Pros

Works seamlessly across 500,000+ apps and websites through browser extensions, desktop apps, and mobile keyboards, providing consistent writing assistance everywhere you type.

The tone detection feature provides real-time feedback on how your writing will be perceived by readers, helping you strike the right emotional note in sensitive communications.

Deep integration with the Notion workspace means the AI has full context of your notes, documents, and databases, producing more relevant and personalized results than standalone AI tools.
The Q&A feature lets you ask natural language questions about your workspace content, turning your knowledge base into an intelligent assistant that surfaces information instantly.

Cons

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.

Notion AI requires an active Notion subscription and an additional per-member AI add-on fee, which means the total cost can add up quickly for larger teams already paying for Notion.
The AI is confined to the Notion ecosystem and cannot be used outside of the Notion editor, so users who work across multiple tools will still need separate AI solutions for other platforms.
While the Q&A feature is powerful, it can occasionally struggle with very large workspaces or return results from outdated pages, requiring users to verify that the information is current.
