GigAI Document Comparer
What it is
GigAI Document Comparer is a free web tool that finds additions and removals between two documents and displays them as a color-coded redline. It extracts text from PDF, DOCX, DOC, RTF, TXT, and Markdown files, and the two inputs may use different formats. Comparisons can run at line or word level, with live counts of added and removed lines or words. Results can be copied as plain text or downloaded as a .diff file. The product says processing occurs in the browser and files are not uploaded, stored, logged, or transmitted. The tool compares text rather than visual layout, so it does not report changes to fonts, colors, images, tables, or page breaks. Scanned or image-only PDFs need OCR first. Legacy binary DOC extraction is best-effort, while DOCX is described as more reliable. The free plan costs nothing, requires no sign-up, and compares two documents.
