Residency Letter of Intent With ChatGPT: The Rules

Residency Letter of Intent With ChatGPT: The Rules

No NRMP rule names AI. The NRMP says it "has not taken any stance on the use of AI-generated content". What does govern a post-interview letter is the 2027 Match Participation Agreement's accuracy clause: everything you send a program during recruitment must be complete, accurate and not "plagiarized".

So the risk in an AI-drafted letter of intent is not a detector. It is a sentence you did not decide. An AI tool will write "you are my first choice" for every program you name, and it will invent a program detail if you let it. Our view: use an AI tool to cut and to find your generic sentences; type the interest sentence and every program fact yourself. If the letter is ready, a free review of your residency letter reads it for exactly those two things.

Every NRMP and AMA page quoted below was checked on November 7, 2026. The AAMC's page on AI in its service programs blocked our automated check that day, so this page quotes nothing from it. Read it yourself at Use of artificial intelligence in AAMC service programs before you send anything.

What covers a letter sent after the interview

Three documents apply. None of them is an AI policy.

The NRMP's statement on AI. In September 2024 a fake "integrity screening" memo circulated. The NRMP's response (September 13, 2024) says:

"This statement is fake and was not issued by the NRMP. The NRMP has not taken any stance on the use of AI-generated content or “integrity screening”, nor do we provide guidance to programs on screening candidates in the residency application process."

The 2027 Match Participation Agreement, §6.3. You are responsible for the accuracy of "All written, electronic, and verbal information provided to programs and program representatives throughout recruitment, the onboarding cycle, and through the 45th day following the appointment start date". The section ends:

"Applicants who submit incomplete, misleading, false, or plagiarized information may be deemed to have violated this Agreement."

A letter of intent is written information you give a program during recruitment. That clause covers it, whoever drafted the words. Source: NRMP 2027 Match Participation Agreement for Applicants.

The communication rules. §6.4 of the same agreement lets you volunteer your interest and bars you from asking a program for a ranking commitment. The NRMP's Match Code of Conduct for Applicants adds that rank lists should rest on "their true preferences". Our 2027 NRMP letter of intent rules page quotes both in full, with the March 3, 2027 deadline and the specialties that ask for no letters.

Why AI letters read the same

An AI tool given "program name + specialty + I loved my interview" has only public inputs, the same website every other applicant read, so it writes a paragraph any of them could send.

The AMA's September 9, 2026 guide to AI in residency applications quotes Ankita Bhatia, who the AMA says recently concluded her tenure as its director of AI strategy and engineering: "To distinguish yourself, it [your story] needs to be ungeneratable." For a letter of intent, "ungeneratable" has a concrete test. The letter needs three things no tool can know:

1. One detail from your interview or rotation that is not on the website: a case, a conference, a resident's answer.
2. One conversation, with the person's role, and what you learned from it.
3. One program feature tied to what you would do with it, in your words.

Constructed example: the generic paragraph and the rebuilt one

Constructed example, written by us, not a real applicant's letter. Context (invented): an internal medicine applicant writing to "Thornfield Medical Center" after a sub-internship there.

AI-drafted version (59 words):

I am writing to express my strong interest in the Internal Medicine Residency Program at Thornfield Medical Center. Your program's commitment to clinical excellence, diverse patient population, and supportive learning environment aligns perfectly with my goals. I was deeply impressed by the collegiality of the residents during my interview, and I am confident I would thrive in your program.

Rebuilt version (67 words):

During my sub-internship on Thornfield's night float, the senior resident walked me through a DKA admission at 3 a.m. and then had me present it at morning report. That habit of handing the intern the case is why Thornfield is my first choice. I want to train where I present my own patients early, and I would join the quality-improvement track Dr. Obuya described at my interview.

What changed. The first version could go to any program by swapping one name. Phrases like "commitment to clinical excellence" and "supportive learning environment" could describe any program. The second version names a rotation, a moment, a person's role and a track. Only one applicant can write it. It also contains a first-choice line, which only one program may receive. That is the next section.

Rank statements: only the true one

Our view: a first-choice sentence goes to one program, and you type it yourself. An AI tool does not know your rank list. Ask it for "a letter of intent to Program A" and then "a letter of intent to Program B", and it writes "you are my top choice" twice. If you send both, the second letter is false information to a program during recruitment, which is what §6.3 covers.

Pick the letter by the sentence you can stand behind:

The countercase: some applicants decide never to state a rank position in writing. That is a valid choice under the NRMP rules, since §6.4 lets you volunteer interest but does not require it. Then the letter of interest row is your ceiling. Our residency letter of intent examples show one letter of each type, and the ranked-to-match email guide covers what to do when a program writes to you first.

Prompts that help and prompts that hurt

The AMA guide gives a prompt structure. Bhatia's advice, as the AMA quotes it: "give it a specific role, like copy editor, asking it to focus on grammar, consistency and structure rather than changing your voice", and "be clear about what it should not do—rewriting sentences—and ask for a list of edits so you can review every change." The same guide says an AI chatbot "is a poor source for deadlines, visa details, program requirements, score benchmarks and citations". Program facts in your letter come from the program's site and your notes.

Constructed prompts, written by us:

Pharmacy residency letters through PhORCAS

A PhORCAS letter of intent is a different document. You upload it with the application through PhORCAS program materials, before any interview. The PhORCAS Program Materials page says to use that section "If the specific programs you are applying to have any additional application requirements". The two PhORCAS help-center pages we read on November 7, 2026 contain no AI or plagiarism wording, so each program's instructions govern. The prompt table still applies. The pharmacy residency letter of intent guide covers that letter's structure, and what to check first in a PhORCAS letter covers its review.

Before you send: the five-line check

1. Interest sentence. You typed it. It states your real position from the table above.
2. First choice. If the letter says first choice, no other program has received or will receive that sentence.
3. Every program fact. Each one came from the program's page or your own notes, not from a tool.
4. The paste test. No sentence could go to a different program unchanged.
5. No ranking question. Nothing asks where you stand on the program's list.

A letter that fails line 2 or 3 is a §6.3 problem. A letter that fails line 4 is a weak letter. Fix both before the March 3, 2027 rank order list deadline. Thank-you notes follow the same five lines. The residency interview thank-you email page covers when to send one.

Questions about AI and residency letters

Can I use an AI tool to write my residency letter of intent?

No NRMP rule bans it. The NRMP says it has taken no stance on AI-generated content. The agreement's accuracy clause still covers every sentence you send, so the commitment line and the program facts must be true and yours. We could not open the AAMC's own page on AI on November 7, 2026; read it on the AAMC page linked above.

Will a program know an AI tool wrote my letter?

Nothing the NRMP publishes describes a scan of letters. What a program can see is whether the letter could have come from anyone. The rebuilt paragraph above passes that test. The generic one fails it, whoever wrote it.

Can I send the same AI letter of intent to two programs?

Not with a first-choice sentence in it. One program can be first on your list. A letter of interest without rank words can go to more than one program, if each version carries that program's own details.

Does the same apply to a thank-you email?

Yes. A thank-you email is information you give a program during recruitment, so §6.3 covers it. Keep it short and specific. Applying to medical school, not residency? See AI on medical school update letters and letters of intent.
