Is anyone aware of a plugin for MS Word that allows me to keep my documents in a git repository (gitlab compatibility would be even better)? I'm aware that git diffs won't be very meaningful, merges are impractical, etc. with binary file formats; I'm not concerned with any of that. I'd just like to be able to keep a repository of multiple versions in a streamlined manner, without having to manually manage multiple files.

"Track Changes" within Word seems to be intended for collaboration or editing with multiple authors (though of course it doesn't HAVE to be used like that), and at any rate the advantage of using git (especially a git service like gitlab) is that it integrates versioning and backups, which I'd still have to take care of some other way if I used Track Changes.

I can do git manually (via command-line tools) if necessary, but an interface from within Word would be nice.
