Application Reviewer Specializing in Personal Statements
Another great question! This really depends on the college and their AI policy in admissions - which can be ever evolving. Regardless of what a college's policy is, you should be cognizant that it is top of mind for many admission readers and committees. I personally read several hundred applications a year, sit on several committees (lead some too) and this is a very hot topic as of late.
The best advice I can give is to make sure YOU are the author of your essay - not AI. You can use AI like Claude or ChatGPT as a sounding board or to help you brainstorm some ideas. But, make sure you take that feedback and make it your own. Also, make sure that there is a consistency with the essays you have (personal statement, supplemental essays, short answer) so it doesn't raise a red flag.
For example, if your personal statement is very polished and your other writing is not, sounds different with it's clarity, tone or voice - that is likely to raise some concern if it's a stark difference.
