The Vaani Developer Platform is a no-code voice AI harness for building and deploying human-sounding voice agents on real phone numbers, websites, apps and WhatsApp. The platform went live with its Product Hunt launch on October 30, 2026; its maker, Vaani AI Research, already ran voice AI work for enterprise customers, but the self-serve Developer Platform is the new launch covered here. This post is based on the official website, checked on October 31, 2026.
Describe the agent, then let it build itself
The build experience centers on “Teacher AI”: the user describes who the agent should call, what it should say and what counts as success, in plain language. The system asks clarifying questions about languages, objections, qualifying criteria and handoffs, then builds the prompt, voice, language mix and tools live, with a readiness score as it goes. Every change produces a prompt diff for review before anything is saved, and existing agents can be refined by chat without starting over.
Built for real phone conversations
Vaani’s differentiators target the pain points of phone calls: zero dead air, natural turn-taking, auto-switching between languages and dialects, and realistic voices with emotional tags. The company quotes a best-in-class p90 latency of around 450ms on its sub-500ms multilingual engine. Every call ends with structured data, agents can reference past calls and shared context from other agents, and enterprise-grade setups include version locks, call analytics and compliance features.
Who it is for
The platform suits businesses that need AI phone agents for sales, support, compliance or operational calls: lead qualification, order support, customer follow-ups and callback booking are the showcased use cases. The site lists enterprise customers across banking, insurance, diagnostics and staffing. A free build environment lets developers prototype before committing to calling volumes.
Pricing
Pricing is usage-based with a prepaid wallet, not a flat subscription. The Pay as you go model charges a platform fee of ₹1 per minute on top of component costs for telephony, speech recognition, AI reasoning and voice synthesis, with unlimited agents and knowledge bases. Phone number rental starts at ₹600 per month and concurrency add-ons are available. An Enterprise tier offers custom terms, bring-your-own-provider keys and whitelabel options. Several advanced features, including the self-learning voice harness and warm transfers, are marked as a free Early Launch Offer at the time of checking. Prices may change, so check the official website for the latest pricing: https://vaani.dev/.
