Cons

The public-by-default highlighting model may concern users who prefer to keep their reading habits and annotations private, particularly when researching sensitive or competitive topics.
Being web-only with no dedicated mobile app limits the ability to highlight and organize content consumed on mobile devices, where a significant amount of reading occurs.
The community features, while innovative, can feel underdeveloped compared to mature social platforms, and the user base is still growing, meaning some articles may have few or no community highlights.

The Premium plan at $12 per month (annual billing) may feel expensive for individual users, especially students, considering that basic grammar checking is available in many free tools.
Grammarly can occasionally be overly prescriptive with style suggestions, flagging intentional stylistic choices like sentence fragments, colloquialisms, or creative phrasing as errors.
The generative AI features in GrammarlyGO, while convenient, are less capable than dedicated AI assistants like ChatGPT or Claude for complex writing tasks, long-form content, or creative work.
