About Vaani AI

Vaani is a voice AI agent platform from Vaani AI Research Pvt Ltd, with offices in Bangalore, India and Singapore. Teams build agents that make and answer phone or web calls, use a knowledge base, transfer to humans and send extracted fields and a call disposition back to your app.

Teacher AI drafts an agent from a plain-language brief and shows changes as a prompt diff. Agents remember past callers, screen calls, detect voicemail and do warm or live transfers. Developers trigger calls through a REST API, run scheduled campaigns, embed in-app voice and receive call_ended and call_postprocessing webhooks. You pick the LLM, speech-to-text, voice and carrier from providers such as OpenAI, Gemini, Groq, Deepgram, Cartesia and Twilio. Pay as you go adds a per-minute platform fee to those component costs; Enterprise adds your own keys and white-label.

It fits developers and Indian businesses running outbound sales, admissions or support calls, including Hindi and Hinglish. Voiceflow is stronger for designing chat and voice flows across channels, SESTEK and Yellow.ai suit large contact centers that want a managed enterprise vendor, and Vapi or Retell AI are the closest developer-first rivals. Per-call cost depends on the stack you choose, so budgeting takes some work.

Vaani launched its Developer Platform on Product Hunt on October 30, 2026 and finished #1 of the day. Buying tip: use the cost estimator on the pricing page with your own call volume and model mix, because voice synthesis can cost more per minute than the $0.02 platform fee.

Our take

Vaani is a credible developer-first voice agent platform, especially for Indian languages and outbound calling, with pricing that is unusually open. Model your real call volume in the estimator before committing, and move to Enterprise if you need your own keys or more than a couple of concurrent lines.
