How to edit an AI cover letter so it doesn't read as generated
To edit an AI cover letter, cut the enthusiastic opener, swap every self-describing adjective for a number or a named result, delete lists of three virtues, check each claim against your resume, and add one sentence about this employer only you could write. The same ten edits work on drafts from ChatGPT, Teal, Rezi, Kickresume or Dreamwork.
By The Enclosure editors Published Updated How we check
The short answer
- First, check facts. AI drafts invent skills, tools and numbers.
- Then cut: the opener, the adjectives, the closing claim, and anything over 350 words.
- Then add one specific line about this job or company.
- Read it aloud. Rewrite any sentence you would not say to the hiring manager in person.
What does an edited AI cover letter look like?
Here is a typical AI first paragraph for a data analyst role, and the same paragraph after the edits below. Struck text is cut; marked text is added. The applicant and employer are invented.
Before and after, marked up
I am thrilled to submit my application for the Data Analyst position at Fernhill Grocers. As a results-driven professional with a passion for data, dedication to excellence, and expertise in analytics, I am confident that I would be an ideal fit for your dynamic team. I'm applying for the Data Analyst role at Fernhill Grocers. Your posting mentions weekly shrink reports across 60 stores; at Calder Pharmacy I built the shrink dashboard our 41 store managers open every Monday, and it cut write-offs by 12% in its first year.
Throughout my career, I have leveraged cutting-edge tools to drive impactful insights and foster cross-functional collaboration. I work in SQL and Looker, and I spend about a day a week with store operations deciding what the numbers should change.
The edited version is shorter, names the employer's own problem, and every claim in it is something the applicant can talk about in an interview.
What are the edits that make an AI cover letter sound human?
These are the ten edits we would make to any AI cover letter draft, in order. The first is about truth; the rest are about voice.
Check every fact against your resume
AI generators fill gaps with plausible claims: a tool you never used, a team size you made up, a percentage from nowhere. Read each sentence and ask whether you could defend it in an interview. Delete anything you could not. This is the one edit that can cost you an offer if you skip it.
Delete the opener and start with the role and one fact
"I am thrilled to apply" and "I am writing to express my interest" appear in almost every generated letter. Replace them with the job title and one detail from the posting, as in the example above.
Turn adjectives into evidence
Find every word that describes you: results-driven, passionate, detail-oriented, dynamic. Replace each with the thing you did that earns it, ideally with a number. "Detail-oriented" becomes "caught a $40,000 billing error in the vendor file".
Break up lists of three
"Passion, dedication and expertise" is a rhythm models fall into. Keep the one item you can prove and delete the other two.
Replace vague verbs with what happened
Leveraged, drove, fostered, spearheaded and streamlined say nothing on their own. Write the actual action: built, wrote, moved, cut, hired, answered.
Add one sentence only you could write
A reason you want this employer that would be false for anyone else: a product you used, a post their engineering team wrote, a store you shop at, a line in the posting that matches a problem you have solved. One sentence is enough.
Cut the closing claim
"I am confident I would be a valuable addition to your team" asks the reader to agree with a conclusion. Replace it with a specific ask and a time you are free.
Cut to 250 to 350 words
Generated letters run long. Cut sentences that restate the resume and any paragraph that makes the same point twice. Our annotated example is under 250 words.
Fix the punctuation tells
Long dashes between clauses, "not only X but also Y", and every paragraph the same length are habits of generated text. Use periods. Vary paragraph length by what each one has to say.
Read it aloud, then reread the names
Rewrite anything you would not say across a desk. Then check the company name, the job title and the hiring manager's name. A company name left over from the last letter is an easy mistake when you reuse a draft, and a hiring manager will notice it.
What should you tell an AI cover letter generator before it writes?
Tell an AI cover letter generator the posting, your resume, the one story you want told, and the limits. A prompt that works in ChatGPT, and in the custom instructions some generators accept:
A prompt to start from
Write a cover letter under 250 words for the job posting below, using only facts from my resume below. Open with the job title and one specific detail from the posting. Tell one story: [the result you want told, with the before and after]. Do not describe me with adjectives. Do not use dashes, lists of three, or the words passionate, thrilled, leverage or dynamic. End with a request for a 20-minute call.
Generators that build from a saved resume, such as Teal and Rezi, already have your facts. You still get the most from them by editing the draft with the list above.
Will an employer's AI detector flag your cover letter?
We did not research employer AI detectors for this page, so we cannot tell you how common they are. What the surveys we cite measure is people: in TopResume's May 2025 survey of 600 US hiring managers, 19.6% said they would reject a candidate for AI-generated materials. Edits two to nine above remove the patterns those readers notice. See do recruiters read cover letters? for the full survey details.
