This tool compares two versions of a Word document and highlights the differences between them, making it easy to spot added, removed, or changed text without manually scanning both files line by line. It is helpful for reviewing contract revisions, tracking edits between drafts, or confirming that a colleague's changes match what was agreed. Both documents are compared locally in your browser rather than being uploaded anywhere.
It highlights inserted, deleted, and modified text between the two versions of the document.
The comparison focuses primarily on text content differences; purely visual formatting changes may not always be flagged.
Yes, the highlighted differences can be exported or saved as a comparison report where supported.
Very large or heavily formatted documents may take a bit longer to process since everything runs on your device rather than a server.
