I've only used it for a few projects but it's now my go to tool for onboarding and product demos. I'm not going into the list of features as that depends on which level you buy into.
What I can say is it knocks all the competitors out of the water. Some not naming names, own onboarding is so bad I gave up trying to use them. Not so with Fable. Straight out of the box you can start working. Intuitive and clear instructions. Decent choice of quality voiceovers or textual dialogue for each step shown.
