Summary

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.

Bottom line: *Use this if email and document accuracy matter; skip it if you write fast and loose or rarely proofread.*

Many writers miss grammar, spelling, tone, and clarity problems when they draft emails, documents, or social posts and lack an extra set of eyes inside their normal workflow.

How it works

Grammarly sits in your browser and writing apps, flagging mistakes as you type. The vendor states it covers grammar, spelling, tone, and clarity. It integrates with popular platforms and is available on Web, iOS, and via API, with connections to Slack, Zapier, and Microsoft Teams.

Pricing and limits

The tool uses a freemium model at $12 per month for Premium. The free tier covers spelling and grammar checks plus tone display and 100 AI prompts per month. Advanced tone detection and rewrites require the paid plan.

Strengths and trade-offs

Real-time feedback, grammar and spelling corrections, and broad platform integration are listed as pros. Cons include a limited free tier and the need for a subscription to unlock advanced features. The docs describe cases where AI suggestions miss context or feel prescriptive. It suits proofreading written content, writing emails and messages, and editing documents.

Who it is for / who should skip it

Use it if you need steady grammar and style support across apps and can pay for Premium when the free tier runs out. Skip it if you want unlimited free AI prompts or need suggestions that always match exact context.
