    Hey HN, Chris here. I have been playfully hacking on a few ideas that leverage some of the latest AI tools (both open-source and proprietary). One in particular seems somewhat useful and is ready for a few more eyeballs. The idea is to make building very capable AI phone agents as easy as creating an online form. We think the ease of production will lead to some interesting enterprise use cases. I'd love your feedback (order a Pizza from Vito in the demo to see how it performs) and in particular your ideas about potential uses. Thanks!
