Interesting idea, and the UX of the product itself is really interesting and not something I've seen before. I think it could work really well for the target market. A couple of issues I noticed:

- If you pivot there doesn't seem to be a way to go back. I pivoted at the first step and neither arrow left or arrow up go back to the starting point.

- It would be good to label the pivot with what would prompt you to choose it, for example for the first one something like "Pivot available: wrong person answers"

- The animation of the text is quite distracting. It at least needs an option to change the speed, because it animates slower than I could read, and ideally the option to turn it off. It's also buggy if there are multiple paragraphs in the response; subsequent paragraphs start to animate in even before the previous paragraphs have fully loaded, so you have multiple paragraphs animating at once.
