Grammarly

Grammarly is the AI writing assistant most people meet first. It checks your spelling, grammar, punctuation and tone as you type, and it works almost everywhere you write: in your browser, Microsoft Word, Google Docs, email and on your phone keyboard. The company says it is used by over 40 million people and 50,000 organizations, and it is now part of Superhuman.

This Grammarly review covers what it does in 2026, pricing in the US and India, the difference between the Free, Pro and Plus plans, and how it compares with alternatives like ProWritingAid and LanguageTool.

What Grammarly does

At its core, it underlines mistakes and suggests fixes in real time. On top of that, it now includes a set of AI features:

• Proofreading: grammar, spelling, punctuation, clarity and sentence structure.
• Tone suggestions: see how your writing sounds and adjust it to be more confident, friendly or formal.
• Full-sentence and paragraph rewrites: improve clarity and flow with one click.
• Generative AI prompts: draft, shorten or rephrase text from a prompt.
• Plagiarism and AI-text detection: check your work before you submit it.
• Humanizer and AI Detector agents: spot text that reads as AI-written and revise it.

Grammarly pricing (2026): US and India

Plans and prices differ by country:

• Free: $0 / ₹0. Spelling and grammar corrections, tone detection and 100 AI prompts a month.
• Pro (US and most countries): $12 per member per month on the US plans page, with a free trial. Adds full-sentence rewrites, tone adjustments, fluency help, unlimited personalized suggestions, plagiarism and AI-text detection, 2,000 AI prompts a month, plus team features such as a style guide, brand tone and analytics.
• Plus (India): ₹392 per member per month billed annually, or ₹1,000 billed monthly, paid with local payment methods. The company says Plus includes all of Pro’s advanced writing features plus basic customer support.

Is Grammarly free?

Yes. The free plan is enough for everyday spelling and grammar fixes and shows your tone, with 100 AI prompts a month. Its standalone AI Detector is also free and needs no sign-up. You only need Plus or Pro for full-sentence rewrites, plagiarism checks and heavier AI use.

Where Grammarly works

It runs as a browser extension, desktop apps for Windows and Mac, a web editor, and mobile keyboards for iPhone and Android. It also works inside Google Docs and Microsoft Office, so most people never need to copy and paste their writing into a separate tool.

Security and privacy

Grammarly holds a SOC 2 (Type 2) report covering security, privacy, availability and confidentiality. It says it never sells user content and does not allow third parties to train their models on it. It does use writing to improve its own products, and it offers product improvement and training controls in your account settings. Business users get extra controls, such as data loss prevention and BYOK encryption, on Enterprise.

Grammarly vs alternatives

• ProWritingAid gives deeper style reports and suits long-form and fiction writers.
• LanguageTool checks 30+ languages and is a better fit if you write in more than English.
• QuillBot is stronger at paraphrasing and summarizing.

Grammarly review verdict: who it is for

It suits students writing essays, professionals writing emails and reports, bloggers and anyone who writes in English as a second language. The free plan covers the basics; Pro (Plus in India) is worth it if you write every day and want rewrites, tone help and plagiarism checks.
