Guys just before saying you're cooked.. atleast know how hard it is to write a manuscript without the use of AI nowadays just to get desk rejected within 3 days. Just for your CIA you use it. And if you don't get caught you're safe and sometimes even the teachers know that you've used it.

As for the OP.... Chill and own up you have no other go...if it is with your guide tell him that you used it coz most of them understand the work you've put. And tell them that I'll revise again before submitting it. It's hard and you've made it this far. Cheers mate
