Build a voice agent that sounds and behaves human without writing a single line of code. Design the call flow, handle objections and edge cases, connect your tools and knowledge base, and go live on a real phone number. Every call ends with clean, structured data.
Hey Product Hunt 👋
I’m Chandra from Vaani, a small voice AI team in Bengaluru.
Voice AI started with great models and only later got applications, so putting an agent on a real phone line still means stitching together speech, an LLM, telephony, tools and retries. We built an internal tool to configure agents without all that glue. Founders, PMs and developers who saw it kept asking for access, so today we’re opening it up.
What you can do, no code:
Design the call flow, including how the agent handles objections, interruptions and edge cases
Give it actions: hold, schedule a callback, hand off to another agent or a human
Connect a knowledge base so it answers from your docs mid-call
Pick a number and go live
After every call, get structured data: extracted fields and a disposition, so you don’t have to read transcripts to know what happened
It also orchestrates multiple models and switches to a backup if one fails mid-call, so one bad response doesn’t wreck the conversation.
We started with languages where data is scarce, which is why “sounds local” matters so much to us. It’s built to work for your customers wherever they are.
What’s the first voice agent you’d build, and what would you expect to break it?
We’ll be in the comments all day.

@chandrashekran_y I'd build a "call my notes" agent.
Call a number, ask what I decided about a project last week, get an answer from my docs without opening five tabs.
What I'd expect to break it: me switching between Hindi and English halfway through, then interrupting to correct a name. That's a pretty normal conversation, but a messy test case.
Also curious about the fallback: if the model switches mid-call, does the new one retain the full context, or does the caller have to repeat themselves?
@maybe_someone_20 We actually built this platform for curious techies like you,
Cant wait to see how your built goes, do share a feedback and love if posssible!
And reg. your question, absolutely, the agent context is preserved independant of the models at play
@chandrashekran_y gotcha, looking forward to that!
@chandrashekran_y How well does Vaani handle interruption and backgrounds noise during real phone conversation????
@amrita_prajapati2 haha, this is a classic problem buddy, more our agents naturally handle, but better, we hand out these control and control to the users, you can control exactly how the agents need to behave.
also, regarding handling background noises, we have build propriety modules that solves for these conditions., would for you to try out and let us know!
How well do you guys handle people switching between hindi, english and regional languages mid-convo, like we naturally do in India?
@nishank_koul haha, this is one of the first problem statements we started out with,
To be very frank, We treat language as a probability n not a setting, Vaani.dev tracks context across turns to predict switches and mixing patterns, or you can lock a languages by config when you need strict control.
Vanni works for the vernacular languages too?
@avirup_sarker Absolutely, Low resource languages is one of our biggest strengths, would love for you to try it and let us know how it goes!
Congratulations Vaani team on the launch. The product looks really promising. I want to know what all use case does the Vaani agent covers also what all integrations does Vaani currently provides.
@vishal_goswami7 Hey Vishal, thanks for the wishes!
We already have close to 150 prebuilt templates - across multiple usecases and languages, so go the templates sections > filter by industry (we have close to 10 of them), and find the best template for yourself!
And reg, the integrations, our platform support a lot of integrations, but you wanna make a custom integration., that's also very much possible!
Do try out these features and let us know how it went!
Can't wait to hear from you!
The handoff to a person is the bit I'd spend time on. The caller shouldn't have to repeat the details they already gave the agent.
@oleksii_sekundant Absolutely, all agents prior to the call handover to the human agent will deliver a summary of all the key points of the calls.. This way the caller never have to repeat anyhing, the human agent can take over from where the agent left!
when the agent calls to an iphone user the screening assistant may respond to the call , leading to a agent to agent conversation and unnecessary cost.
Can we handle this in vaani
@shahid_zaman_a nice one buddy, we actually have cracked it hehe, test it out and let me know how it goes
(Quick secret: We used the oldest trick in the trade to solve it, if you figured what it is, do tell me., )
@chandrashekran_y lemme try the platform
@shahid_zaman_a Absolutely, would love for you to check it out!!!
Don't forget to grab the free credits specific to PH users, the coupon code is PHL1000X
we built the voice AI infrastructure. now it's your turn to break things.
@mohammad_palla2 absolutely, cant wait to see the crazy use cases folks gonna be building on Vaani.dev
