Beyond the phone line

Two ways to bring the same voice agents into your own mobile app and web journeys.

01 · IN-APP CALLING SDK

Calls customers actually pick up

Drop the VoiceNXT SDK into your mobile app and the AI agent calls customers inside the app — like an Uber driver call — instead of from an unknown number.

Up to 300%higher call pickup rate

Branded, trusted caller screen
Your logo, verified name and agent on the ringer — no more “unknown number” or spam labels.
Context before they answer
Show why you’re calling right on the ringer screen, e.g. “Your EMI of ₹4,250 is due on 5th”.
Same agent, same governance
Runs the same VoiceNXT agents, tools, transcripts and audit as phone calls.

02 · IN-APP VOICE ASSISTANT

Add a floating voice assistant to any app or web journey. Customers just talk — in Hindi, English, Hinglish or 7 more Indic languages — and the assistant guides them, answers questions and completes steps with them.

Guides every step
Walks customers through KYC, onboarding, loan or policy journeys on the screen they are on.
Speaks their language
Understands and replies in Hindi, English, Hinglish + 7 more Indic languages, with live captions.
Fewer drop-offs, fewer tickets
Answers doubts in the moment instead of sending customers to a call centre.
