Why Cover Letters Still Matter

Many job seekers skip cover letters or write generic ones. That is actually an opportunity for you. A well-written, targeted cover letter can set you apart when the competition is close.

AI can help you write a strong first draft in minutes. Your job is to make it sound like you.

What Makes a Great Cover Letter

A strong cover letter does three things:

1. Shows you understand the company and role — not just that you want a job
2. Connects your experience to their needs — with specific examples
3. Ends with a clear next step — usually asking for an interview

It should be short. Three to four paragraphs is ideal. Hiring managers are busy.

Step 1: Gather What You Need

Before writing, collect:

• The job description (copy the full text)
• The company name and what they do
• Your most relevant experience for this role
• One or two specific achievements you want to highlight
• The hiring manager's name if you can find it (check LinkedIn)

Step 2: Write the First Draft with AI

Give the AI as much context as possible. The more detail you provide, the less editing you will need.

Prompt to try:

Write a cover letter for the following job posting. 

Job title: [title]
Company: [company name]
What the company does: [brief description]

Job description highlights:
[paste 3 to 5 key requirements from the posting]

My background:
- [Your most relevant experience]
- [A specific achievement with a number if possible]
- [One skill or quality that fits this role]

Tone: Professional but warm. Not too formal.
Length: 3 to 4 short paragraphs.

Read the output carefully. It will be a solid draft, but it will likely need your personal touch.

Step 3: Personalize It

This is the step most people skip. After AI generates the draft:

• Add a specific detail about the company that shows you did research. For example: "I noticed your team recently launched [product/feature] and I think my experience with [X] would be a strong fit."
• Replace any generic phrases like "I am passionate about..." with something concrete
• Make sure the opening line is not "I am writing to apply for..." — start with something more engaging

Weak opening (generic, gets ignored):

"I am writing to apply for the Marketing Coordinator role at your company. I am a passionate and hardworking professional with strong communication skills."

Strong opening (specific, gets read):

"Your job posting mentioned a focus on growing organic reach through storytelling. That is exactly what I spent the last three years doing at [Company], where our blog grew from 2,000 to 18,000 monthly readers."

The difference is specificity. The strong version shows the hiring manager in the first sentence that you read the posting and have relevant experience.

Step 4: Improve the Tone

If the AI output sounds too stiff or too generic, ask it to adjust:

Rewrite this cover letter to sound more conversational and human. Keep it professional but remove any overly formal phrases.
[paste the draft]

Or if it sounds too casual:

Make this cover letter more polished and professional while keeping it concise.

Step 5: Proofread Before Sending

Before you send any cover letter:

• Read it out loud. If it sounds awkward when spoken, fix it
• Check that the company name and job title are correct (AI sometimes uses placeholders)
• Make sure you did not leave any template brackets like [your name] or [company]
• Use Grammarly or paste it into an AI tool and ask: "Check this for grammar errors and anything that sounds off"

Common Mistakes to Avoid

• Do not send the same letter to every job. Even small customizations make a significant difference.
• Do not start your letter with 'I am writing to apply for...' It is the most common opening hiring managers see and it signals a generic letter.
• Do not let the AI use hollow phrases like 'I am passionate about...' or 'I am a dedicated team player.' Replace those with concrete examples.
• Do not skip proofreading. AI sometimes leaves placeholder brackets like [company name] or [your experience] in the output.
