Best for individuals or teams who want reliable grammar, tone, and plagiarism tools with AI rewriting and a usable free tier. The Pro plan adds deep rewriting and 2,000 AI prompts per month but costs significantly more than many rivals. Those needing more affordable or privacy-focused writing tools should consider alternatives like LanguageTool or ProWritingAid.
What is Grammarly?
Grammarly is an AI writing assistant that checks grammar, spelling, clarity and tone across the web and apps. Its generative features can rewrite, shorten or adjust the tone of text, helping professionals and students write clearer, more polished content everywhere they type.
How we scored Grammarly
Grammarly earns high marks for capability and ease of use thanks to its deep feature set and broad platform support. Delivery is strong but docked slightly for the legal controversy. Value scores lower because the Pro plan is notably more expensive than many alternatives.
Pros and cons
What we liked

Who should use Grammarly?
Anyone who writes regularly - students, professionals, or teams - will find Grammarly’s free tier useful for catching basic errors and experimenting with AI prompts. If you need deeper rewriting, tone control, plagiarism checks, or brand consistency, the Pro plan delivers that - but at a premium price. Organizations that require admin controls, single sign-on, and security features may benefit from the Enterprise plan. If you’re on a tight budget or prefer open-source or privacy-focused tools, consider LanguageTool or ProWritingAid instead.
