Doc reviewing

Hey guys,

I've encountered a problem for myself that I often need help on my word documents. And it's hard to do via emailing.

For this reason i came up with a solution. You open your document on the browser, share the link and ppl can join and view your word document. Making suggestions within a comment place.

Is there anybody here that could benefit from this solution?

Or could it be a viable SaaS?
Thanks in advance :)
