How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Regal AI (Per Usage) — Regal AI bills purely on usage — Custom. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Retell AI (Per Usage) — Retell AI bills purely on usage — PAYG. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Enterprise-grade AI voice agent platform for contact centers. ~$0.20/min all-in based on aggregate data across millions of calls, plus platform and implementation costs. Enterprise-only sales motion — no self-serve tier. Third-party "$29/mo" claims are noise; ignore.
AI voice agent platform. PAYG at $0.07+/min base ($10 free credits, 20 free concurrent calls); real all-in cost $0.13–0.31/min. Enterprise drops to $0.05+/min base rate. Supports GPT-5.x variants and Claude 4.5/4.6 Sonnet; Fast Tier LLM adds 1.5–2× charge for lower latency. Direct competitor to Vapi and Bland AI.

What each is best for
Regal AI is worth it if… contact-center teams processing high call volumes (hundreds of thousands to millions of calls/year) that need enterprise integrations, workforce management fit, and negotiated volume rates. Not the fit if transparent self-serve pricing is a must-have or if call volume is under 100K/year — Vapi or Retell AI ship faster and cost less at that scale.
Retell AI is worth it if… developers who want a slightly more opinionated voice stack than Vapi — bundled defaults that ship faster, with paid unlocks for premium voices and Fast Tier LLM latency. Free credits make prototyping frictionless.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
