ChatGPT Cover Letter: Write One From a Job Posting

Most cover letters fail in the first two lines. "I am writing to apply for the position of…" followed by "I am a hardworking, passionate team player…" tells the reader nothing they didn't already know, and they move on. AI has made this worse: thousands of applicants now send the same polished but empty letter, and recruiters can spot it instantly.

A good cover letter, whether you write it alone or draft a ChatGPT cover letter and edit it, does one job: it connects what the employer needs to evidence that you can deliver it, in a voice that sounds like a real person. It should be short enough to read in under a minute.

By the end of this workflow, you'll have a tailored cover letter of about 250 to 350 words, built from the job posting and your real achievements, edited so it sounds like you.

The Shape of a Strong Cover Letter

Keep it to four short paragraphs:

1. Opening: the role, and one specific reason you're a strong fit or genuinely interested.

2. Evidence: two or three achievements that match the employer's top needs.

3. Fit: why this company or team, in one or two specific sentences.

4. Close: a confident, simple sign-off and availability.

Skip anything that just repeats your CV line by line. The letter should explain why your experience matters for this role.

When You Don't Need One

If an application says a cover letter is optional and you're short on time, a strong tailored CV matters more. But for competitive roles, graduate schemes and career changes, a good letter can be the difference.

1. Find what the employer cares about most

Read this job posting and list the 3 most important needs this employer has, in order.
For each, quote the phrase from the posting that shows it matters. Then tell me anything
about the company or team I should mention to show genuine interest: [paste job posting]

Checkpoint: You know the top three needs and something specific about the employer.

2. Match your evidence to each need

Here is my CV: [paste CV]. For each of the 3 needs above, find my strongest piece of real
evidence: an achievement, project or result. If I have nothing strong for a need, say so
rather than stretching. Don't write the letter yet.

If your bullets are vague, run Resume Bullet Points: Turn Duties Into Achievements first. Strong evidence makes strong letters.

Checkpoint: You have one real achievement for each of the employer's top needs.

3. Teach AI your voice

Paste a cover letter, email or LinkedIn post you've written that sounds like you.

Here's an example of my writing: [paste]. Describe my tone and style in 3 bullet points
so you can match it. Note any phrases I use that you should keep.

Checkpoint: AI has a short description of your writing style.

4. Draft the letter

Write a cover letter for [job title] at [company] using the 4-paragraph structure:
opening with one specific reason I fit, evidence matching the 3 needs, why this company,
and a short close. Use only my evidence above. Match my writing style. Keep it under
320 words. Do not use these phrases: "I am writing to apply", "hardworking",
"passionate", "team player", "I believe I would be a great fit", "dynamic".

Checkpoint: You have a first draft under 320 words.

5. Cut the generic lines

Go through this cover letter line by line. Highlight any sentence that could appear in
anyone's cover letter for any job, and suggest a more specific replacement using my real
evidence, or suggest deleting it: [paste draft]

Then read the letter aloud. Change anything you wouldn't naturally say.

Checkpoint: Every sentence says something specific about you or this job.

6. Final checks and format

• Correct company name, job title and hiring manager's name if known

• Your phone number and email

• No claims that aren't in your CV or that you can't explain

• A plain format, saved as a PDF unless the employer asks otherwise

Checkpoint: The letter is accurate, formatted and ready to send.

A Worked Example

Emeka is applying for a junior data analyst role at a logistics company in Lagos. The posting stresses Excel and SQL, turning data into clear reports for managers, and improving delivery performance.

Generic opening (before): "I am writing to apply for the Junior Data Analyst position. I am a hardworking and passionate graduate with strong analytical skills."

Specific opening (after): "When I analysed six months of delivery data during my NYSC placement, I found that one route caused nearly a third of all late deliveries. That project is why I'm applying for your Junior Data Analyst role: I want to keep turning data into decisions that get parcels to people on time."

The evidence paragraph then links his SQL and Excel reporting work to the posting's needs, and the fit paragraph mentions the company's recent expansion to new cities, taken from the posting.

Expected output

A cover letter of 250 to 350 words that opens with something specific, proves fit with two or three real achievements, explains why this employer, and sounds like you wrote it.

Check Your Work

• Does the first sentence say something only you could say?

• Does each evidence point match a need from the posting?

• Is there one specific reason you want this employer?

• Is it under 350 words?

• Is every claim true and in your CV?

• Does it sound like you when read aloud?

Common mistakes

• Starting with "I am writing to apply for…"

• Repeating the CV instead of connecting it to the employer's needs

• Sending the same letter to every employer with only the name changed

• Letting AI add enthusiasm words that sound fake

• Writing more than one page

FAQ

Do recruiters still read cover letters?

Many do, especially for graduate roles, competitive jobs and career changes. A short, specific letter helps; a generic one rarely does.

How long should a cover letter be?

About 250 to 350 words: four short paragraphs that fit on less than one page.

Can employers tell if AI wrote my cover letter?

Generic AI letters are easy to spot. Using your real evidence, your own voice and specific details makes the letter clearly yours.

Should I address it to a specific person?

If the posting or company website names the hiring manager, yes. Otherwise, "Dear Hiring Manager" is fine.
