How to Write a Cover Letter With AI (That Doesn't Sound Like AI)

The problem with most AI cover letters

You can tell an AI-written cover letter a mile away. They open with "I am writing to express my enthusiastic interest in..." They use phrases like "leverage my skills," "dynamic team," and "passion for excellence." And they say almost nothing specific about the company or role.

Hiring managers see hundreds of these. They're not impressive — they're noise.

But here's the thing: the solution isn't to avoid AI. It's to use AI differently.

What AI is actually good at in cover letters

AI is excellent at:

  • Structure — organising your thoughts into a coherent narrative
  • Connecting your experience to the role — drawing lines between your background and the job description that you might not have spotted yourself
  • Filling in gaps — suggesting what to include when you're stuck
  • Editing for clarity — tightening up your prose

AI is bad at:

  • Knowing anything specific about the company you actually care about
  • Capturing your voice
  • Making authentic claims about your motivation

The right process: AI as a first draft, you as the editor

Step 1: Feed it the full context

Don't just paste in your resume and ask for a cover letter. Give the AI your resume AND the job description AND a few notes about why you actually want this role. The more context you provide, the better the output.

Step 2: Read the draft critically

When you get the AI draft, read it as if you're the hiring manager. Ask yourself: does this sound like a real person? Is there anything here that only I could have written? If the answer is no, that's your cue to edit.

Step 3: Replace the generic with the specific

This is the most important step. Go through the draft and find every generic phrase. Then replace it with something specific:

  • Generic: "I am passionate about fintech and innovation."
  • Specific: "I've followed [Company]'s approach to embedded lending since your 2023 Series B — the model of embedding credit decisions at the point of transaction is exactly the kind of infrastructure problem I want to work on."

You can't fake specificity. And that's the point — it signals genuine interest and real research.

Step 4: Add your voice

The AI will write in a neutral, professional tone. That's fine as a starting point, but it's not your voice. Adjust sentence length, add a phrase that sounds like something you'd actually say, and cut anything that feels stiff or unnatural when you read it aloud.

Step 5: Cut ruthlessly

A good cover letter is 3–4 paragraphs, 250–350 words. If the AI gives you 500 words, cut it by 40%. Every sentence should be earning its place.

What a strong cover letter structure looks like

Opening (1 paragraph): Why this specific role at this specific company — be concrete. Don't open with "I am writing to apply for..."

Middle (1–2 paragraphs): Your most relevant experience — pick one or two stories that directly address what the job needs. Don't summarise your CV; expand on the things the CV can't capture.

Closing (1 paragraph): Brief, confident, direct. No "I look forward to hearing from you at your earliest convenience." Try: "Happy to talk through [specific thing] in more detail — [your name]."

The phrases to delete immediately

  • "I am writing to express my interest in..."
  • "I am a passionate and dedicated professional..."
  • "I would be a great fit for this role..."
  • "Please find my resume attached..."
  • "I look forward to hearing from you at your earliest convenience."
  • Anything containing "synergy," "leverage," or "thought leader."

The bottom line

AI can write a perfectly competent cover letter in seconds. But "competent" isn't what gets you interviews. What gets you interviews is a letter that's specific, genuine, and sounds unmistakably like a real person who actually wants this job.

Use AI to get you 70% of the way there. Then put in the 15 minutes to make it yours.
