What is Grammarly?
Grammarly has evolved from a grammar checker into a full AI writing partner. Alongside its famously reliable spelling, grammar and tone corrections, it now offers generative drafting and rewriting, AI detection, plagiarism checking and automatic citations, plus specialised AI agents such as Proofreader, Humanizer, Citation Finder and AI Grader. Everything runs where you already write: the browser extension, desktop apps, mobile keyboards and its own AI-powered document surface.
The Slick Media verdict
The default AI writing partner. Free covers everyday corrections; Pro earns its keep with rewrites, plagiarism and AI detection. Use the suggestions as prompts rather than orders and it lifts everything you publish.
AI summary
Grammarly checks spelling, grammar, clarity and tone wherever you write, in the browser, desktop apps and mobile keyboards, and now generates and rewrites text with generative AI while enforcing a shared style guide across a team. The default writing safety net. Use the suggestions as prompts rather than orders and it lifts everything your team publishes.
Why choose Grammarly
Choose Grammarly as an always-on AI writing partner: it catches mistakes and tone problems before your readers do, then helps you draft, rewrite, cite and check originality without leaving the apps you already use.
