CoverSentry

Checking whether your cover letter reads as AI-written before a recruiter does is the job CoverSentry handles.

CoverSentry is an AI detector built specifically for cover letters.

You paste in text or upload a document, and it scans the letter and returns instant results along with recommendations you can act on.

Detection runs on a fine-tuned BERT model, and the site says it does not store what you submit and uses no tracking cookies.

Scans are free.

If the scan flags your draft, CoverSentry also offers a cover letter generation service that aims for human-sounding text.

That part relies on third-party AI providers, though the site says data protection policies apply.

Keep the limits in mind.

No AI detection system is 100% accurate, so think of a score as a signal and not a verdict.

The tool currently supports English only, which rules it out if you apply in other languages.

It is a narrow, single-purpose checker, and that focus is the reason to use it over a general-purpose AI content detector.
