Retell AI Alternative: Adya vs Retell
Retell prices every part of a call separately — voice engine, model, voice, telephony and add-ons. Adya charges one rupee rate. Here is how the two compare for a business in India.
What is Retell AI, and how is Adya different?
Retell AI charges $0.055 a minute for its voice infrastructure, plus the LLM, text-to-speech and telephony you pick, for $0.07–0.31 a minute in total. Its own example is $0.11 a minute. It includes 20 concurrent calls, sells extra concurrency at $8 a line, and is SOC 2 certified.
Adya is one AI agent for phone calls, website chat, WhatsApp and email, at ₹6 a minute with telephony included and a free plan to start.
Choose Adya if…
- You want rupee pricing with telephony and an Indian number included
- WhatsApp and email need the same agent as your phone line
- Your support team, not engineers, will run the agent
- You want human takeover in a shared inbox out of the box
Choose Retell AI if…
- You need SOC 2 certification today
- You want to choose the LLM per agent, from GPT to Claude to Gemini
- You run high concurrency and want 20 lines included
- Your customers are mainly in the US

Retell AI vs Adya: FAQs
As of 12 October 2026 Retell lists voice agents at $0.07–0.31 a minute: $0.055 for its voice infrastructure plus the LLM, voice and telephony you choose. Its calculator example comes to $0.11 a minute.
For an Indian business they land close. 1,000 minutes on Retell's $0.11 example plus $0.015 telephony is about $125, or ₹11,500 at ₹92 to the dollar. Adya Growth is ₹10,999 for the same minutes with telephony, an Indian number and 5,000 chat conversations included.
Retell's pricing page lists voice agents and chat agents, not a WhatsApp agent. Adya answers WhatsApp, website chat, email and phone calls with one agent.
Retell describes itself as SOC 2 certified and HIPAA-ready, with a BAA on Enterprise. Adya does not hold SOC 2 yet; it aligns with India's DPDP Act and publishes its security practices and subprocessors.
Retell includes 20 concurrent calls and sells more at $8 per line per month. On Adya, talk to us about concurrency for campaign volumes; Enterprise plans carry custom quotas.
