College and university applications: what AI use is allowed, and how to use it honestly

Short answer

Only in limited ways, and the limits differ by school. Every source below agrees that the words you submit must be your own; passing off AI text as yours is treated as fraud or cheating. Brown, Caltech and UCAS accept a spelling and grammar check. Rules on brainstorming help vary. Write every sentence yourself, use AI for questions and feedback where allowed, keep your drafts, and read each school's policy every year.

What the rules say

Common App (US). The Common App's fraud definition, as quoted by Harvard and Brown, covers "intentionally misrepresenting as one's own original work: ... the substantive content or output of an artificial intelligence platform, technology, or algorithm." When you submit, you certify that what you send "is my own work, factually true, and honestly presented" (Harvard College, checked October 2026). The Common App's fraud policy page showed no body text when we checked, so we quote it through them.

UCAS (UK). "Generating (and then copying, pasting and submitting) all or a large part of your personal statement from an AI tool such as ChatGPT, and presenting it as your own words, could be considered cheating by universities and colleges and could affect your chances of an offer." You now "have to declare that your personal statement hasn't been copied or provided from another source, including artificial intelligence software." UCAS does name some help as fine: "ChatGPT can be used to check your personal statement draft for readability" (UCAS, undated). UCAS checks statements for similarity, and its applicant guide says: "The service we use, called Copycatch, finds statements that show similarity" (UCAS similarity guide, undated).

Universities add their own rules:

What is usually fine, and what is not

Where UCAS or a guide says yes and a school says no, the school's rule wins for its essay.

A prompt for questions and feedback only

Use this only where the school allows feedback. Take out names and details about other people (What not to paste). The prompt (the text you paste into the AI, not the essay question) is our suggestion.

I am applying to <SCHOOL>. Their AI policy for applicants says: <POLICY_TEXT>.
Here is my own draft for this prompt: <ESSAY_PROMPT>.
Rules for you:
- Do not write, rewrite or suggest replacement sentences, words or an outline.
- Ask me up to 5 questions that would help me say more clearly what I mean.
- Point to any sentence a reader might find unclear, and say why, in one line.
- Note any spelling or grammar errors by quoting them. Do not correct them.
- If my request breaks the policy above, say so and stop.
---
<MY_DRAFT>

Replace the following:

• <SCHOOL>: the school this essay is for.
• <POLICY_TEXT>: the school's AI wording, pasted from its own page.
• <ESSAY_PROMPT>: the essay question.
• <MY_DRAFT>: your draft, with personal details trimmed.

Revise in your own words. If a reply hands you a sentence anyway, do not use it.

Keep evidence of your process

Harvard says that if the committee has questions about "the authenticity of materials presented, they may be in touch directly with you to gather more information." UCAS says "any information you mention may need to be discussed or evidenced." Our suggestion:

1. Write in a tool that keeps version history, or save a dated copy of each draft.
2. Keep a notes file: topic ideas, memories, lists, the questions you answered.
3. Keep a short AI log: date, tool, what you asked, and what you changed afterwards (illustrative: "12 Sept, asked for questions on draft 3, added the bakery story myself").

The risks

• Detectors can be wrong. In one test, seven AI detectors (tools that guess whether AI wrote a text) wrongly flagged on average 61% of essays by non-native English writers (Liang et al., Patterns 2023). If you are flagged, your drafts and log are your answer: AI detectors: what they can and can't tell you.
• AI essays sound alike. Comparing over 150,000 admissions essays with over 25,000 from GPT-3.5 and GPT-4 (earlier versions of the AI behind ChatGPT), one study found "the AI-generated essays are most similar to essays authored by students who are males with higher levels of social privilege" (Alvero et al., Journal of Big Data, 2024).
