Before you decide
Regal AI: Not publicly documented Synthflow: Sales-led account pricing scoped to expected usage, telephony, integrations, security, and launch support. 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 knowledge and data sources for Regal AI include Not publicly documented. For Synthflow, they include Not publicly documented. Ask each provider to demonstrate access for the exact systems you use, with permissions, freshness, and failure behavior. A source missing from this directory is not proof that a provider cannot support it.
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Regal AI: Architecture is undisclosed. Outbound consent, suppression, caller identity, pacing, and jurisdiction rules remain buyer responsibilities. Synthflow: Confirm current architecture, availability, call controls, data handling, language coverage, and complete cost in a scoped pilot.
