Difference between SAC for Office and Analysis for Office SAC Edition

Hi,

Which is the difference between SAC for Office Add-on and Analysis for Office SAC Edition in terms of functionalities and use cases?

I went through the documentation but I can't see any difference apart that they are 2 different tools, but we can do the same with both tools. Maybe I'm missing something. There is something special that we can do with one but not with the other?

Regards,

Cristina
