What percent of your paper is written by AI and is it unethical?[D]

Hello folks,

Just started contributing into the writing for research, previously I just used to experiment and work on results, tables and plots.

Obviously using AI to generate content for paper is unethical and wrong in many aspect. But what about using it to correct your grammar and comprehension. Technically it will also considered as AI written but is it okay to do this atleast in the literature review, introduction and description for the experiment?

To be honest, I like writing and when I asked AI (chatgpt and others) I see that it is much easier to read and interpret, which I think is good for the community and on the other hand, it may be considered unethical by many.

When I ran a 'AI-text detector' on many of paper I'm using as reference from last 1~ year, I usually get a 50-70% score.

What do you all think?
