The honest take

Which one should you pick?

Pick Octa Voice if…

  • You don't want to pick models — you want a bot that works out of the box for your industry.
  • You want one monthly bill with predictable math.
  • You need voice + chat + SMS + WhatsApp from the same subscription.
  • HIPAA, call recording, live-agent handoff, supervisor console should all be built-in.
  • Your team is 1–20 people, not a platform engineering group.

Pick Retell if…

  • You're building a voice product on their API and want deep control.
  • You want to tune every model knob (voice, LLM, prompt caching).
  • You have the eng bandwidth to own your own ACD, recording retention, and compliance.
  • Your use case is voice-only — no chat, SMS, or WhatsApp needs.
  • Your minute volume is high enough that per-minute PAYG beats our flat tiers.
