What Free covers
Free focuses on core writing correctness, tone visibility, and a smaller monthly AI prompt allowance. It can be enough for casual email, short messages, and basic proofreading.
What Pro adds
Pro adds full sentence rewriting, tone adjustment, more personalized suggestions, plagiarism and AI generated text detection, and a much larger monthly AI prompt allowance.
Who may notice the difference
Students working on frequent papers, professionals writing client facing material, job seekers polishing applications, and people who write in English often may have more opportunities to use the paid features.
Try the workflow before the subscription
A practical approach is to use Free in the places where you normally write. If you keep running into paid suggestions that match real needs, you will have a clearer reason to consider Pro.
