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.
- Call QA and Intelligence. From Professional, Call QA grades the calls you choose on your own scorecard. From Professional, Intelligence adds up what callers asked and which questions nobody could answer.
- 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.
