Can AI Models be Used to Judge Essays?

Explore top AI platforms like Merlin, ChatGPT, Copy AI, and Microsoft Copilot to enhance your essay writing with accurate, unbiased feedback and save valuable time.

Correcting your written work is mostly the task of a teacher. It is true that AI's can't replace the teacher, but definitely some aid is always appreciated. The advantage that AIs have over humans is that they are not caged with biases and will not hesitate to be harsh. They have no subjective beliefs, will provide nuanced and reliant feedback, and will spare us the need to rely on others for their inputs. Hence, they are great to judge and compare, free of biases. Having said this, I would recommend, get a final review from a well experienced professional of the field.
