Indispensable for professional writing
As a non-native English speaker working in a US company, Grammarly Premium has given me tremendous confidence. My emails and reports are more polished, my tone is more appropriate, and I've actually learned proper grammar by seeing the corrections. Worth every dollar.
Good but can be overly cautious
Grammarly catches genuine errors that I miss and the clarity suggestions are often spot on. However it sometimes flags perfectly correct writing as problematic. I've learned to evaluate suggestions rather than blindly accept them. Overall very useful tool.
Made my academic writing much better
Writing research papers in English as a second language is challenging. Grammarly Premium not only catches errors but explains why they're wrong, which has genuinely improved my writing skills over time. The plagiarism checker gives me peace of mind for submissions.
Final Verdict
Grammarly Premium is an invaluable tool for anyone who writes professionally. Its combination of grammar correction, tone analysis, and AI writing assistance makes it the most comprehensive writing aid available. The universal integration means it works wherever you write, making it a set-and-forget productivity enhancer.
