Short answer: Yes — Claude writes genuinely good cover letters. Paste the job description, give Claude a few bullet points on why you’re a fit, and it produces a UK-format letter in under a minute. The trick is good prompting: specify the tone, avoid clichés, and don’t let it start with “I am writing to apply for…”
Short version: Claude writes cover letters well, but only if you prompt it properly. The default output is competent but generic ("I am writing to apply for the role of..."). With a bit of direction it produces letters that sound like you, show genuine understanding of the role, and avoid the clichés recruiters have read a thousand times.
This guide covers how to prompt Claude properly, three cover letter situations, and what to avoid.
The best way to prompt Claude for a cover letter
Three inputs make the difference between a generic letter and a strong one:
- The job description — paste the whole thing
- Your CV or a bullet-pointed summary of relevant experience
- Three specific reasons you want this role at this company — not generic reasons, specific ones
Here’s the prompt:
Prompt: "Write a UK-format cover letter for this job: [paste JD]. Here's my CV: [paste CV]. The three specific reasons I want this role at this company are: 1) [specific reason], 2) [specific reason], 3) [specific reason]. Tone: warm, confident, not salesy. Don't open with 'I am writing to apply for'. Don't use any of these clichés: 'passionate', 'results-driven', 'team player', 'go-getter', 'proven track record'. One page maximum. British English."
The anti-cliché list is the magic bit. Without it, Claude will reach for the stock phrases every cover letter uses. With it, Claude writes like a person.
Three cover letter situations
Standard application for an advertised role
Use the prompt above. The specific reasons you want this role matter more than anything else — they prove you’ve read the job description and researched the company.
Speculative letter to a company not currently hiring
Different approach:
Prompt: "Write a speculative cover letter to [company name]. I'm interested in them because [specific reasons]. The sort of role I'd want is [role type]. Here's my CV: [paste]. The letter should: (1) explain clearly why I'm writing even though they haven't advertised, (2) make a specific proposition about the value I'd bring, (3) ask for a conversation, not immediately for a job. Warm, confident. One page. UK English."
Explaining a career change or unusual background
Prompt: "I'm applying for [role] but my background is in [different field]. Here's the JD: [paste]. Here's my CV: [paste]. In the cover letter, address the career-change directly in the first paragraph — don't hide it. Explain what's transferable, why I want to make the change, and what I bring that someone from a traditional background wouldn't. Confident, not apologetic. UK format, one page."
What makes a Claude cover letter good vs generic
Good:
- Opens with something specific, not "I am writing to apply"
- Shows evidence of having read the job description (references specific requirements)
- Shows evidence of having researched the company (names a project, product, or value)
- Uses active verbs, specific achievements, numbers where possible
- Ends with a clear next step ("I'd welcome a conversation about...")
Generic:
- Opens with "I am writing to apply for the position of..."
- Lists generic qualities (passionate, team player, results-driven)
- Could be sent to any company for any role with a few word changes
- Uses passive voice ("I have been involved in...")
- Ends with "I look forward to hearing from you"
If you tell Claude explicitly what to avoid, it avoids it. The default is generic; the prompted version is strong.
What Claude won’t do (and shouldn’t)
- Lie about your experience. If you push it to claim things that aren't true, it'll do it — but you'll get caught at interview. Only ever let Claude work with what's actually on your CV.
- Make an unfit role fit. If you're applying for something you're genuinely not qualified for, no cover letter will fix that. Claude works best when you're a realistic candidate who needs the letter to make the case clearly.
- Produce a styled document. Claude outputs text. Paste into Word or Google Docs, apply a letter template, convert to PDF.
