Princeton has no AI specific rule, but its required graded written paper gives readers a classroom authenticity baseline every essay is compared against, making AI polished prose uniquely risky at Princeton.
Stanford has no AI specific rule, but the authorship certification and fraud terms prohibit generated language, and Stanford's voice heavy short essays make AI polish a wasted answer to the question actually being asked.
The 2026-2027 deadlines fall into three walls: October 15 for the earliest public rounds, November 1 for nearly all ED, EA, and REA programs, and January 1-2 for Ivy Regular Decision, with the UC filing window closing December 2.
Duke did not ban AI: its 2025-2026 supplement asks applicants to reflect on how they use it, grading the honesty and specificity of the thinking. What strong and weak answers look like, and where the authorship line still sits.
College AI policies split into four camps: Yale, Cornell, and Brown prohibit AI generated content, Duke requires a reflection essay, Brown, UChicago, and Caltech add video verification, and most others govern AI through integrity codes. The full table.
MIT has no AI specific rule, but its own application portal carries its own authorship attestation, and MIT's short answer format plus its stated preference for genuine, imperfect voices makes generated prose both a violation and a wasted answer.
Brown, UChicago, and Caltech anchor the growing group of selective colleges asking for short video introductions: one to two minute unscripted recordings that anchor authenticity as essay trust declines. Who asks, and how to prepare.
No. Brown prohibits AI generated content and permits AI only for spelling and grammar review, then adds a video introduction so readers can compare every essay against the unscripted person. Both rules, translated into practice.
Purdue admitted roughly 37,800 from about 87,000 applications for the Class of 2029, a 43.4% rate that rose by design. Engineering near 34.7%, Education near 70.5%, test expected, and a November 1 deadline that closes impacted majors.
Villanova's acceptance rate rose to about 27% on a record 26,306 applications as the university deliberately expands its class, while Early Decision admitted roughly 60% per the CDS. The four round calendar, the profile, and the ED math.
Ohio State admitted 40,047 from a record 81,392 applications for the Class of 2029, a 49.2% rate down eleven points in one cycle. In state and out of state admit at nearly identical rates, and the transfer door runs near 85%.
UW Madison admitted 30,167 from a record 73,912 applications for the Class of 2029, a 40.8% rate with a mild residency split: 56.4% in state, 40.3% out of state. Average GPA 3.9, over half above 4.0, genuinely test optional.
No. Cornell prohibits AI generated material in application materials, and its college specific essays demand named programs and verifiable plans that generated prose fakes poorly. The rule and the structure, both explained.
UF admitted 18,169 from a record 91,896 applications for the Class of 2029, a 19.8% acceptance rate, down from roughly one in three five years ago. Admitted GPA 4.5-4.7, SAT 1380-1510, test scores required, EA the real front door.
UT Austin admitted 20,154 from a record 90,690 applications for the Class of 2029, a 22.2% rate hiding two systems: automatic admission for top Texas graduates, tightening to top 5% for Fall 2026, and near 10% odds for everyone else.
UW admitted 30,446 from 72,933 applications for the Class of 2029, a 41.8% rate under the most contrarian design in flagship admissions: no early round, one November 15 deadline, test free review, and direct to major gates that govern CS.
