Co-Founder here. BlitzCompare is a spin-off of our main product at EDITIVE (we're building the "Github for documents").<p>BlitzCompare is not just another diff: The big advantages are:<p>* Understands complex structured documents like .docx
Detects moved sections, even if there are small changes within those sections, which are then highlighted separately.<p>* You can navigate between source and destination of those moves by clicking on them<p>* Formatting is shown as an individual type of change, and what has been modified is shown as a tool-tip<p>=> Upload your own docs or click on the "Show example" button to have a look for yourself.<p>A note regarding PDF: Please be aware that PDF files contain almost no formatting information, sometimes not even text (only images), therefore results with PDF will depend on the quality of the input file.<p>Btw. all uploaded documents are immediately deleted after processing.
Well done. I was working on something similar (diff for formatted html that handles moved sections) and there were a lot of gotchas.<p>I'd love to find a node package for this, if anybody has a suggestion.
