Can Claude check grammar like Grammarly?
Claude can identify and correct grammar errors if you ask directly (e.g., 'proofread this email'), but it won't do so automatically or provide real-time feedback. It also won't explain grammar rules in detail like Grammarly does. For passive, always-on grammar checking, Grammarly is the only choice.
