FAQ
Does it show who made the change?
No, it compares the two states only; use tracked changes in Word for attribution.
Why do tables look flattened?
Cell text is extracted as plain paragraphs, so the table structure is lost.
Are files uploaded?
No, both packages are unpacked locally.
Files never leave your device
Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
