XKit Document Compare
What it is
XKit Document Compare is a free web tool for finding additions, deletions, and edits across Word, PDF, and text files. It presents the original and modified content side by side, using green highlights for additions and red for deletions. Word-by-word comparison is intended to catch small changes within paragraphs. Users can upload files or paste text, and compare DOCX, DOC, text-based PDF, and TXT files, including files in different supported formats. The product page says extraction and processing happen in the browser, using Mammoth.js for Word documents and PDF.js for PDFs; files are not uploaded. The tool compares text rather than formatting: it does not show font, colour, bold, or italic changes, and it does not create redline output. Scanned or image-only PDFs need OCR first. Tables and lists are extracted as text, which may alter their structure, and documents over 100 pages may take longer. Listed uses include contract review, editing, policy updates, academic revisions, translation verification, and proposal comparison.
