Our editorial assessment
4.5 / 5Editorial ratingDocument review
AI voice agents · toolkompass.io editorial team · 11/11/2026
A well-documented platform for calling AI agents with a clear usage-based cost structure. Knowledge sources and conversation actions are broad; model choice, telephony and contractual control options determine production operation.
Editorial assessment of the documented software offering. No business relationship disclosed. No hands-on product test or assessment of the company's creditworthiness. The assessment covers publicly documented properties. Usability, reliability and result quality have not been tested in practice.
Fit for the use case40 % weighting
4.5 / 5A knowledge base, appointment booking, transfers and call monitoring suit automated telephone processes. Task breadth is established; actual success rates and safe handoffs to people have not been tested in practice.
Retell AI – official product overview ↗Workflow & integration25 % weighting
4.5 / 5Batch calls, integrations and configurable conversation actions support complete telephone workflows. External credentials and services require setup; the documented connection does not itself guarantee error-free execution.

4.5 / 5Per-minute costs are broken down into infrastructure, voice, model, telephony and add-ons. A calculator supports planning; advertised starting costs should therefore not be understood as a flat final price for every configuration.

4.5 / 5Optional disabling of recording and transcription, custom retention and role permissions are documented. SSO and special contract terms depend on the offering; specific permissions and deletion processes have not been tested in an account.
