Hyper: No-code voice AI agents, now with GPT-Live duplex

Hey Product Hunt, I'm Yam, co-founder and CEO of Hyper.

My co-founder Alexey and I grew up in Afula, a small town in northern Israel. We kept seeing local business owners miss calls, lose leads and struggle with tech that was built for companies with IT teams. So we built Hyper: a no-code platform where anyone can build a voice AI agent for any use case, without writing a line of code.

Today we're launching full support for OpenAI's GPT-Live-1.

Most voice bots work like walkie talkies. You talk, wait, it answers. GPT-Live-1 is full duplex: it listens and speaks at the same time, handles interruptions naturally and keeps the conversation going while it works in the background. It feels like a real phone call.

The catch? Realtime models are amazing in demos but unpredictable on real calls. Background noise, accents, bad connections, people talking over each other. That's why we built HOS, our Hyper Optimization Stack, which makes realtime models consistent enough to put in front of real customers.

What you get with Hyper:

GPT-Live-1 in any workflow, built with our no-code builder

Inbound and outbound calls, WhatsApp and a website widget

70+ languages with automatic language detection

Tool calling and live handoff to a human agent

Model agnostic, bring your own model

Next up: GPT-Live-1.1 support as soon as it lands in OpenAI's API.

Launch gift: the first 5 people to use code FREE1 at checkout get their first month of the Basic plan 100% free (valid until Oct 30).

We'd love your honest feedback. What would you build with a voice agent that sounds human?
