It’s an in-house tool built to help us better visualise conversation flows.
If you think of a “Choose your own adventure” book, where your choices send you down different paths, our users can also take different paths depending on the questions they ask to our bot.
With our tool we can see the visual representation of each possible flow from start to finish, with all the options along the way and where they link or lead our users to.
Google docs was unable to give us that same overview, but worked fine for our early prototyping and simple conversation flows.
I hope that explains it somewhat!
