Newired Editor is the application used to create and edit Journeys and Tips. It's to be installed on the personal computers of everyone who is to be responsible for creating them: trainers, process specialists... each company will have their own designated person or team for that. These people will generally be the most suitable and knowledgeable about the businesses processes and the base application.
Newired editor can be downloaded from Newired Portal and has an internal browser, which allows Journey and Tip authors to see the outcome of what they've created on a stage environment.
On the picture below, we can see the editor to the right and its internal browser to the left:
