Grammarly

Grammarly is a writing assistant founded in 2009, now headquartered in San Francisco with deep engineering roots in Kyiv. It began as a grammar and spelling checker and grew into a full communication tool that works across browsers, desktop apps, Microsoft Office, and Google Docs, reaching tens of millions of daily users.

The Free tier handles spelling, grammar, and basic punctuation. Grammarly Pro adds clarity and tone rewrites, vocabulary suggestions, plagiarism detection, and generative AI prompts, while Grammarly Business layers on style guides, brand tones, analytics, and centralized billing for teams. There are also dedicated plans for education institutions.

Because it is subscription software, savings concentrate on annual billing, which is dramatically cheaper per month than paying monthly, alongside team pricing that lowers the per-seat rate and periodic seasonal promotions. Students often access it through their university. The verified Grammarly coupon codes and deals on this page focus on those routes so you can write well for less.
