I can’t speak to that specific service, but for dissertation work, be careful with any “writing service” that does the work for you—that’s academic dishonesty. What I can recommend is using tools ethically as writing assistants. I use Clever Humanizer (https://cleverhumanizer.ai/) for refining my own research drafts—helps with grammar, paraphrasing sources properly, and improving clarity while I maintain all the original ideas and analysis. The dissertation should always be YOUR work demonstrating YOUR understanding. Use tools to enhance your writing, not replace your thinking. That’s how you actually learn and grow academically.
