From Our Beta Testers

Early feedback from teams who tested Jiin during the private beta launch.

The voice quality blew us away. Our customers couldn't tell it was an AI — the interruption handling made it feel like talking to a real agent.

Rahul K.
Head of Operations, Beta Tester

We replaced our IVR with Jiin in a single afternoon. The latency is so low that conversations feel instant — no awkward pauses whatsoever.

SP
Sneha P.
CTO, Beta Tester

The filler sounds and VAD make it uncanny. We ran 2,000 calls in a week and CSAT scores were higher than our human agents.

We integrate with EnableX, Plivo, and Twilio — supporting both Indian and US phone numbers. You can bring your own number or provision one through our dashboard.
Our agents use state-of-the-art TTS with built-in filler sounds, natural pacing, and emotion. In blind tests during beta, listeners could not distinguish the AI from a human agent.
End-to-end latency is sub-second. Our high-performance pipeline — combining optimized STT, LLM, and TTS — ensures conversations flow without awkward pauses.
Jiin is built on top-notch Speech-to-Text (STT), Text-to-Speech (TTS), Large Language Models (LLMs), and Retrieval-Augmented Generation (RAG) with smooth, high-performance pipelines optimized for real-time voice interaction.
Built-in Voice Activity Detection (VAD) continuously monitors the audio stream. When a caller interrupts, the agent gracefully stops, listens, and responds contextually — just like a human would.
We're currently in private beta. Join our waitlist for early access — waitlist members will be the first to onboard when we launch publicly.
Absolutely. You define the agent's tone, script, knowledge base, and guardrails. The LLM + RAG system adapts dynamically during calls while staying within the boundaries you set.
