PRIVATE BY DESIGN
Reading, comparison and exports happen in this browser. There are no document requests, analytics, remote fonts or automatic document storage. Clear or close the tab to release the comparison from this app.
Body paragraphs, headings, basic lists and table cells. Two-file mode uses each document’s revised text. Tracked mode derives original and revised body text from native insertions, deletions, moves and paragraph boundaries.
This is a text comparison, not a Word layout or formatting review. Comments, notes, headers, footers, images, text boxes and equations are outside scope. List numbering can be simplified; merged table cells and advanced revisions have limits. Documents with unsupported structural cell revisions are rejected.
Limits: 10 MB per file, 32 MB expanded ZIP, 4 MB per XML part, 6,000 paragraphs and 350,000 text characters per projection. Broad or complex differences may use whole-paragraph highlighting.
Downloaded comparison reports contain document text. Store them where you would store the original files.
