Grammarly AI

Grammarly sits in your browser and writing apps, flagging mistakes as you type—grammar, spelling, tone, clarity. It's useful if you write emails, documents, or social posts and want a second pair of eyes without leaving your workflow. The free tier covers basics; Premium ($12/month) adds tone detection and advanced rewrites. The catch: the free version is genuinely limited, and Premium's AI-powered suggestions sometimes miss context or feel prescriptive. It works best for high-stakes writing where accuracy matters more than speed.
