In-Depth Review
Grammarly Review: The Writing Assistant Everyone Needs
Grammarly is the most widely adopted AI writing tool, and for good reason – it works everywhere. The browser extension checks your writing in Google Docs, email, social media, and any web form. Beyond basic grammar and spelling, Grammarly’s AI now offers tone adjustments, full-sentence rewrites, and generative AI features.
The free plan is genuinely useful, catching basic errors and offering clarity improvements. Premium at $12/mo (billed annually) adds advanced suggestions for tone, formality, and style. The Business plan adds brand tones and style guides for teams.
Grammarly is not a content creation tool – it won’t write blog posts or ad copy from scratch. But as a writing quality layer that sits on top of everything you do, it’s unmatched.
