For many students, the prospect of writing their personal statement—a meaningful, memorable exploration of their character, values, and growth in a mere 650 words that may make or break the chances of being accepted to their dream school—is, rightfully, intimidating.

Amidst commitments to senior year coursework like honors, AP, and dual-enrollment classes; leadership positions and extracurriculars; work and family commitments; and trying to have a little bit of fun with friends before graduation, it can be tempting to hand the weighty responsibility of the personal statement over to generative AI tools like ChatGPT.

While some students may use these tools to save time, others may rely on them due to a lack of confidence in their own ability to come up with a strong topic or write a polished essay. And this pull has only gotten stronger as AI is integrated into applications like Google Docs, “Write with Gemini…” beckoning from the bottom of a blank page. With all of these factors in mind, you may be thinking, “AI can write my essay for me.” And it can.

But you can do it a lot better. In this post, we’ll discuss what makes a great college essay, where AI tools struggle, what colleges think about AI use, where in the writing process you may be able to use AI, and where a human touch is best.

Qualities of an Effective College Essay

After working with Princeton Tutoring’s founders to develop a college essay writing curriculum based on my years of experience supporting students as they brainstorm, draft, revise, and polish their personal statements, I’m convinced that almost any topic can make for a compelling college essay: Harry Styles. How to paint a self-portrait. Being a middle child. Writing in cursive. Hot sauce. Going on “side quests.” Turning into your parents. Airport layovers. Fishing. Hating fish. Even though you can write about almost anything, the best college essays tend to share a few key qualities:

  1. They allow for introspection and reflection, offering insight into what a student has learned from their life experiences and how they view the world.
  2. They are full of a student’s voice, showcasing a student’s unique way of expressing themselves on a page.
  3. They include descriptive sensory details and engaging imagery.
  4. They are honest and authentic, providing candid and vulnerable insights into who a student is.
  5. They are unconventional and distinct, veering away from predictable or expected topics and structures.
  6. They are well-written, using techniques and language that are not generic or boring.
  7. They are meaningful, actually connecting to the writer’s values, beliefs, and identity.

Ultimately, the essay should help round out a student’s holistic application by showcasing their unique voice; illustrating their particular perspectives, character traits, and values; and conveying a significant component of who a student is.

Where AI Falls Short

The problem is that the very qualities that make for an outstanding college essay are exactly the things that AI has a hard time doing well. In an interview, OpenAI CEO Sam Altman acknowledges that even in the future, improved AI models will likely only be capable of middling creative writing, like poetry that equals “a real poet’s okay poem.”

This shortcoming is due to the way in which generative AI is built. First, it is exposed to a huge amount of writing, which includes everything from old tweets to Wikipedia to great works of literature, and begins to detect patterns that teach it basic grammar and word associations. Humans then start to engage with the model, evaluating and tweaking responses based on rigid rubrics.

While this approach results in AI models that are technically competent writers, it does not allow for the creativity that makes for really good, compelling writing; in her exploration of AI writing in The Atlantic, technology writer Jasmine Sun describes generative AI models as “rule-following teacher’s pets.” Reading the entire canon of great literary works can neither replace nor replicate the experience of living in and experiencing the real world.

Modern LLMs are built in a way that is antagonistic to great writing; they are engineered to be rule-following teacher’s pets that always have the right answer in hand.

Research has found that AI-written personal statements demonstrate less novelty and diversity in both content and style than those written by real students. Researchers at the University of Pennsylvania discovered that, from the very beginning of the writing process, using generative AI for brainstorming led to a “decrease [in] idea diversity” and, ultimately, “a narrower scope of novel content produced.” What’s more, research out of Georgetown University found that this homogeneity “persisted despite efforts to enhance AI-generated content through both prompt and parameter modifications.”

This trend is consistent across different AI tools, according to researchers at the University of Southern California (USC). While this uniformity is becoming less pronounced as AI continues to develop, a team led by a researcher at the University of Copenhagen learned that even the newest models suggest fewer diverse ideas than a basic web search.

Additionally, AI “struggles to preserve style and authorial voice,” according to research from Carnegie Mellon University. Researchers at USC have noted that using AI as part of the revision process can “alter stylistic elements” in a way that “emphasiz[es] conformity over individuality” when it comes to voice. This tendency towards generic writing is a problem, especially for those who may be thinking about using AI to write their college essays, because the best personal statements explore a unique topic in an unexpected way.

These characteristics of AI may be especially troublesome for students from diverse cultural backgrounds. Because of how it’s built, generative AI often “reflects and reinforces dominant styles while marginalizing alternative voices and reasoning strategies,” as described by another team at USC. Researchers at Cornell University discovered that AI “diminish[es] nuances that differentiate cultural expression” when being used to complete “culturally grounded writing tasks” by users of different races, ethnicities, and nationalities.

Even with additional prompting about an individual student’s identity, AI tools were unable to accurately replicate the “linguistic patterns observed in human writing” from specific groups, according to another team at Cornell. In fact, research out of Stanford University explains that AI tools tend to “misportray and flatten the representations of demographic groups,” so that additional prompting may actually create a more one-dimensional depiction of a student’s identity.

To put it simply, AI-generated writing exhibits a narrower range of topics than writing by humans, employs a more generic style and voice, and may contain particularly superficial representations of students from diverse cultural backgrounds. Overall, the team at Cornell summarizes it like this: today’s generative AI fails to “authentically replicate the diverse and nuanced voices of human authors, resulting in outputs characterized by rigidity, homogeneity, and a generic quality distinctly separate from human-authored texts.”

Will Colleges Know if You Used AI?

The homogeneity and stylistic tics of AI-generated writing also means that it is easy to distinguish from something written by a human. We’ve all seen formulaic AI constructions like “It’s not X, it’s Y,” “not only but also,” and an over-reliance on the “rule of three,” or grouping ideas in threes for rhetorical impact. A recent article published in The Economist finds that generative AI also tends to use more long words, uncommon words, and scientific jargon than humans.

In more recent updates, AI has stopped overusing the em-dash—an exciting update for people like me who also tend to overuse this particular punctuation mark. In fact, AI uses much less punctuation overall. This is likely because AI models generally write longer sentences and rarely vary their sentence length. For many of these reasons, when the team at Cornell “trained an AI model to differentiate between human- and AI-written essays, it worked with near-perfect accuracy. This finding suggests that… universities and colleges can likely identify essays that are primarily AI-generated.”

Each college or university’s policy about AI use for application materials differs. Some schools allow for limited AI use. For example, Caltech advises you to “ask yourself whether it would be ethical to have a trusted adult perform the same task you are asking of ChatGPT. Would a teacher be able to review your essay for grammatical and spelling errors? Of course! Would that same teacher write a draft of an essay for you to tweak and then submit? Definitely not.”

In contrast, other schools forbid any use of AI. Georgetown University, for example, requires that applicants sign a statement confirming that they did not use AI for any part of their application, “including brainstorming, drafting, and even basic grammar checking or editing.” You should always check the AI policies of each school you’re applying to, but you’re also better off erring on the side of caution—that is, using little or no AI.

Setting aside the ethical problems with having a machine completely write what is supposed to be your applicant’s personal essay, they risk submitting a cookie-cutter piece that may be structurally flawless but could have been sent in by anyone. It’s the opposite of authentic.

Despite differences between AI policies among individual schools, essentially all schools agree that submitting AI-generated content as your own is unethical; doing so typically results in being disqualified from admission.

Some schools go even further. For example, Harvard University not only denies admission to applicants who have submitted essays written by AI. Students who were admitted to Harvard may have their offer withdrawn, registered students may have admission revoked, and even students who have already graduated may have their degree rescinded if they are found to have used AI in their application materials.

Where AI Can Help with Your College Essays

Are there some parts of the writing process where AI can be helpful? Sure.

In the planning stages, AI may be able to help create a timeline of concrete to-dos to help ensure you’re meeting your deadlines. AI can also generate thoughtful brainstorming prompts to help facilitate introspection and reflection (although you should avoid using it to suggest specific essay topics). As you move into the outlining and drafting stage, AI can suggest a variety of potential structures for your essay. Lastly, AI may be useful during the revision process. In particular, it can help to ensure clarity by identifying repetitive word choices or unclear wording, checking for appropriate tone, and pointing out grammar issues or usage errors.

It is important to note that if you do decide to use AI as a tool as you write your essay, at no point should you let it actually change your text—you should always implement any suggestions yourself.

Conclusion

So, what does all of this mean for you as you set out on your college essay writing journey? While AI can write an essay, it can’t write your essay. The very qualities that make for a successful personal statement—introspection and reflection; a unique authorial voice; descriptive, engaging writing; honesty and authenticity; and an element of unconventionality—are, by design, exactly the things that AI struggles to do.

AI-generated writing tends to be generic, with little in terms of either content or style that makes it stand out. The formulaic nature of AI-written text makes it easy for colleges and universities to recognize when applicants submit essays written or “polished” by AI. And while individual schools’ AI policies differ, nearly every school disqualifies any applicant who submits an AI-generated admissions essay.

One of my favorite parts of college essay tutoring is asking my students to read their finished essays out loud after six or eight or even ten weeks of work. Some are initially reluctant, their voices soft and halting, while others are eager, radiating certainty. But in every case, as they reach the closing paragraph, the final sentence, the last words they have written, they wear a confident smile that tells me they know they have done it—captured just one tiny, perfect piece of who they are.

And AI definitely can’t do that.
