DOCX·TRACKED CHANGES·IN YOUR BROWSER
Drop two Word documents. Get a perfect redline.
Jubarte compares two .docx files and produces a real Word redline —
insertions, deletions, moves and format changes — that opens clean in Microsoft
Word. The comparison runs as WebAssembly inside this page, so your documents never
leave your machine.

/ HOW IT WORKS
Nothing is uploaded
The comparison engine is the same Rust core that ships in the desktop app, compiled to WebAssembly and run inside this tab. Your documents are read by JavaScript in your own browser and never sent to a server — the privacy policy says so in writing.

A real Word redline
Not a diff view or a PDF overlay. You get a .docx with genuine tracked revisions that Word can accept, reject, and filter by author — insertions, deletions, moves and formatting changes alike.

The first five redlines are free, with no account and no card. After that, get in touch — most people who arrive here have a recurring document problem worth a conversation rather than a subscription.

Are my documents uploaded to a server?

What do I get back?
A .docx file with genuine Word tracked revisions — insertions, deletions, moves and formatting changes — that Microsoft Word can accept, reject, and filter by author.
