GigAI Document Comparer

What GigAI Document Comparer is

GigAI Document Comparer is a free web tool for finding text changes between two documents. It marks additions and removals in a color-coded redline, with a choice of line-level or word-level comparison and a live count of added and removed lines or words. The two inputs can use different formats: the tool extracts text from PDF, DOCX, DOC, RTF, TXT, and Markdown files. Users can copy the plain-text redline or download the result as a .diff file.

The comparer focuses on text rather than visual layout, so it does not report changes in fonts, colors, images, tables, or page breaks. Scanned or image-only PDFs need OCR first because the tool compares text present in a file. Extraction from older binary DOC files is best-effort; DOCX is described as more reliable. The product says files are processed in the browser and are not uploaded, stored, logged, or transmitted. Its free plan requires no sign-up and compares two documents. The maker describes uses in legal and contract work, writing and editing, software documentation, and study or research.

Who it suits

It suits people who need to compare text in contracts, drafts, documentation, or research materials. Users needing visual layout comparison or OCR for scanned PDFs will need to address those limits first.

Limits

The Free plan compares two documents. Comparisons cover text only; scanned PDFs require OCR first, and legacy DOC extraction is best-effort.

Getting started

1. Open the GigAI Document Comparer website.
2. Choose two documents to compare; they may use different supported formats.
3. Select line or word comparison.
4. Review the color-coded redline and live change count.
5. Copy the plain-text redline or download the .diff file.

Verdict

GigAI Document Comparer provides a focused way to identify additions and removals in document text. It is suited to text comparisons, not visual review of page layout or formatting.
