Should You Use AI for Your Cover Letter? Where the Line Is

Almost every guide on this subject tells you to use AI for structure and pressure-testing, but never specifies which parts you should finish on your own. The persuasive elements of a cover letter—the specific numbers, projects, and reasons tailored to the company—are the only things AI cannot generate effectively. AI tends to repeat clichés and fails to produce unique, company-specific details.

The key question is whether AI-generated text can be distinguished from human-written material, and the answer is that it can, even if it isn't immediately detectable by detectors. The real danger is not being caught by a detector, but appearing identical to other applicants, which can cost you the job. A quick test to check for this sameness involves highlighting all sentences in your draft that could appear verbatim in another cover letter.

If most of your sentences highlight, you're likely falling into the same trap that AI does, providing generic language rather than personalized experiences. AI can help with structural tasks like extracting requirements from a job description, reordering your bullet points to best fit the job, and trimming your cover letter down to the required word count without losing critical specifics.

However, AI should not be relied upon to invent your achievements or understand the nuances of the company you're applying to. Focus on providing AI with your hard data and let it handle the arrangement and compression, but avoid asking it to generate achievements or company-specific insights. The most effective prompts involve giving AI your raw facts and then asking it to draft a 220-word cover letter that strictly follows those facts, avoiding any generic language or adjectives.

This approach maximizes the chances of creating a cover letter that stands out rather than blends in with the crowd.
