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. Talkdesk AI: Contact-center licenses plus AI interactions, telephony and other usage, with professional services charged separately where required. Core license commitments follow the order form; usage can be billed monthly. Autopilot and enterprise deployment are likely to require a higher budget than self-serve chatbots; confirm the total with sales. 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 Talkdesk AI, they include knowledge bases; CRM; interaction transcripts; policies; business systems. 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. Talkdesk AI: Phone, AI and recording usage can be separately metered; validate exact edition and carrier costs.
