Full Yuma AI profile and vendor sources · Checked 2026-09-02
The table below preserves each vendor’s scope and qualifiers. An unlisted feature is unverified here; it is not a claim that the feature is unavailable.
Before you decide
Retell AI: Voice cost combines infrastructure, speech, model, telephony and optional per-minute features. Chat is charged per AI message. Phone numbers cost $2/month; 20 concurrent calls are included, with additional concurrency $8/month each. Use the selected configuration to estimate the monthly bill. Yuma AI: Charges for fully automated resolutions; tickets touched by a human are excluded. The pricing page lists $1.50 per extra resolution on monthly plans, but the base monthly fee is unpublished. Custom integrations and other AI add-ons are quoted separately. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded sources for Retell AI include prompts; documents/knowledge bases; API tools; business systems. For Yuma AI, they include helpdesk tickets; store catalog; orders; policies; macros. Ask each vendor to demonstrate ingestion or live access for the exact system you use, with permissions and refresh behavior. A source missing from this directory is not proof that a vendor cannot support it.
Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Can it cite or restrict answers to approved knowledge? What happens when the agent is uncertain? Which actions can it complete beyond answering? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Retell AI: Telephony, model, speech and other provider costs may be separate; technical integration work is expected. Yuma AI: Sales-led pricing and dependence on an existing helpdesk; confirm supported actions and languages.
