For my current product I'm looking for a human-human SMS interface in a browser. Ideally, it should just drop-in and work.
SMSInbox pulls outbound messages directly from Twilio logs and creates an embeddable iframe interface. Does Textit.in offer similar functionality?
I do have other ideas that involve bot replies but have some concerns due to the complexity of the workflows in this product. There are dozens of variables involved.
