What is Ediphi?

Hey, y'all. Recently joined the estimation trade. This website has been awesome so far, and I've been really enjoying getting to use it and learning how to use it better (including advanced features such as the custom properties).

I did notice that there seems to be some Ediphi related custom properties. I don't remember adding them, and I'm uncertain if they were there to begin with. Googling the website gave me some information, but I don't really have the greatest "big picture" understanding of the industry as a whole given my lack of experience both at the desk and in field.

What is Ediphi about? What is their biggest selling point feature? Would using said software be a total game changer? Etc.

And, after all that, how does it work with zztakeoff?

Thanks for y'all's time with this. If you could keep it more "layman's terms", that'd be awesome. I'm still learning a lot of the more industry specific vocabulary.
