Example — written by InstaResume for an Internship
Fictional candidate. Your letter will be grounded in what you paste.
What you paste
priya, jr cs major, gpa 3.7, python sql excel git, coursework data structures + algo, built inventory tracker app solo, kaggle comp top 15%, hackathon 24hr 3rd place team of 4, avail may-aug, looking for summer internship, quick learner, used github for version control
What you get
My name is Priya, and I'm a junior Computer Science major with a 3.7 GPA seeking a summer internship where I can apply my coding and analytical skills. Through coursework in data structures and algorithms, along with hands-on practice in Python, SQL, Excel, and Git, I've built a solid technical foundation that I'm eager to bring to a real-world team.
On my own, I designed and built an inventory tracker application, managing the project from planning through implementation and using GitHub for version control throughout. I also competed in a Kaggle competition and placed in the top 15%, which sharpened my data analysis and problem-solving abilities under competitive conditions.
Most recently, I participated in a 24-hour hackathon as part of a four-person team, where we placed 3rd overall. That experience reinforced my ability to collaborate under pressure, communicate clearly, and deliver a working product on a tight deadline.
I'm available from May through August and would welcome the opportunity to contribute as a summer intern. Thank you for considering my application; I'd be glad to discuss how my background fits your team's needs.

Four more internship cover letter examples
Fictional candidates, each with a different hard problem. Every number in a letter below came from that candidate's own pasted notes.
Marketing internship, first-year student with no jobs yet
No employment history at all. Coursework, a club role and a class project are the whole evidence base — and they are enough, because internships are hired on trajectory rather than track record.
What you paste
freshman marketing major gpa 3.5, no jobs yet, social media chair for business club ran ig account grew 400->1100 followers 1 semester, canva + capcut, class project market research survey 120 responses presented to local bakery owner, hs yearbook editor, avail summer 20-30 hrs, spanish conversational
What you get
I am applying for your summer marketing internship. I am a first-year marketing major with a 3.5 GPA, and while I have not held a marketing job yet, I have been doing the work in the places available to me.
As social media chair for our business club I run the club's Instagram account, which grew from 400 to 1,100 followers over one semester. I plan and produce the posts myself in Canva and CapCut, which means I have also learned the unglamorous half — posting on a schedule when nobody is watching the numbers but me.
In a course project this year I ran a market research survey that collected 120 responses and presented the findings to a local bakery owner. Sitting across from someone whose actual revenue depends on the answer changed how I write a recommendation. Before university I edited my high school yearbook, so deadlines and other people's late files are familiar territory.
I am available 20-30 hours a week over the summer and I speak conversational Spanish. I would be glad to talk about what your team needs help with this season. Thank you for your consideration.

Finance internship with a GPA below the posted cutoff
The posting says 3.5 and the applicant has a 3.1 with an upward trend. The letter states the trend rather than hiding the number, and spends its evidence on things a GPA does not measure.
What you paste
jr finance major cumulative gpa 3.1 but 3.7 last 3 semesters after switching from bio, excel modeling coursework dcf + 3 statement, bloomberg terminal cert (bmc), student investment fund analyst covering 2 consumer names pitched both to committee, worked 20 hrs/wk campus dining whole degree, avail summer full time
What you get
I am writing to apply for your summer finance internship. My cumulative GPA is 3.1, which is below what your posting asks for, and I would rather explain that in the first paragraph than have it be the reason you stop reading: I switched into finance from biology, and my GPA over the last three semesters is 3.7.
The work since that switch is what I would point to. I have completed coursework in Excel modeling, including DCF and three-statement models, and I hold the Bloomberg Market Concepts certificate. As an analyst in our student investment fund I cover two consumer names and have pitched both to the investment committee, which is the closest thing on campus to defending a number in front of people who will push back.
I have also worked 20 hours a week in campus dining for my entire degree, alongside those semesters. I mention it because it is the reason the 3.1 exists and the reason the 3.7 is worth something.
I am available full time this summer and would welcome the chance to talk. Thank you for reading this far.

Career changer applying for an internship after another career
Thirty-four years old, five years in another field, back in school. The unusual fact is the applicant's age relative to the intern pool, so the letter turns it into the reason to hire rather than the thing to explain away.
What you paste
5 yrs restaurant gm, managed 22 staff + 1.4m annual revenue, left to do part time cs degree finishing next yr, python + sql + django, built scheduling app used by 2 restaurants ~40 staff, freecodecamp cert, want swe internship, avail 40 hrs, comfortable on call and with customers escalating
What you get
I am applying for your software engineering internship. I am a part-time computer science student finishing next year, and before this I spent five years as a restaurant general manager running a team of 22 and about $1.4M in annual revenue.
I started programming to solve a problem I had: scheduling. I built a scheduling application in Python and Django with a SQL backend, and it is now used by two restaurants covering roughly 40 staff. Everything I know about deployment, migrations and gathering requirements I learned because those users complained directly to me.
Alongside the degree I completed the freeCodeCamp certification and have kept building. What I bring beyond the coursework is five years of being the person who handles the escalation: I am comfortable on call, comfortable with an unhappy customer, and comfortable saying I do not know yet but here is what I am checking.
I am available 40 hours a week and I am looking for exactly the kind of internship that would be my first engineering role. I would be glad to talk about it. Thank you for your time.

International student who needs work authorization mentioned
The work-authorization question decides whether the application is even eligible, and a recruiter who cannot find the answer moves on. It goes in the closing paragraph in one sentence, in the employer's vocabulary.
What you paste
masters data analytics f-1 visa cpt eligible from may no sponsorship needed for internship, bs statistics home country, r + python + tableau + sql, capstone churn model 15k rows auc .82 team of 3, ta for intro stats 60 students 2 semesters, published dept blog post on survey weighting, avail may-aug
What you get
I am applying for your summer data analytics internship. I am a master's student in data analytics with a BS in Statistics, and I work daily in R, Python, SQL and Tableau.
My capstone was a customer churn model built with a team of three on a 15,000-row dataset, which reached an AUC of 0.82. My part was the feature work and the validation, and the more useful lesson was how much of the result came from the columns we decided to drop. I have also been a teaching assistant for introductory statistics across two semesters, working with about 60 students, and I wrote a department blog post explaining survey weighting to a non-technical audience.
Explaining a method to someone who does not want the method, only the answer, is the part of analytics work I most enjoy, and it is what a teaching assistant does twice a week.
I am available from May through August. I am on an F-1 visa and eligible to work on CPT for this internship, so no sponsorship is required. I would welcome the chance to discuss the role. Thank you for your consideration.

Internships are hired on trajectory, not track record
Every applicant for an internship is short on experience — that is the definition of the thing. So the reader is not comparing your work history against a senior hire; they are comparing you against other students, and deciding which of you will be useful in eight weeks and pleasant to sit near.
That changes what belongs in the letter. Coursework, a club role, a class project, a part-time job in an unrelated field, and something you built for yourself all count as evidence, and they count in roughly that ascending order of usefulness: anything you made or ran, where somebody else depended on the result, outranks anything you merely studied.
A structure that works when you have no experience yet
Under 300 words. Recruiters screening an internship pipeline are reading hundreds of these, and brevity is itself a signal that you can prioritise.
- Paragraph 1 — the internship by name and term (summer, fall, the exact posting title), your year and major, and one sentence of why this team specifically.
- Paragraph 2 — the closest thing you have to the work: a project, a club role, a job. Name the tools, the scale, and what you personally did as opposed to what the group did.
- Paragraph 3 — the second piece of evidence, ideally different in kind from the first: a job that shows reliability if paragraph 2 was academic, or a class result if paragraph 2 was a job.
- Paragraph 4 — availability with dates, work authorization if it is a question, and a request for a conversation.
The five objections, and how to answer each in the letter
- No work experience — do not say you have none. Say what you have done: the club account you grew, the app you built, the survey you ran, the shift you covered for two years. Every one of those is experience with a different label.
- A GPA below the posted cutoff — state the number and the trend in the same sentence if the trend is good, then move on. Hiding it costs you the paragraph anyway, because the reader finds it on the transcript.
- A major that does not match — name the overlap in concrete terms, not as an assertion of transferability. Statistics coursework, a spreadsheet model, a lab writeup: the artefact travels, the claim does not.
- Older than the usual intern pool — treat it as an asset and say why in one sentence: you have managed people, met payroll, handled escalations. Do not apologize for the timeline.
- Work authorization — one sentence, in the closing paragraph, using the employer's vocabulary (CPT, OPT, no sponsorship required for this internship). A recruiter who cannot find this answer assumes the expensive case.
Turning coursework into something a reader can weigh
The difference between a letter that reads as thin and one that does not is almost always specificity about scale and role. "Completed a group project in data analysis" and "built a churn model with a team of three on a 15,000-row dataset, where my part was the feature work and the validation" describe the same semester.
For anything academic, give three facts: what it was, how big it was, and which part was yours. For anything you built on your own, add who used it. A tool with two real users beats a class assignment with a perfect grade, because it survived contact with someone who did not have to be polite about it.
Where internship letters go wrong
- Opening with "I am writing to express my strong interest in". It says nothing and it is the first line of a third of the pile.
- Explaining what the company does back to the company. One specific sentence about why this team is worth a hundred words of their own website quoted at them.
- A whole paragraph on passion. Enthusiasm is assumed for an internship; evidence is not.
- Leaving availability out. Dates and hours are load-bearing facts for an internship and their absence produces an email that could have been avoided.
- Sending the same letter to twenty postings. The pattern is visible from the first line, and the marginal cost of a real first paragraph is five minutes.
Frequently asked questions
How long should an internship cover letter be?
Under 300 words, three or four short paragraphs, one page. Recruiters screen internship applications in bulk, and a short letter that answers the obvious questions beats a long one that circles them.
What do I write if I have no work experience at all?
Write about what you have done rather than where you have been employed: a class project with its real scale, a club role with a result, something you built and someone used, a part-time job in an unrelated field that shows you turn up. Never open with the words "although I have no experience".
Should I mention my GPA?
Mention it if it is strong, or if it is weak and the trend is good — "3.1 cumulative, 3.7 over the last three semesters" is a sentence worth spending. If it is weak with no trend, leave it out of the letter; it is on your transcript and the letter is not where you want that conversation.
Do I need a cover letter if the application says optional?
Write one. In an internship pool where most applicants skip the optional letter, submitting a specific one is the cheapest differentiation available, and it is the only place you get to explain a switch, a gap, or a GPA.
How do I mention visa status or work authorization?
One sentence in the closing paragraph, in the employer's own terms — for example that you are F-1 and CPT-eligible for the internship term with no sponsorship required. It is an eligibility fact, not a weakness, and leaving it unanswered is what costs applications.
Should I say when I am available?
Yes, with dates and hours: "available May through August, 40 hours a week". Internship scheduling is the recruiter's actual problem, and answering it in the letter removes a round of email.
Does this generator write the letter for me?
It writes a first draft from the notes you paste, using only the facts you give it — it will not invent a project, a GPA, or an employer. Paste the rough version, including the awkward parts, and edit the draft it returns.
