COMPARISON
Retell AI is a popular platform for building voice agents yourself, with a no-code dashboard and a solid API. We build and run agents for Indian businesses that don't want to. The difference shows most in three places: who builds, Indian telephony, and what a minute really costs in rupees. Facts below are from Retell's own site and docs.

Retell AI is a US platform to build, test, deploy and monitor voice and chat agents, through a no-code dashboard, a REST API and SDKs. You choose the language model (GPT, Claude or Gemini families) and voices.
For India, Retell has a Hindi page, and its language docs list Hindi, Tamil, Kannada and Marathi, with caveats by speech provider. Its docs say numbers can be bought only for the US and Canada; for India you pay international rates or bring your own SIP carrier.
Retell's pricing page lists $0.07–$0.31 a minute, built from infrastructure ($0.055), voice and language-model costs, billed per second from prepaid credits, with $10 of free credit. Calling India adds $0.15 a minute via Twilio or $0.25 via Telnyx. At about ₹88 to the dollar, that's roughly ₹19–₹40 a minute on Twilio before GST, depending on the model and voice you choose.
Ours: ₹8 a minute down to ₹6.50, all-in, plus 18% GST, in 30-second pulses, with unanswered calls not billed. There is a setup fee (from ₹25,000) because we build the agent for you; Retell has none because you build it. See pricing.
