AI Call Studio vs Retell AI
Compiled from public pages on 6 Nov 2026, with where each may suit you better.
The honest summary
Retell AI is a voice agent platform with a dashboard and developer tools, sold by the minute in US dollars, with each model and add-on priced on its own. It lists call simulation, QA, listen-in and hand-over with a brief, so it covers more of the call than a bare API. AI Call Studio is built for India only, in rupees, with your own telecallers working in the same product. If you work across countries or want deep control by code, Retell may suit you better.
We work in India only. If you need other countries, look elsewhere.

| What to compare | AI Call Studio | Retell AI |
|---|---|---|
| What it is | AI calling and your own telecallers in one product, built for India. | “Build, deploy, and manage next-generation AI voice agents.”1 |
| Who it speaks to | Indian teams that make or take business calls, such as sales, support, collections and admissions. | Enterprise, mid-market and startups. Developers are addressed under “Developer friendly”.1 |
| How you buy | Start online with a free trial of 50 calls or 50 minutes, with no card. Then a monthly plan. | Self-serve pay-as-you-go with “$10 in free credits”, or a custom Enterprise plan.2 |
| Published price | Plans from ₹999 a month with included minutes, then from ₹3.5 a minute. GST extra. | “$0.07-$0.31 / min for AI Voice Agents”, by the models you pick, or custom.2 |
| Phone line | Included in the per-minute rate. Your own number is ₹600 a month, and you can start on our shared numbers. | Their calculator shows US telephony at $0.015 a minute and offers India as a choice. No charge on your own SIP trunk.2 |
| Languages | English, Hinglish and 16 Indian languages, each with a status label. What you can use depends on the voice. | “Voice agents can hold conversations in multiple languages.” Their docs list languages by provider.13 |
| Indian languages named | Hindi, Marathi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Punjabi, Odia, Urdu, Assamese, Nepali, Sindhi, Maithili, Konkani. | Their language table lists Hindi, Tamil, Kannada, Marathi and Urdu. Other Indian languages and Hinglish are not listed on it as of 6 Nov 2026.3 |
| Hand-over to a person | From Professional: a person hears a private brief, then joins the same live call. Lower plans can hand over to one number. | “AI agents can brief human agents”, and you can “take over the conversation instantly”.1 |
| Your own staff on it | From Professional: Workspace and desks, where staff dial and take hand-overs. Staff calls are ₹1.5 a minute. | Not listed on their public page as of 6 Nov 2026 |
| Call grading | From Professional: Call QA grades the calls you choose against your scorecard, and flags which a person should hear. | “QA up to 100% of your AI calls.” AI quality assurance is $0.10 a minute after 100 free minutes.12 |
| Testing before live | From Professional: the Simulation Lab rehearses an agent against AI-played customers. No number is dialled. | “Simulate thousands of scenarios, and turn real production calls into regression tests.”1 |
| Where it works | India only. If you need other countries, look elsewhere. | Their calculator offers telephony in countries including the US, India, Canada, Australia and Germany.2 |
| Indian calling rules | Your Do-Not-Call list, a 9am to 9pm IST limit, a spoken notice on recorded calls unless you turn it off, and agents that never claim to be human. Consent, national registry checks and your sector's rules stay your job. | Not listed on their public page as of 6 Nov 2026 |
| Certificates listed | None listed on our site. A DPA is available, and our security page says what we do and do not promise. | “HIPAA, SOC2 Type II, GDPR and ISO 27001.”1 |
| API | From Growth, with webhooks. | “APIs and SDKs that give developers deep programmatic control.”1 |

Where we may fit you better
AI Call Studio may suit you if you want
- AI and your people on one floor. From Professional, your telecallers work in the same product as the AI. They dial from the Workspace, sit on desks, and a supervisor can listen, coach privately or take over. You do not need a second tool for staff calls.
- English, Hinglish and 16 Indian languages, labelled. Hinglish is a language in its own right here. Each language shows its status: 13 established, 3 early, waiting on a real-call and native-speaker check, and 2 in beta. Listen before you decide.
- One rate per minute. One rate covers the phone line, the voice and the AI, by the voice you pick, from ₹3.5 to ₹8.5. Ringing is not charged. A dial nobody answers has a fee of ₹0.88.
- Workflows after the call. Set what happens on its own when a contact arrives, a call ends or is missed, or a customer writes back.
- Built for India, and only India. Rupee prices, IST calling hours and Indian languages. We do not sell outside India, so this is all we work on.
Retell also lists hand-over with a brief, QA and simulation, so test those side by side.1
