A generic cover letter gets skimmed past in seconds, and the reason is usually the same: it talks about what you want instead of what the hiring manager gets. These five prompts force the letter to be specific, short, and aimed at one job.
What’s on this page
- An opening line that names the role and one concrete reason you fit.
- A prompt that turns messy notes into two proof paragraphs.
- How to mirror the job ad’s own wording without sounding like a copy-paste bot.
- A tightening pass that cuts the letter by roughly a third.
- A final check for tone and the details people get wrong.
The prompts
1. Cover Letter Opener
Act as a hiring manager at [company] reviewing applications for [job title]. Write the opening paragraph of a cover letter that names the role, states one concrete reason I am a strong fit, and avoids every generic phrase. Keep it under 60 words. My background: [one line about your experience].What it does: Replaces “I am writing to express my interest” with an opener that earns the second sentence.
How to use: Replace [company] and [job title], then paste a real one-line summary of your experience. Add the job ad text if you want the wording to echo theirs.
2. Job Ad Decoder
Here is a job ad: [paste job ad]. List the five things this employer actually cares about most, in order. For each one, name the evidence a candidate should show to prove it.What it does: Turns a wall of requirements into a ranked list of what you have to prove.
How to use: Paste the full ad including the “about us” section. Use the top three items as the backbone of your letter.
3. Proof Paragraph Builder
Write two short paragraphs for a [job title] cover letter. Each paragraph must describe one thing I did, the result it produced, and why that matters for [company]. Use my notes: [paste rough notes about your work]. Do not invent numbers — if a metric is missing, write "result" instead.What it does: Converts rough bullet points into evidence paragraphs and refuses to make up metrics.
How to use: Dump bullet points, not polished sentences. Add real numbers wherever you have them, and delete the word “result” afterwards.
4. Why This Company
Write one paragraph explaining why [company] specifically, based on this information: [paste what you found about the company — product, recent announcement, stated values]. Reference one detail only, and connect it to a problem I can help solve as a [job title].What it does: Makes the “why us” paragraph concrete instead of flattering.
How to use: Paste something real — a product page, a launch note, a line from the posting. If you found nothing real, drop this paragraph instead of faking it.
5. Tightening Pass
Rewrite this cover letter so it is 30 percent shorter without losing any facts. Remove every sentence that does not either prove a skill or answer "why this company". Flag anything that reads as filler. Letter: [paste your draft].What it does: Cuts the letter down and points at the filler instead of hiding it.
How to use: Run this after your draft is done, not before. Then delete the flagged sentences rather than rewriting them.
How to adapt these prompts
- Use your own variable names — [job title], [company], [years of experience] — so the model stops asking vague follow-ups.
- Changing careers? Add one line to prompt 3: “Frame the evidence as transferable rather than as a list of past duties.”
- Run each prompt in a fresh chat, so your earlier draft does not bias the output.
FAQ
Do you still need a cover letter?
Plenty of postings make it optional. Write one when the ad asks for it, or when you have a specific reason for the move that a resume cannot show.
Should ChatGPT write the whole letter?
Use it to structure, prove and tighten. The facts and the voice have to be yours, because you are the one who will be asked about them in the interview.
How long should it be?
One page, three or four paragraphs. If it runs longer, prompt 5 will find the sentences to cut.
