Is Grammarly Premium worth $12/month? Researched against 5 alternatives — here's who should pay, who should stay on the free plan, and when QuillBot wins instead.
Grammarly is the most widely adopted AI writing assistant available — 40 million users, integrations with 500+ apps, and a free plan with no word limit. The browser extension works across Gmail, Google Docs, LinkedIn, Word, and virtually every text field in Chrome. Free plan covers grammar, spelling, and punctuation. Premium ($12/month) adds tone detection, full-sentence clarity rewrites, vocabulary suggestions, and plagiarism checking. The most useful Premium feature for professionals is the full-sentence rewrite — it doesn't just flag passive voice, it rewrites the entire sentence in active voice so you can accept with one click. The plagiarism checker scans against 16 billion web pages, adequate for academic and professional use. Main limitation: Grammarly applies formal grammar rules to intentionally casual or creative writing. If your writing style relies on fragments, em-dashes, or unconventional structure, Premium suggestions feel like interference. In that case, disable the extension per-site. The free plan remains the strongest no-cost writing tool for everyday use.
