CoverSentry is a free web tool that scans a cover letter and estimates how likely it is to read as AI-generated, then gives recommendations for making it sound human. It pairs a fine-tuned detection model with a no-registration CV builder that produces ATS-friendly resumes.
Upload a PDF, DOCX, RTF or TXT file, or paste text, and receive a percentage score with a human, mixed or AI verdict in seconds.
The scanner was trained on a custom corpus of cover letters rather than generic web text, so it recognises the specific templates applicants reuse.
The detector stores nothing — documents are analysed in memory and discarded immediately, and the site does not use tracking cookies.
Each scan returns concrete rewrite suggestions aimed at the phrasing patterns that make letters read as machine-written.
