Vaani is a voice AI platform for building agents that speak on web and phone calls.
Core capabilities
Vaani is described as a voice AI harness for production calls. You describe the agent, including who it should call, what it should say, and what counts as success. The site calls the builder Teacher AI. It says the agent can use realistic voices, switch language, handle turn-taking, and keep memories from earlier calls so the next call does not start from zero. The homepage also describes call screening, where the agent stays on the line through a screening prompt. Case studies on the page are about outbound qualification calls, not about exporting audiobooks.
How to use it
Start from www.vaani.dev. The site links a platform at platform.vaani.dev and a button to start on Vaani's platform. You write a brief, answer the builder's questions, review the prompt diff, and then place web or phone calls. Docs are at docs.vaani.dev.
Who it suits
It suits teams that want a voice agent to place or answer calls, such as first-contact sales or support. It is not a general text-to-speech studio for narration.
Pricing, access and limits
The pricing page is usage-based, with a prepaid wallet and an enterprise option. On the INR view, listed rates included a platform fee of ₹1 per minute, a self-learning voice harness at ₹0.25 per call, warm transfer at ₹0.50 per transfer, a phone number at ₹600 per month, concurrency at ₹2,000 per 5 lines per month, and agents with memory at ₹299 per agent. Several of those lines were marked free under an early launch offer. Enterprise is custom. The page has a USD toggle, but these figures are the INR amounts that were displayed. The homepage says start free, while the pricing page charges the wallet for calls. No ongoing $0 minute allowance was listed.
Frequently asked questions
Is Vaani a text-to-speech app?
It speaks on calls, but the product being sold is a voice-agent platform. There is no separate voice-agent category, so the closest audio category is text to speech.
Do I pay per call?
The pricing page uses a prepaid wallet. Phone calls and some features have per-minute or per-call rates.
