How to Write a Cover Letter Using AI

By Karriero Team·

AI can help you write a cover letter by analyzing the job description and your CV, then generating a personalized draft that highlights your most relevant qualifications. The key is to use AI as a starting point and add your own voice, specific examples, and genuine motivation for the role.

Do Cover Letters Still Matter?

While not every employer requires a cover letter, submitting one when the option exists gives you an edge. A well-written cover letter explains why you're interested in this specific role at this specific company. It fills gaps that a CV can't, like career transitions, relocation motivation, or passion for the company's mission.

The problem is that writing a good cover letter from scratch for every application is time-consuming. This is where AI helps.

How to Use AI for Cover Letter Writing

Start by providing the AI with two inputs: the job description and your CV. The AI identifies the key requirements and maps them to your experience. A good AI tool will generate a draft that opens with a hook, connects your experience to the role, and closes with a clear call to action.

Review the output carefully. Remove generic filler phrases like "I'm passionate about leveraging synergies." Replace them with specific details: the company's recent product launch, a project you led that's directly relevant, or a genuine reason you're drawn to their mission.

Cover Letter Structure That Works

Paragraph 1: What role you're applying for and your single strongest qualification. Paragraph 2: A specific achievement that demonstrates you can do this job well. Paragraph 3: Why this company specifically. Paragraph 4: Brief closing with availability and enthusiasm.

Keep it under 300 words. Hiring managers don't read long cover letters. Every sentence should either demonstrate fit or show genuine interest.

Common Mistakes to Avoid

Don't let AI generate a cover letter that simply restates your CV in prose form. The cover letter should add context and personality. Don't use the same letter for every application. And never submit an AI-generated letter without reading it carefully. AI sometimes hallucinates details or uses awkward phrasing.

Frequently Asked Questions

Can employers tell if a cover letter was written by AI?

Unedited AI cover letters often sound generic and formulaic. If you personalize the output with specific details about the company and your genuine motivation, it will read authentically.

Should I submit a cover letter if it's optional?

Yes, if you can write a good one quickly. A strong cover letter differentiates you from other candidates. With AI assistance, there's little reason to skip it.

How long should a cover letter be?

Under 300 words or about three-quarters of a page. Hiring managers scan quickly. Be concise and make every sentence count.
