Grammarly

Grammarly is an AI writing partner that works inside the applications people already write in: email, documents, browser tabs, messaging and productivity tools. It corrects mistakes, rewrites full sentences for clarity, adjusts tone without erasing the writer's voice, and shows how a reader is likely to receive a message so it is understood the first time. It serves students, professionals and organizations that want consistent, credible writing across every channel. Beyond core suggestions, Grammarly offers specialized agents, including a Humanizer, an AI Detector, a Resume Builder, a Citation Finder and an AI Grader, and generates text from prompts. The Pro tier adds plagiarism and AI generated text detection, fluency support for English writers and unlimited personalized suggestions. Enterprise adds proactive AI that works everywhere, BYOK encryption, custom roles and permissions, data loss prevention, cost center visibility and dedicated support. Grammarly states that it does not sell or monetize user content or provide it for advertising. Pricing is published in US dollars. Free costs $0 per month and includes mistake free writing, tone detection and 100 AI prompts. Pro costs $12 per month, includes 2,000 AI prompts, and offers a free trial with an email reminder two days before it ends. Enterprise pricing is available through sales. Grammarly is now part of Superhuman, which positions the combined product as extending the same writing assistance to every doc, tab and tool a person uses.
