, rewrite for a chosen tone, shorten or expand text, and summarize long threads. In 2026 the product consolidated its old Premium and Business tiers into a single Pro plan that scales from individuals to teams of up to 149 seats, with an AI-prompt allowance on each tier. The drafting quality is adequate for quick first passes but is best paired with human editing; for high-quality long-form generation, dedicated assistants still win.

Recent changes
Grammarly consolidated its former Premium and Business plans into a single Pro tier (individuals through teams of up to 149 seats), with tiered monthly AI-prompt allowances (~100 on Free, ~2,000 on Pro). GrammarlyGO generative features — drafting, tone rewriting, and thread summaries — continue to expand across supported apps.
Frequently asked questions
Is Grammarly free?
Yes. The Free plan covers grammar, spelling, punctuation, and basic tone checks plus roughly 100 AI prompts a month; full rewrites, tone/clarity coaching, and heavier generative AI use require Pro at $12/member/mo (annual).
Why does Grammarly cap AI prompts even on paid plans?
Every tier — including Pro — meters generative AI usage with a monthly prompt allowance (about 2,000/mo on Pro), so very heavy AI drafting users can hit limits that a flat-fee tool like ChatGPT or Claude wouldn’t impose.
Is Grammarly better than ChatGPT or Claude for writing?
Grammarly wins on ubiquity and real-time correction inside virtually any text field you already use; ChatGPT and Claude produce noticeably stronger long-form generative drafts — most people use Grammarly for editing and a dedicated AI assistant for first-draft generation.
What is Grammarly’s rating on G2 and Capterra?
As of 2026-08-06, Grammarly holds 4.7/5 on G2 (14,049 reviews) and 4.7/5 on Capterra (7,218 reviews, listed as Grammarly Business). See the ratings table above for links to the live pages.
