Universal Editor - Use case Query

Hi,

I am about to implement universal editor service in local aemaacs instance. I have few clarifications on the use cases of universal editor. Is it for editing content at one place and without having to activate/publish the content, the edited changes appear on the site as part of the edge delivery services? Does it also include a special editor like RTE where in universal editor plugins are easy to configure and use? Can someone provide some insights on the use cases of the universal editor with AEMaacs.

Regards,

S
