Check your cover letter for AI fingerprints before you hit send
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.

Academic proofreading, plagiarism checking and AI-powered writing tools in one place
A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
