Word Online is a great tool for real time collaboration on short, non-critical documents.

But if you have a larger, more critical document that you need to collaborate on with others while retaining control of the content, and you want full transparency into what changed, who changed it and when, then Simul is a better fit for you.

That being said, it’s worth noting that Simul integrates with Word Online. So if you’re using Simul, you can actually open and edit documents in Word Online and when you save them a new version will be created in Simul.

That way, you get the best of both worlds. You get the convenience of Word Online but the powerful version control and collaboration features of Simul.
