is it ok to use AI for drafting internship cover letters?

Totally fine, and here's why: nobody in hiring expects cover letters to be works of literary art. They're professional communication documents with a fairly standardized structure, and using AI to get the structure and tone right is functionally no different from using a template, which literally every career center recommends.

The important thing is personalization. A generic AI-generated cover letter that could apply to any company is obvious to any experienced recruiter and will get tossed immediately. But if you use AI to create a solid structural first draft and then customize it meaningfully for each specific company, adding concrete details about why you want that particular role at that particular organization, referencing their recent work or values that genuinely resonate with you, you'll end up with something better than most fully handwritten cover letters I've seen.

I used this exact approach for my internship search last year and got callbacks on about a third of my applications, which was significantly above my hit rate the previous year when I painstakingly wrote every letter completely from scratch.

It's perfectly fine as a starting point and structural scaffold, but please don't send the raw AI draft as-is. Hiring managers who read hundreds of applications can tell when something was generated and left unedited. The tone is always slightly off: either too formal in a way that doesn't match a student's actual voice, or so generically optimistic that it reads like a template rather than a person. Use AI for the bones and the structure, then rewrite the substance in your own voice with your own specific experiences. That's the balance that works.

Not only is it fine, I'd argue it's the strategically smart move for anyone sending out a high volume of applications. Here's the specific workflow I'd recommend based on what worked for me and several friends who went through recruiting last cycle.

Start by writing one genuinely strong cover letter completely by yourself for your absolute top-choice company. Pour real effort into this one. Make it specific, authentic, and clearly reflective of who you are as a candidate and what you'd bring to that particular role. This becomes your master template and your reference document for voice and substance.

Then use AI to adapt that master letter for each subsequent application. Feed it the specific job description alongside your master letter and ask it to adjust the emphasis, swap in relevant details about the new company's work, mission, or recent projects, and match the professional tone of the job posting. This is exactly where AI saves you enormous time, because adapting an existing strong letter to a different context is the kind of structured, pattern-based rewriting that AI does exceptionally well.

After the AI generates each adapted draft, go through it manually and do three critical things. First, replace any generic phrases with specific details that demonstrate you've actually researched this company beyond their homepage tagline. Second, make sure your personality and authentic voice still come through clearly, because AI tends to sand off all the interesting, distinctive edges of your writing and replace them with polished blandness. Third, verify that every single claim you make about yourself is true and backed by a concrete example. AI loves generating vague accomplishment statements like "demonstrated strong leadership in collaborative team environments" and you need to replace every one of those with a real, specific story from your actual experience.

The final quality check is reading it out loud. If any sentence could have been written by literally anyone applying to literally any job, rewrite it until it couldn't have been. The goal is a letter that could only have been written by you, specifically about this specific opportunity at this specific company.

@maya_p is exactly right that unedited AI cover letters are painfully obvious to experienced readers. But thoughtfully edited and personalized ones are genuinely effective, often more so than purely handwritten letters that lack structure. The key is treating the AI output as raw material to be shaped, not as a finished product to be submitted.

As an international student, AI has been genuinely helpful for cover letters specifically because professional communication conventions differ so much across cultures. In my home country, cover letters are significantly more formal and hierarchical in their tone and structure. American cover letters are supposed to be personable, confident without being arrogant, and slightly conversational, which is a register I struggled to hit naturally without sounding either too stiff or too casual.

I use AI to help me nail the cultural tone and professional register, then I add my own specific experiences, motivations, and personality. The result sounds authentically like me but in the right linguistic register for the audience I'm addressing. I don't think there's anything dishonest about that approach. It's functionally no different from asking an American friend or a career counselor to read your letter and tell you where the tone feels off.

@ethan_w the master template approach is excellent advice. Writing that one truly genuine letter first means everything after it has a real, authentic foundation rather than being AI from the ground up.

I think whether it's "ok" depends on what exactly you mean by the question. Ethically, there's genuinely nothing wrong with it. Cover letters aren't academic submissions held to scholarly integrity standards. They're professional marketing materials. You're selling yourself and your qualifications to a potential employer, and using available tools to do that effectively is strategic, not dishonest. Nobody questions whether it's ok to have a career counselor review and suggest edits to your cover letter, and AI is serving a similar structural function.

Practically though, I'd add one important warning: don't let AI write claims about you that aren't actually true. I've reviewed AI-generated cover letters for friends that casually embellished skills or subtly invented experiences because the model was optimizing for what sounds impressive and relevant, not for factual accuracy about a specific person. If your letter claims you're proficient in Python data analysis and you've never written a line of Python, that fabrication is going to blow up spectacularly in the technical interview.

Also worth knowing that some larger companies now run application materials through AI detection tools, not necessarily to penalize you but to flag mass-produced, non-personalized applications for deprioritization. That's another strong practical reason to personalize heavily rather than submitting lightly edited template output.

@j_thompson a third callback rate is really solid by any standard. That's significantly above average for most internship applicants in the conversations I've had.
