The record

Purpose: Compares Word, PDF, and text files to identify additions, deletions, and modifications.
Comparison view: Shows the original and modified documents side by side, with additions highlighted green and deletions red.
Comparison detail: Uses word-by-word comparison to detect small edits within paragraphs.
Input methods: Users can upload files or paste text directly into the tool.
Supported formats: Supports DOCX, DOC, text-based PDF, and TXT files, and can compare documents in different formats.
Text extraction: The page says it uses Mammoth.js for Word files and PDF.js for PDFs to extract text for comparison.
Privacy: The product page says processing happens in the browser and files are not uploaded.
Formatting limit: It compares text content and does not display formatting changes such as fonts, colors, bold, or italics.
Scanned PDF limit: Scanned or image-only PDFs are unsupported because they lack extractable text; OCR is needed first.
Large documents: The page says documents over 100 pages may take longer to process.
Table and list limit: Tables and lists are extracted as text, so their original structure may not be perfectly preserved.
Use cases: The maker lists contract review, content editing, version tracking, policy updates, academic revisions, technical documentation, translation verification, and proposal comparison.
Support: The site lists [email protected] as its support contact.
Maker security statement: XKit's privacy policy says tool inputs, uploaded files, and processed data are not collected or stored, while anonymous website usage information and cookies may be used.
