CoverSentry

Check your cover letter for AI fingerprints before you hit send

Instant AI-generated score

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.

Cover-letter-specific model

The scanner was trained on a custom corpus of cover letters rather than generic web text, so it recognises the specific templates applicants reuse.

In-memory privacy-first analysis

The detector stores nothing — documents are analysed in memory and discarded immediately, and the site does not use tracking cookies.

Actionable humanising tips

Each scan returns concrete rewrite suggestions aimed at the phrasing patterns that make letters read as machine-written.
