What is Grammarly?
Grammarly helps you fix spelling and grammar, adjust tone and rewrite sentences while you write. A free plan covers basic corrections and limited AI prompts; Pro adds full-sentence rewrites, plagiarism and AI detection, and more prompts. Enterprise is sold for larger organizations through Superhuman Go. Grammarly says it does not sell user content or let third-party providers train on it.
What you use Grammarly for
Grammarly is a writing assistant that sits in the browser, desktop and many text fields. The homepage highlights paragraph rewrites, tone suggestions, proofreading, a Humanizer agent and an AI Detector agent. You keep drafting in your usual app while Grammarly suggests fixes and clearer wording.
On paid plans the comparison table adds full-sentence rewrites, adjusting tone, writing fluently in English, inclusive language, consistent citations, AI-generated text detection and accidental plagiarism checks. Team and Enterprise rows add style guides, brand tones, knowledge sharing and analytics. Grammarly states it does not sell or monetize user content for ads and does not allow third-party providers to train on that content.
Plans and what they include
The plans page lists Free at $0 per month with write-without-mistakes, see-your-writing-tone and 100 AI prompts per month. Pro is shown at $12 USD per month when yearly billing is selected, with a try-for-$0 trial and an email reminder two days before it ends. Pro includes everything in Free plus rewrite full sentences, adjust tone, write fluently in English, unlimited personalized suggestions, detect plagiarism and AI-generated text, and 2,000 AI prompts per member per month. Enterprise is contact sales, described as available through Superhuman Go, with unlimited prompts per member and organization controls such as SSO and data loss prevention. Monthly versus yearly list prices can differ; confirm the amount at checkout for your region.
A first workflow to try
Create a Free account, open a short email or paragraph you already wrote, and accept only the grammar fixes first. Then try one tone suggestion and one rewrite on the same text and compare whether the voice still sounds like you. If you need plagiarism or AI detection, start the Pro trial from the plans page and run those checks on a draft you are allowed to upload. Cancel before the reminder date if you do not want to keep Pro. AppFor.ai has not measured rewrite quality; follow Grammarly's own UI.
