The cover letter is the part of a job application most people dread — a blank page, a job you want, and the pressure to sound confident but not arrogant. ChatGPT is genuinely good at getting you from blank page to a solid draft in minutes. The trick is using it as a drafting partner, not a ghostwriter: the letter still has to sound like you. Here is the step-by-step way to do that.
Why AI helps here (and where it hurts)
AI is excellent at structure, phrasing, and turning your rough notes into clean paragraphs. Where it hurts is when people paste in a job description, take the generic result, and send it — producing exactly the bland letter recruiters skim past. The fix is feeding it your specifics and editing the result. Do that and it is a real advantage.
Step 1: Gather your raw material
Before you prompt anything, get these to hand:
- The job description — the actual posting, so the AI can match your letter to what they asked for.
- Your CV or a list of relevant experience — real achievements, not vague duties.
- One or two specifics about why you want this job at this company. This is what makes a letter feel genuine.
Step 2: The prompt that works
Vague prompts get vague letters. Use something like this, filling in the brackets:
You are helping me write a cover letter for a [job title] role at [company]. Here is the job description: [paste]. Here is my relevant experience: [paste CV or bullet points]. Write a concise cover letter (under one page, around 300 words) that connects my experience to what this role needs. Tone: professional but warm and human, not stiff or clichéd. Do not invent any experience I have not listed.
That last line matters — it stops the AI from inventing achievements, which is both dishonest and easy for interviewers to catch. For more on writing prompts like this, see our guide to good prompts.

The first draft is a starting point, never the final. Talk back to it: “make the opening less generic,” “this paragraph sounds stiff — rewrite it how I’d actually speak,” “cut this to three sentences.” Two or three rounds of this is where a template becomes your letter. If it keeps sounding formal, paste a few sentences you have written naturally and say “match this voice.”
Step 4: The final human check
Before it goes anywhere, read every line yourself and confirm: every claim is true and matches your CV, the company name and role are correct throughout (AI sometimes slips), and it sounds like something you would actually say out loud. Never trust AI with facts unchecked — including dates and details about the company.
Common mistakes to avoid
- Sending the first draft. The generic version is the one recruiters ignore. Always refine.
- Letting it invent things. Tell it explicitly not to add experience you do not have.
- Forgetting to swap details. Check the company name is right everywhere — a leftover placeholder is an instant rejection.
- Losing your voice. If it does not sound like you, keep editing until it does.
Frequently asked questions
They can usually spot an unedited, generic AI letter — they read hundreds. What they cannot spot is a letter you drafted with AI and then edited into your own voice with your real specifics. The editing is what matters.
Using it to structure and phrase your genuine experience is no different from using a template or asking a friend to proofread. It becomes dishonest only if you let it invent achievements you do not have.
Never let it fabricate experience, qualifications, or results. Besides being dishonest, it falls apart the moment an interviewer asks about it. Give it only real material to work from.
No. The free tier writes cover letters perfectly well. Paid plans add speed and newer models, but they are not necessary for this task.
