TL;DR
The short version
Vapi is flexible developer middleware for voice — bring your own LLM, text-to-speech and telephony, and wire together exactly the voice product you want with maximum control over each component. TextConvo is the opposite trade-off: voice is one channel inside a complete multi-channel engagement platform that's orchestrated out of the box, so go-to-market teams run campaigns instead of maintaining infrastructure.
