What ChatGPT can and can't do for letters of recommendation

ChatGPT can help you write a strong letter of recommendation, but knowing what it can and cannot do is important. Reviewers want to understand a candidate's character, motivation, and interactions with others to determine how well they fit with the program. As a human reviewer, you can show these traits through descriptions of specific moments only you know, such as staying behind to work through a problem or stepping up when a project stalls. That personal experience is the raw material ChatGPT needs from you before it can do anything useful.

What ChatGPT can do

• Write a first draft quickly, so you spend your time refining rather than starting from scratch

• Organize a candidate's achievements into a coherent, readable narrative

• Calibrate tone and formality for the specific context such as a graduate program, job application, or scholarship

• Tighten language and smooth transitions in sections you've already written

What ChatGPT cannot do

• Know that the applicant stayed after class every week or outperformed the graduate students in your seminar

• Speak to where the individual is headed and why you believe in their potential

• Capture the specific shared moments that signal a genuine relationship between you and the candidate

• Guarantee that an experienced reviewer won't recognize the letter as AI-generated

Is it ethical to use ChatGPT for a letter of recommendation?

Using artificial intelligence (AI) to help write a recommendation letter is more common than you might think. Research from foundry10 found that roughly 30 percent of teachers are already doing it, noting that using AI helps them produce better letters with less stress [1].

Some recommenders already use a template for writing letters of recommendation, simply swapping in details and personal examples about each candidate. You can use ChatGPT as a more sophisticated version of that same practice. Whether it crosses an ethical line, though, depends heavily on who is asking. Policies vary widely, and many programs haven't issued any formal guidance on the subject. 

Is it okay to use ChatGPT for a letter of recommendation?

Generally, yes, with conditions. Some academic organizations, like the American Association of Medical Colleges (AAMC) have issued guidance on the subject, emphasizing the importance of reviewing, revising, and taking full ownership of the letter, because your genuine assessment of the candidate remains most important [2]. However, other academic groups, like the Physician Assistant Education Association (PAEA),  explicitly prohibit AI use in recommendation letters, so it’s best to check the destination program's policy before you start [3].

How to use ChatGPT to write a letter of recommendation

The quality of a ChatGPT-assisted letter comes down to preparation and revision. Before you open the tool, pull together the candidate's key accomplishments, any specific examples or metrics you can reference, and a clear sense of the letter's purpose. Also consider your relationship to the candidate and the tone the letter should strike.

You typically get a more useful first draft when you provide concrete inputs to the model, but plan to revise. ChatGPT can give you a framework, not a finished product. The goal is a letter that sounds like you wrote it. Knowing how to create effective prompts and revise as you work is key.

ChatGPT letter of recommendation prompts

The prompts below walk you through three common scenarios you might encounter. Each includes a sample prompt and the reference letter ChatGPT produced. Use these prompts as a ChatGPT letter of recommendation template, and adapt the details to fit your candidate and context.

How to write a recommendation letter for a student

Your student asks you for a college recommendation letter. You know her work well, but you've been asked to write 20 other letters and need a strong first draft fast. Here’s one example of a prompt and the resulting draft you could use:

The prompt

Act as a high school English teacher writing a letter of recommendation for a senior applying to a four-year university. The student excelled in AP Literature, contributed thoughtful analysis during class discussions, and wrote a standout personal essay on her experience as a first-generation student. She is applying to study journalism. The tone should be warm and encouraging.

The ChatGPT letter of recommendation

Dear Admissions Committee,

It is my pleasure to recommend [Student Name], a senior in my AP Literature class, as she applies to your university to pursue a degree in journalism. Over the course of this year, I have had the privilege of watching her grow into one of the most thoughtful and engaged students in the classroom.

In AP Literature, [Student Name] consistently demonstrated an exceptional ability to read closely and think critically. During class discussions, she offered insightful analysis that pushed her classmates to consider new perspectives. Whether we were examining narrative voice in modern essays or unpacking symbolism in classic texts, she approached each work with curiosity, intellectual honesty, and a willingness to engage deeply with the material.

One of the most memorable pieces of writing I read this year was her personal essay reflecting on her experience as a first-generation student. In it, she wrote with clarity, honesty, and quiet determination about navigating unfamiliar systems while carrying the hopes of her family. The essay stood out not only for its strong narrative voice but also for the empathy and reflection she brought to her story, qualities that will serve her well in journalism.

Beyond her academic strengths, [Student Name] contributes positively to the classroom community. She listens carefully to others, builds on her peers’ ideas, and asks questions that move conversations forward. Her intellectual curiosity and respect for differing viewpoints create the kind of environment where meaningful learning happens.

I am confident that she will bring the same dedication, insight, and authenticity to your campus that she has brought to our classroom. Journalism requires careful observation, strong writing, and a commitment to understanding people’s stories, traits that [Student Name] already demonstrates with remarkable promise.

I recommend her to you with enthusiasm and without reservation. Please feel free to contact me if you would like any additional information.

Sincerely,

How to write a recommendation letter for a job applicant

A former team member is applying to a new role and has asked you for a reference. You remember his work clearly, but you haven't written a professional recommendation letter before. That prompt and draft could look like:

The prompt

Act as a marketing manager writing a letter of recommendation for a former team member applying for a senior content strategist role. He led a rebranding campaign that increased web traffic by 40 percent, managed two junior writers, and consistently met tight deadlines. The tone should be professional and direct.

The ChatGPT letter of recommendation

I am pleased to recommend [Candidate Name] for the Senior Content Strategist role. During his time on my team as a Content Lead, he consistently demonstrated strong strategic thinking, excellent leadership, and a remarkable ability to deliver high-quality work under tight timelines.

One of his most notable contributions was leading our company’s rebranding campaign. He oversaw the development of the new messaging framework, coordinated cross-functional collaboration with design and marketing teams, and ensured consistent implementation across all content channels. As a direct result of this initiative, our website traffic increased by 40 percent within the first several months following the launch.

In addition to his strategic impact, [Candidate Name] also managed two junior writers, providing clear direction, constructive feedback, and mentorship that helped elevate the quality and consistency of the team’s work. He balanced leadership responsibilities with hands-on content development while maintaining strict adherence to deadlines, often in fast-paced, high-pressure situations.

What stands out most about [Candidate Name] is his ability to combine creative storytelling with data-driven decision-making. He approaches content strategy with both vision and discipline, ensuring that every project supports broader marketing goals.

I strongly believe he will bring the same level of professionalism, initiative, and strategic insight to any organization he joins. I recommend him without reservation for the Senior Content Strategist position.

Sincerely,

[Your Name]

How to update a recommendation letter for a new opportunity

You already wrote a strong recommendation letter for a candidate applying to graduate school. Now she's applying for an academic scholarship and needs the letter adjusted to fit the new content. Here’s what that might look like as a prompt and draft:

The prompt

I have an existing letter of recommendation for a candidate applying to graduate school. She is now also applying for an academic scholarship. Please revise the letter to emphasize her research, experience, cross-cultural communication skills, and long-term academic goals while keeping the original voice and structure intact.

The ChatGPT letter of recommendation

Dear Scholarship Committee,

It is my pleasure to recommend [Applicant] for your academic scholarship program. I have had the privilege of working with [Applicant] for three years as a professor and advisor at the [School], and I can say without reservation that she is one of the most intellectually curious, disciplined, and research-driven students I have mentored in my twenty years of teaching.

Her thesis examined language policy in post-colonial West African education systems, drawing on both quantitative data and ethnographic fieldwork she conducted during a semester abroad in Ghana. Her project required the integration of policy analysis, field interviews, and statistical data, and she approached each component with remarkable methodological care. Her ability to move fluidly between theoretical frameworks and on-the-ground educational realities was exceptional for an undergraduate researcher. The final manuscript, submitted as a polished, publication-ready draft six weeks ahead of schedule, demonstrated a level of scholarly rigor and independence that I typically see only among graduate students.

Beyond her academic work, she has served as a peer mentor for international students in our department for two years, helping students from twelve countries navigate both academic expectations and campus life. In this role, she has demonstrated outstanding cross-cultural communication skills: she listens attentively, adapts her communication to diverse cultural contexts, and creates an environment where students feel respected and supported. Her patience, cultural sensitivity, and genuine interest in others’ experiences make her an unusually effective communicator across differences, qualities that also strengthen her collaborative research work.

[Applicant] has articulated a clear and compelling long-term vision: to return to Ghana after completing her doctorate and contribute to national education policy reform through research and public scholarship. She sees rigorous academic inquiry not as an end in itself, but as a tool for shaping equitable language policy and improving educational access. I have every confidence that she has the intellectual rigor, intercultural insight, and personal commitment required to carry this work forward and to make meaningful contributions to the field of international education.

I recommend her to you enthusiastically and without reservation.

Sincerely,

Dr. [Professor Name]

Tips for a stronger ChatGPT recommendation letter

ChatGPT can be a helpful tool when you have something real to say about the candidate and just need help saying it well. If that's where you are, these habits can help you create a well-written letter that serves the candidate.

• Review for accuracy: ChatGPT can overstate qualifications, introduce inaccuracies, or produce phrasing that sounds polished but doesn't reflect what you actually know about the candidate. You are putting your name on this letter, so make sure it's true.

• Edit for your own voice: Read the draft aloud and adjust the language to make sure the letter sounds like you. This includes adding specific details about the candidate that only you can provide.

• Be thoughtful about privacy: Entering someone's personal details into a public AI tool may expose that information beyond the conversation. Limit what you share to details you'd be comfortable making public, and check your account's data privacy settings before you start.

What are the six details that should be included in a letter of recommendation?

Six details to include in a letter of recommendation are your connection to the candidate, their standout character traits and behaviors, specific examples that illustrate those traits, how their work compares to their peers, why you believe they are a good fit for the organization, and your contact information. Some recommenders combine the traits and peer comparison into a single section.
