What are Retell AI and VoxImplant?

Retell AI logo
Retell AI

Retell AI is a voice AI platform that helps you build, test, and launch AI voice agents that sound natural and humanlike on the phone, instead of stiff menu based systems.

You can build agents with a visual flow builder or simple prompts, then connect them to your phone numbers, CRM, and other tools to handle real calls.

Pricing works on a pay as you go basis, so you only pay for the voice minutes or chat messages you actually use, with a separate custom priced Enterprise plan for bigger teams.

It is built for contact centers, healthcare scheduling, sales outreach, and support teams that need AI to handle high call volumes.
