To use ChatGPT to write a cover letter, paste the job posting and a summary of your experience into ChatGPT, then ask for a letter under 250 words that names the role, highlights the 2 or 3 most relevant achievements, and asks for an interview. Then edit the names, numbers and tone so it sounds like you before you send it. The whole process takes about 5 minutes.

Below you will find a step-by-step process plus 6 prompts for common situations: applying to a posted job, applying as a new graduate, sending a cold application, and following up after an interview.
What a Good Cover Letter Includes
Know what good looks like before you ask ChatGPT, so you can check its work:
| Section | What it covers | Length |
|---|---|---|
| Subject line (email) | Application: Role – Your Name | 1 line |
| Greeting | The hiring manager’s name if you know it | 1 line |
| Opening | The role you are applying for and where you found it | 1-2 sentences |
| Body | 2-3 strengths that match the job, with numbers | 3-5 sentences |
| Closing | Mention your attached resume, ask for an interview, say thanks | 1-2 sentences |
| Signature | Name, phone, email, LinkedIn or portfolio link | 3-4 lines |
How to Write a Cover Letter with ChatGPT in 4 Steps
- Gather your inputs. Copy the full job posting and jot down 5 to 7 bullet points about your experience, skills and measurable wins. If you have a resume, upload it.
- Write a complete prompt. Give ChatGPT a role (experienced recruiter), a task (write a cover letter), context (the posting plus your background) and a format (under 250 words, with a subject line). Use the templates below.
- Refine. Follow up with “make it sound more natural”, “emphasize my project management experience” or “give me 2 more versions”.
- Check before sending. Verify the company name, role, recipient, phone number and every figure. ChatGPT sometimes adds achievements you do not have, so delete them.
6 ChatGPT Prompts for Cover Letters
1. Applying to a Job Posting
You are a recruiter with 10 years of experience. Using the job posting and my background below, write a cover letter under 250 words with an email subject line. Pick the 3 experiences that best match the requirements and include numbers. Do not add anything I did not provide.
Job posting: [paste here]
My background: [paste here]
2. New Graduate with No Experience
I just graduated in [field] and want to apply for [role] at [company]. I have no formal experience, but I have: [projects, internships, activities, skills]. Write a cover letter under 220 words that highlights how fast I learn and my relevant projects. Humble but confident tone.
3. Cold Application (No Open Role)
Write a short email (under 150 words) to the [department] manager at [company] asking about opportunities for a [role], even though no role is posted. Explain why I am interested in the company: [specific reason], and mention 2 standout experiences: [experiences]. End by suggesting a 15-minute call.
4. Tailor to a Specific Company
Rewrite this cover letter for [company]. Add one sentence showing I understand their product [product] and one sentence linking my experience to their current goal: [goal from their website or news]. Keep it under 250 words.
5. Thank-You Email After an Interview
Write a thank-you email after my interview for [role] with [name] on [date]. Reference one thing we discussed: [topic], and restate my interest. Under 120 words, warm but not over the top.
6. Following Up on an Application
It has been 7 business days since my interview for [role] and I have not heard back. Write a polite follow-up email under 100 words asking about the timeline, without sounding pushy.
A Complete Cover Letter Example
Here is a sample for an accountant with 3 years of experience (a fictional candidate), showing the structure to aim for with prompt 1:
Subject: Application: Senior Accountant – Laura Chen
Dear Hiring Manager,
I am writing to apply for the Senior Accountant role posted on your careers page. With three years of accounting experience at a manufacturing company, I can contribute from day one:
- Prepared annual financial statements and tax filings for a business with $3.5M in revenue.
- Cut the month-end close from 7 to 4 days by standardizing reconciliation in QuickBooks.
- Built Excel models (Pivot Tables, XLOOKUP) to reconcile accounts receivable across 400+ customers.
My resume is attached. I would welcome the chance to discuss how I can support your finance team. Thank you for your time.
It is short, specific and mapped to the job. When you use it, replace every number with your own real results.
Tips to Avoid the “AI Voice”
- Ban clichés in the prompt: add “do not use phrases like ‘passionate’, ‘dynamic environment’ or ‘I am excited to apply’.”
- Add one real detail about the company: a product, project or value you genuinely like. AI cannot know this for you.
- Read it out loud. Rewrite anything you would never say in real life.
- Write a separate letter for each company. Recruiters can spot mass-sent letters.

Frequently Asked Questions
Can employers tell if ChatGPT wrote my cover letter?
If you send it unedited, it often sounds generic and is easy to spot. Once you add real details about yourself and the company and adjust the tone, it reads like any other well-written letter. What matters to employers is that the content is accurate and relevant.
How long should a cover letter be?
Around 200 to 300 words, or 150 to 200 for an application email. Keep the details in your attached resume.
Is it safe to paste my resume into ChatGPT?
Generally yes, but remove your home address and ID numbers first. You can also use Temporary Chat so the conversation is not saved to your history.
Can the free version of ChatGPT write a cover letter?
Yes. Writing a cover letter is a simple task that the free plan handles well. Paid plans only matter if you upload many files or use advanced features often.
Should I use Gemini or Claude instead?
Any of them works. The prompts above work in Gemini and Claude too, so use whichever assistant you know best.
Final Thoughts
Using ChatGPT to write a cover letter gives you a polished draft in minutes, but what makes you stand out is still the real detail about you and the company. Save the 6 prompts above, swap in your information, and always proofread before you hit send. Want to get more out of ChatGPT? Read how to use ChatGPT.
