A cover letter is more than just a formality – it is your first opportunity to make a strong impression. It introduces you to potential employers, highlights your enthusiasm, and connects your experience to the role. But writing one can feel overwhelming, especially when you are applying for multiple jobs.
That is where AI tools like ChatGPT or CoPilot come in. With the right prompts and a bit of guidance, you can create a tailored, professional, and engaging cover letter in minutes. Here is how to make the most of it.
What is a Cover Letter?
A cover letter is a one-page document that accompanies your CV or resume when applying for a job. It is your personal introduction to the employer – an opportunity to explain who you are, what you bring to the table, and why you are interested in the role.
Unlike your CV, which lists your qualifications and experience, a cover letter gives you space to tell your story and how it aligns with that role specifically. It allows you to highlight specific achievements, show enthusiasm, and connect your background to the job you are applying for. If done well, it can help you stand out and make a memorable first impression.
Why Cover Letters Still Matter in 2025
- Even in a world of AI-driven hiring, a well-written cover letter can set you apart. Here is why:
- It is your first impression – A strong opening can grab a hiring manager’s attention before they even look at your CV.
- It shows personality – Your resume lists your skills, your cover letter shows who you are.
- It proves you have done your homework – A tailored letter shows genuine interest in the company and role.
- It connects the dots – You can explain how your experience directly aligns with the job.
What Hiring Managers Want to See
When reviewing cover letters, employers are looking for:
- Personalisation – Address the company and the role directly.
- Clarity – Keep it concise and easy to read.
- Enthusiasm – Show that you are excited about the opportunity.
- Attention to detail – No typos or generic phrases.
- Relevant achievements – Use examples that match the job description.
How ChatGPT Can Help You Write a Better Cover Letter
AI tools like ChatGPT and CoPilot can help you write faster and smarter – but only if you give the right input. Here is how to get the best results.
1. Start with the Right Information
Before you prompt the AI, gather the essentials:
- Your name and contact details.
- The company name and job title
- A copy of the job description
- A few key achievements or skills you want to highlight.
The more specific you are, the more tailored your letter will be.
2. Choose the Right Tone
Ask the AI to match the tone to the company culture. For Example:
- “Write this in a friendly but professional tone.”
- “Make it sound confident and enthusiastic, but not too formal.”
3. Use a Template That Fits Your Industry
AI can generate cover letters for different sectors – whether you are in healthcare, construction, marketing, or IT. Ask for a structure that suits your field.
4. Make it Personal
Once you have a draft, personalise it. Include:
- The hiring managers name (if known)
- A reference to the company’s mission or recent work
- A sentence about why this role excites you.
5. Edit and Polish
AI can get you 80% of the way there – but the final 20% is up to you. Read it aloud, check for flow, and make sure it sounds like you. Always proofread for grammar and clarity.
Common Mistakes to Avoid
- Being too generic: Tailor each letter to the job.
- Repeating your CV: Use the cover letter to add context, not copy-paste.
- Ignoring instructions: Follow any specific directions in the job ad.
- Overusing buzzwords: Keep it clear and human.
- Skipping the edits: Always review what ChatGPT generates.
