I can use my own data to train bot conversations without having access to large amounts of training examples.
You have all you need in one place when it's time to build your first conversation! It took me some getting used to but now that everything is laid out clearly, building an intent model has been straightforward. The documentation could be better -- there are many sections where things don't seem quite right (e.g., what does this mean?) so take advantage of those links at the bottom of each page so you know how to get back here if needed. Having a single interface makes setting up new users much easier than trying to do multiple interfaces separately.
