AI Detector for Cover Letters
Updated
An AI detector for cover letters helps in two directions: job seekers checking that their letter sounds like them, and recruiters looking for letters that read like a template. Paste a letter of 300 words or more to get a probability score with the flagged sentences highlighted.

Length Matters for an AI Detector for Cover Letters
The detector needs at least 300 words. Many cover letters are close to that length, and some are shorter. If yours is under the minimum, the check won't run; that is a deliberate limit, because very short texts give unreliable results.
Don't pad a letter to reach the minimum. Check the letter together with a longer piece of your writing, such as a personal statement, only if both are entirely yours.
For Job Seekers
- Look at the flagged sentences: they are usually the generic ones: "I am excited to apply", "I am a highly motivated team player".
- Add specifics: name the company, the role and one concrete result you achieved; generic letters read as AI whoever wrote them.
- Keep your voice: if an AI tool helped, rewrite its suggestions in your own words rather than pasting them.
- Check the facts: AI-written letters sometimes invent skills or numbers; make sure every claim is true.
For Recruiters and Hiring Managers
A high score on a cover letter is weak evidence. Formal business letters follow conventions, and many candidates use grammar tools or templates. Judging applicants on a detector score risks rejecting good people for writing politely.
If AI use matters for the role, say so in the job ad and ask for something harder to generate, such as a short answer to a question specific to your company.
