In MSE17 I had the pleasure to meet my fellow All Star 2017 Bastiaan van der Kooij, from CX Builders, and get to know the amazing work he has been doing around Oracle Service Cloud.
One of the coolest things he has developed, is the CX Editor, an inline WYSIWYG editor for knowledge base answers, which allows the authoring of answers directly in the customer portal.
It has all the necessary and key functionality that a knowledge manager or administrator would expect (and has available in the console) but also a whole raft of other cool and very useful features and functions.
For example, it enables users to easily insert custom components like accordions or tab sets, with preview capability, and even provides A/B comparison between updated and original versions.
If you want to know more about it, see the demo:
The CX Editor is available to buy and download on the Oracle Cloud Marketplace. Click here to access. Alternatively, contact Bastiaan at info@cxbuilders.com or visit the CX Builders website to see what other cool add-ins are available for Oracle Service Cloud.

Hey Luis, great to see the CX Editor mentioned here! As of a couple of weeks it is nos fully integrated into the Agent Browser as well, having all the same features within the answer WS of the BUI!
This is great news Bastiaan, looking forward to see it.
