Why Your AI Cover Letter Sounds Generic, and How to Fix It

Open with proof, not enthusiasm

A cover letter has one job: show that you understand the role and have done something relevant. AI drafts handle the format well and miss the job entirely. They open with "I am writing to express my keen interest", describe you as "a passionate and results-driven professional", and close by saying you would welcome the opportunity to discuss. A recruiter has read that letter many times. This is how to replace it with one they remember.

Start by deleting the first paragraph. In most AI drafts it restates that you are applying, which the recruiter already knows. Open instead with the strongest relevant fact you have. Before: "I am writing to express my keen interest in the Marketing Manager position at your company." After: "I spent the last two years growing a newsletter from a few hundred readers to a list that now drives most of our sign-ups, which is the kind of work your Marketing Manager role describes." Use only facts that are true for you.

Replace adjectives with evidence. "Passionate", "dynamic", "detail-oriented" and "team player" are claims. A recruiter wants the proof behind them. Pick two or three accomplishments from your experience, and for each say what the problem was, what you did and what changed. Use real numbers if you have them, and leave them out if you do not. A made-up figure is worse than none.

Make it specific to the job

Mirror the job posting without copying it. Read the description and find the two or three things it stresses most. Address those directly, in your own words. This shows you read the posting, which generic drafts cannot do, and it helps an applicant tracking system as well as a person.

Show you know the company. One specific sentence about the product, a recent launch or the team's approach does more than a paragraph of praise. If you cannot think of anything specific, spend ten minutes on their website and recent posts. If nothing there interests you, that is useful information about the application.

Polish without changing the facts

Fix the voice. Cut stock phrases, trim connectors, and vary the sentences so the letter sounds like a person. A humanizer can do a first pass, but you should reread every line, because a rewrite should never change a job title, date or claim about what you did. Your accomplishments need to stay exactly as true as you wrote them.

Keep it short. One page is enough, and often half a page is better. AI drafts run long because length looks thorough. If a sentence does not help the reader decide to interview you, cut it.

End with something concrete. Instead of "I would welcome the opportunity to discuss my qualifications", say what you would bring in the first months, or ask a real question about the role. Then sign off simply. The goal is a letter that could only have been written by you, for this job.
