I'm looking for a good one that can integrate with GHL. Synthflow is very easy, but their pricing structure is pretty insane! Air.ai has been supe glitchy for me. The script writer doesn't work, they add a lot of "ums" and sounds really fake all around. Vapi has been the best I've tested so far, but their integration seems pretty nuts. I'm looking for a caller to call leads that come in through an optin form and ask some questions and explain what we do, try to get them to book a call on our calendar. Any suggestions at all? Been spinning my wheels since I started messing with all this stuff last week and feel like I keep on coming up with nothing lol. PS. I really don't like node builders. I like the Idea of being able to refine prompts like in synthflow and vapi
