I used 99Papers https://www.99papers.com/ for support with structure and ideas in academic work, and my experience was positive when used responsibly. I asked for help organizing my own arguments and improving clarity, and the delivery was original and well-structured. Communication was fast, and revisions were handled properly. It wasn’t about submitting someone else’s work blindly, but using it as academic support and a reference. As a learning aid under time pressure, it was helpful and worth the cost.
