Secondary Sounds Like AI? Fix the Generic Lines
Why medical school secondaries read like ChatGPT even when you wrote them, the phrases that cause it, and a three-step rewrite with critique-only prompts.
Secondary Sounds Like AI? Fix the Generic Lines
"Sounds like AI" means "could be sent to any school by any applicant." In a 2025 pediatric residency study, four faculty raters named the source of a statement, AI or human, with 59% accuracy; in a 2025 McMaster study, eight raters scored AI-only essays no differently from human ones. What readers can see is a sentence with no fact in it.
So the fix is not to "sound more human." Our view: replace every sentence that echoes the school's mission page with two things: a fact only you have, and a resource only that school has. Use an AI tool, if you use one, only to point at the sentences that fail that test. Never to rewrite them. When the rebuilt draft is ready, a free review of your secondary essay reads whether your mission paragraph is backed by your own evidence.
Every study and page cited below was checked on November 7, 2026. Secondaries are school documents, so each school's own instructions on the secondary govern what help you may use. Read them on the secondary before you start.
Readers do not score "AI-ness"
Two 2025 reader studies and one 2024 preprint bear on this, and none is about AMCAS secondaries specifically. In the pediatric study (Curry et al.), four faculty named the source of 60 blinded statements right 59% of the time, where a coin flip is right 50% (our arithmetic). In the McMaster study (Choi et al.), ratings did not differ across four writer groups, one of them AI-only. And in a preprint covering 6,000 essays at one US medical school (Hagemann, Ratts and Spies), "Secondary essays demonstrated lower Phuman than Personal Comments essays, suggesting more AI use." Our reading of why: secondaries are written fast, in bulk, to prompts that invite mission language.
So "this sounds like AI" is a judgment about the writing. Our page on whether med schools can tell AI wrote your secondary covers what readers and that study found; the AI-use estimates page sets out each study's sample. This page is the rewrite.
What readers do grade is in the prompt. A mission or community-service secondary asks why this school and what you did. Our secondary prompts by school page lists the 2026-2027 wording.
The phrases that make a secondary sound generated
These are our constructed list, not a count from any dataset. Each phrase fails one test: it could appear in an essay to any school, by any applicant.
| Phrase | Why it fails | Replace with |
|---|---|---|
| "I am drawn to [school]'s commitment to…" | Restates the school's own mission page | The program or clinic you would join, by name |
| "underserved communities" | No place, no people | The county, clinic or population, and your role there |
| "holistic approach" | Says nothing a reader can check | What the curriculum actually does: a track, a week, a requirement |
| "a passion for medicine" | Claimed, not shown | The moment, with what you did |
| "fostering health equity" | Abstract verb, abstract object | What you changed, for whom, how often |
| "aligns perfectly with my values" | Asserts fit instead of showing it | Your evidence next to their resource |
| "diverse patient population" | Says nothing about which patients | The patients you met, in your words |
| "a pivotal moment that shaped me" | Labels the lesson before the event | Start with the event |
The general version of this problem, for college essays, is our words that fingerprint an AI-written essay page. The medical list differs because it is built from mission-page vocabulary.
The three-step why-us rewrite
- Find the mission sentence. Open the school's mission page next to your draft. Mark every sentence that uses its words.
- Replace it with your evidence. One fact only you have: a role, a place, a duration, a number, a moment.
- Attach the school's resource. One program, track, clinic or requirement from the school's own site, and what you would do in it.
Constructed example: a generic why-us, rebuilt in three steps
Constructed example, written by us, not a real applicant statement. Context (invented): an applicant writing a 1,500-character why-us secondary for "Haverleigh School of Medicine," a fictional school.
Before (51 words):
Haverleigh's holistic approach to medical education aligns perfectly with my values. I have a passion for medicine and a strong desire to give back to underserved communities. I am drawn to Haverleigh's diverse patient population and its focus on fostering health equity, and I know Haverleigh is where I can grow.
After (66 words):
For three semesters I taught an evening reading class for adults at the county library. One student, a home health aide, asked me to help her read a discharge summary she had been given in English. Haverleigh's first-year community project pairs each student with one partner organization for the year. I would bring that partner a plain-language discharge sheet and test it with readers like her.
What each step did. Step 1 marked all three sentences of the "before" version: each one is built from the phrase table above, and none holds a fact only this applicant has. Step 2 put in the library classes, the three semesters and the discharge summary. Step 3 named the first-year community project and said what the applicant would do in it. The "after" version uses no adjective about the applicant at all. It cannot be sent to another school without breaking, and it does not sound generated, because no tool knows about that discharge summary.
Critique-only prompts (and the cut-to-limit prompt)
An AI tool can find generic sentences faster than you can. It cannot supply the facts that replace them. The AMA's September 9, 2026 guide to AI in residency applications describes the same split for residency material: asking tools to "flag vague language, identify unsupported claims and pressure-test application material". The same use works on a secondary.
Constructed prompts, written by us:
| Prompt | What it returns | Use it? |
|---|---|---|
| "Here is the school's mission statement and my essay. List every sentence in my essay that repeats the mission's words." | Step 1, done for you | Yes |
| "List every sentence that could go to a different school unchanged." | The generic lines | Yes |
| "List every claim I make about myself that has no example in the essay." | Unsupported claims | Yes |
| "Cut this to 1,500 characters using only my words. Delete; do not add or rephrase." | A version at the limit, still yours | Yes, then check every cut |
| "Write a why-us essay for Haverleigh." | The "before" paragraph | No |
| "Make this sound less like AI." | The tool's rewrite of the tool's text | No |
| "Make this more compelling." | More adjectives | No |
Before you use any prompt, read the school's instructions on the secondary itself. They are the rule for that essay. TMDSAS applicants certify that their written passages, including "optional essays", "are my own and have not been composed or generated by a third party" (TMDSAS application certification). We could not verify the AMCAS certification on November 7, 2026; the AAMC's pages blocked our check. Read the AMCAS certification statements yourself.
The countercase: some secondaries are short logistics questions (where else are you applying, gap year plans). They do not need a rebuilt paragraph. A plain one-line answer is right, and the three steps are for the why-us, mission and community essays only.
Questions about secondaries that sound like AI
My secondary sounds like AI but I wrote it. Will a school think I used AI?
We cannot tell you what any school concludes. In the one study above that tested it, raters named the source correctly 59% of the time. What they can see is a paragraph with no fact in it. Run the three steps and the question goes away.
Should I run my secondary through an AI detector before I submit?
A detector score does not tell you which sentence to fix. The phrase table and the three steps do. Our does AMCAS check for plagiarism page covers what each health application service says about scanning essays.
Can I use an AI tool to shorten my secondary?
Use the cut-to-limit prompt above: delete only, using your words, then check every cut. Read the school's secondary instructions first, since they set the rule for that essay.
How do I make a secondary sound like me?
Put one fact in every sentence that only you could write: a place, a role, a number, a moment. Then read it aloud. If you would not say a sentence at the interview, rewrite it.
