Grammarly

What it does

Grammarly is an AI tool for checking grammar and spelling, checking for plagiarism and writing emails. It has a free plan, and paid plans start at $12 per month.

Grammarly is an AI writing assistant that reviews text as people type, flagging grammar, spelling, punctuation, clarity, and tone issues and offering inline revisions. It can rewrite full sentences or paragraphs, suggest a different tone, paraphrase passages, check for plagiarism, detect AI-generated text, and make AI-assisted writing sound more natural. A browser-based document editor called Docs adds writing agents, citation help, and reader-reaction feedback for longer drafts. It is built for individuals, teams, and organizations that write email, reports, proposals, school papers, and other documents. Grammarly works in web browsers and on Windows, Mac, Android, and iOS, and its pages list use inside Gmail, Google Docs, Microsoft Word, Slack, and LinkedIn. Team plans add shared style guides, brand tones, reusable snippets, and analytics so groups can keep wording consistent. The free plan costs $0 and covers basic proofreading, tone viewing, and a limited monthly allowance for generative AI prompts. Pro starts at $12 per member per month billed annually, and a Pro trial is available; it adds full-sentence rewrites, tone adjustment, plagiarism and AI detection, and a larger prompt allowance. Enterprise adds unlimited prompts, admin controls, dedicated support, and other organization features.
