We’ve already covered the AI tools for resume building. But that’s not the only thing job seekers have to take care of. They also need to prepare cover letters. Both go hand in hand. However, opinions and numbers on this are mixed. Some research shows that 77% of hirers consider cover letters useful for learning more about applicants. Other LinkedIn analyses suggest that 93% of employers don’t even bother to read them. But these conflicting claims are not a reason to treat your job application letters as an afterthought. That’s where AI tools for writing cover letters come in — they help you hit the balance.
Instead of writing the sentence that opens half the cover letters ever submitted, these AI tools focus on proving you’re a real, thoughtful person. And what matters most is that they connect what a candidate has actually done with what an employer is asking for.
Let’s look at the top options that await you!
Top Five Best AI Tools for Writing Cover Letters
Cover Letter Copilot
Cover Letter Copilot does exactly what its name suggests. It emphasizes creating personalized cover letters that work well with automated screening and hiring managers. Besides uploading a resume, users only need to specify the job title and company name and paste the job description.
