Chatbase vs Retell AI: buying questions

How should I compare Chatbase and Retell AI pricing?

Chatbase: Subscription with monthly message-credit and member allowances. Standard adds voice, telephony, helpdesk and API access. Auto-recharge is $40 per 1,000 message credits; extra agents cost $25/month and branding removal $99/month. Model choice affects credit use. 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. 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.

Can Chatbase and Retell AI use my existing knowledge?

The recorded sources for Chatbase include URLs; sitemaps; PDFs; documents; tickets. For Retell AI, they include prompts; documents/knowledge bases; API tools; 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.

What should I test in a Chatbase vs Retell AI pilot?

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: Chatbase: Credits, custom-domain, branding and advanced features can be add-ons; model total cost at volume. Retell AI: Telephony, model, speech and other provider costs may be separate; technical integration work is expected.
