GigAI Document Comparer
GigAI Document Comparer finds text changes between two documents and marks additions and removals in a redline with color coding.
What GigAI Document Comparer is
GigAI Document Comparer finds text changes between two documents and marks additions and removals in a redline with color coding. It can compare by line or by word, with a live count of changes at the selected level. The two inputs may use different formats; supported files are PDF, DOCX, DOC, RTF, TXT, and Markdown. You can copy the plain-text redline or download the result as a .diff file. Its free plan costs nothing, requires no sign-up, and compares two documents. GigAI says files are processed in the browser and are not uploaded, stored, logged, or transmitted. The tool compares extracted text rather than page appearance, so it does not report changes to fonts, colors, images, tables, or page breaks. Scanned PDFs need OCR before comparison, and extraction from legacy binary DOC files is best-effort; DOCX is described as more reliable.
