How to Ask ChatGPT to Write a Cover Letter That Sounds Like You
Short answer: give ChatGPT the job ad, two real results from your resume, one specific reason you want this particular role, and a word limit under 300. Ban the opening "I am writing to express my interest." A short letter that answers what the employer is wondering about works better than a long one that repeats your resume.
Why AI cover letters all sound the same
Ask ChatGPT for "a cover letter for this job" and it fills in the gaps with enthusiasm: "passionate," "thrilled," "dynamic team." Recruiters have read thousands of these, and they can spot them quickly.
What the letter needs from you
- The job ad (full text).
- 2 matching results from your resume, with numbers.
- Your real "why": one specific detail about the company or role.
- One gap to address honestly, if there is one.
- A length limit: 200–300 words.
- Banned phrases: "I am writing to express," "passionate," "thrilled," "team player."
Before and after
Before:
write a cover letter for this marketing job
After:
Write a cover letter under 250 words for the job ad below. Open with why this role in one sentence, using a specific detail from the ad: [detail]. Use these two results that match the ad's top requirements: [result 1 with number], [result 2]. Address this gap honestly in 1–2 sentences: [gap]. Use only facts I've given you. Plain words. No "I am writing to express my interest," "passionate," or "thrilled." Job ad: """[paste]"""
Why it works: the specific opening proves you read the ad, the two results give you evidence instead of adjectives, and naming the gap yourself takes away the recruiter's biggest doubt.
Sound like a person, not a template
Paste a paragraph you've written (an email or a LinkedIn post) and add: "Match the sentence length and tone of this sample."
Quick edits after the first draft
- "Cut 20% without losing the results."
- "Make the first sentence more specific to [company]."
- "Read this as a skeptical hiring manager: what's the weakest line?"
FAQ
Should I tell the employer I used AI? That's up to you. Either way, every claim should be true and in your voice. How long should a cover letter be? Usually under one page. 200–300 words is enough for most roles. Can I reuse one letter? Reuse the structure, but write a new opening and choose the results for each role.
