To be honest, I used to doubt the effectiveness of such services, but one day I came across a platform that really surprised me. There is a unique tool - essay analyzer, which literally in seconds gives a detailed assessment of the work on a variety of parameters: structure, argumentation, grammar, logic of presentation and even stylistics. Everything is very transparent, without unnecessary “waters” and incomprehensible explanations site here
https://textero.io/essay-grader . I especially liked the fact that the site does not just point out mistakes, but explains them with examples - so it is much easier to learn and correct. The interface is extremely clear, you can upload your text in one click, and you don't have to understand technical details. I uploaded one of my essays before handing it in, got a grade, recommendations, revised it and ended up with a top score. It's definitely a service that helps you not only “jumpstart the assignment” but also learn how to do better. It is suitable for both high school and university students.
