AI Cover Letter Writer — Free Online Tool

The AI Cover Letter Writer produces a tailored cover letter from your background and the job posting, structured to the format recruiters expect.

Tailoring is the entire value, because the alternative — one letter sent everywhere with the company name swapped — is transparently obvious to anyone who reads applications for a living. Feeding the tool the actual job posting rather than a job title lets the letter mirror the language the employer used, which matters both to the human reader and to applicant tracking systems that screen on keyword overlap before a person sees anything.

What to add after generating, without exception: something specific about this employer that could not appear in any other letter. A product you have used, a recent announcement, a problem the team has described publicly, a person whose work you know. Ten minutes of reading produces a sentence that immediately distinguishes the letter from every templated application in the pile, and no amount of polishing the rest substitutes for it.

What to cut: the generic enthusiasm. "I am excited to apply for this opportunity at your esteemed organisation" is the opening of a large fraction of the letters a recruiter reads that day, and it communicates nothing. Opening with the concrete reason you are a fit for this specific role is stronger and shorter.

Keep it to one page. The letter's job is to make someone read the CV, not to duplicate it.

Your details are sent to an AI model to generate the letter and are not retained.
