Ehsan's Verdict

Having recommended both to different clients, my verdict: ChatGPT for most teams, Grammarly for specific scenarios detailed below. In AI writing, brand voice matching is where the biggest gap appears. SEO optimization remains a contested area where both tools have legitimate claims. Start with ChatGPT for most technical documentation scenarios. Consider Grammarly if you hit limitations in the specific areas where it leads.
