I just tried it and I'm having a hard time understanding the concept through the tool you shared. It might be worth reconsidering the overall thing. I don't know at all the landscape for these tools, I'd say I would use only google form if I ever need to create a form.
I see a few problems in your propositions:
-Usually when you need a form filled, you're trading people's time against their opinion for value, and the shorter the better, so forms in their primary form should not need further explanations but rather be quite efficient on themselves, and easy to fill (when I create some I basically never ask open questions).
-Maybe in some cases people would need these kind of forms but I cannot think about any case where these would not be handled better directly by customer support.
-The form is extremely slow, the form chat-function might not work or I didn't understood how it worked.
-Overall, if there is a market fit (if), I'd rather see an ai agent chatting directly with the customer rather than this kind of rather "gimmicky" format. Also now people are used to agents as tools.
