Frequently Asked Questions

What is Grammarly?

Grammarly is the most widely used AI writing assistant, with tens of millions of daily users. It checks grammar, spelling, clarity, and tone in real time across browsers, documents, and email, and through its generative layer it now also rewrites sentences, adjusts tone, and drafts text from prompts.

How much does Grammarly cost?

Grammarly has a free plan covering core grammar and spelling checks. As of 2026 the paid Pro plan starts around 12 dollars a month on an annual commitment and roughly 30 dollars a month if paid monthly, with custom Enterprise pricing for larger organizations. The free tier is enough for basic everyday correction.

What is Grammarly best for?

Grammarly is best for editing and polishing writing you have already drafted. Its strength is catching errors, improving clarity, and adjusting tone everywhere you type, from email to docs. For generating long-form articles or marketing campaigns from scratch, a dedicated content generator is a better primary tool.

Does Grammarly write content for you?

Yes, to a degree. Beyond correction, Grammarly's generative AI can draft text from a prompt, rewrite passages, and shift tone. Its core identity is still an editing and clarity assistant though, so it complements a content generator rather than fully replacing one for heavy long-form production.
