Learn how concealed document content can affect AI tools and academic-integrity reviews, how to inspect a file, and how to document a concern fairly.
Fundamentals
Learn what a file content inspector checks inside PDF, Word, Excel, and text files, how it differs from antivirus software, and where its evidence has limits.
Students
Check a PDF, Word, Excel, or text assignment for comments, metadata, hidden content, and file mistakes before submitting it.
Check a PDF for invisible text, OCR layers, off-page content, annotations, attachments, and text concealed behind shapes.
