Why you shouldn’t use AI to write your cover letter or resume
In today’s demanding and fast-paced job market, it’s tempting to turn to AI tools for help with the application process, including writing your resume and cover letter. With just a few prompts, these tools can produce clean, professional-sounding documents in seconds. However, while this might seem like a clever shortcut, relying too heavily on AI can be a disadvantage and could negatively impact your chances of getting hired.
Here’s why using AI to write your resume or cover letter can backfire—and what you should do instead.
1. Your tone of voice is not authentic or unique
Your resume and cover letter are your first opportunity to introduce yourself, not just your skills, but your personality, communication style, and values. AI-generated content often lacks the nuances that make your application unique. Hiring managers can usually tell when something feels generic. If your application sounds like it could belong to anyone, it won’t stand out.
2. AI doesn’t know your strengths or key achievements
AI can only work with what you feed it. If you don’t input detailed, specific achievements and responsibilities, it’s likely to default to vague statements like “results-driven professional with a proven track record.” These clichés might sound impressive, but they don’t tell the hiring manager anything meaningful about your actual experience or value. That is only something that you can provide.
3. Trust us: it’s easy to spot and dismiss
Recruiters are becoming increasingly skilled at spotting AI-written content. When they come across resumes or cover letters that feel overly polished, overly generic, or inconsistent with the candidate's actual communication in interviews or emails, red flags go up, and those applicants don’t make it past the initial resume screening process.
4. You miss an opportunity to demonstrate your understanding of the role
A personalised cover letter isn’t just about summarising your experience—it’s a chance to show that you understand the company, the role, and how your background and experience fit. When done right, it demonstrates that you’ve taken time to research, reflect, and communicate strategically.
AI can mimic structure and tone, but it can’t replicate your insight or your motivation. Employers want to see thoughtfulness, curiosity, and alignment, not just buzzwords.
So, what should you do instead? And how can you utilise AI effectively?
Using AI as a supporting tool, not to create content, is key. It’s fine to use it for grammar checks, formatting suggestions, or brainstorming language. But your achievements, your motivation, your story—need to come from you.
Here’s a better approach:
Start with a rough draft in your own words.
Use AI to grammar check, not write your content
Ask for feedback from real people—mentors, friends, or recruitment advisors, not AI
Personalise your content to each role you apply for
Final Thoughts
AI can support your job search, but it shouldn't speak for you. When it comes to your resume and cover letter, authenticity is key. Take the time to write them yourself—your future employer will notice, and you will give yourself the best chance to secure your dream job.
