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.
- AssemblyAI (Per Usage) — AssemblyAI bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- 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.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Speech AI platform for developers — long-form audio transcription, speaker diarization, and Universal-2 speech understanding models. Usage-based pricing: Best model at $0.37/hr audio, Nano tier at $0.12/hr. Pay-as-you-go with $50 free credit. Popular with podcast platforms, meeting recorders, and companies building on top of long-form audio.
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.

What each is best for
AssemblyAI is worth it if… developers processing long-form audio at scale — podcasts, recorded meetings, call recordings. The per-hour pricing works out cheaper than Deepgram for batch transcription (as opposed to real-time streaming).
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.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
