The Retell AI figures are platform prices. The cost of building, testing and maintaining the agent is not part of them: that work is yours or your developer’s.
Retell AI may fit if you have developers who want to build and run their own voice agent, choose its components, and pay per minute.
Eldris Voice may fit if you want the agent built, trained and maintained for you, with no developers, a monthly fee in pounds and a set number of call minutes.
