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.
- Prices you can read first. Every rate, limit and extra charge is on our pricing page, in rupees. Start online with 50 free calls or 50 minutes, before you talk to anyone.
- 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.
- 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.
Synthflow also lists a hand-over with a brief, evaluations and a Test Center, so test those side by side.14
On a trial
Questions to ask, of both of us.
- Do you sell to a business calling only in India, and which number do my calls come from?
- What is the smallest annual agreement, and what happens if volume falls?
- Make a Hinglish call on a poor line, then interrupt the agent. Does it stop and follow you?
- Make the agent hand over to a person. Does the person know what was said before they speak?
- Who checks numbers against the national Do-Not-Call registry: you or the product?
- What is charged on a call nobody answers, and on a voicemail?
- Where are recordings and transcripts processed, and how long are they kept?
