Voice AI agents that talk to your customers — in your app, on your website, or on the phone

We build real-time voice agents with full business context. They don't just answer questions — they book appointments, process requests, and handle calls end-to-end. Custom voice, custom personality, grounded in your data.

Live example: We built the voice coach for Glow Theory — a real-time AI skincare coach that speaks to users, answers questions about their skin and routine, and can add products to their shelf by voice command. Powered by Gemini Live over WebSocket with ephemeral, single-use tokens.

What you get

  • Real-time voice AI in your app or website — users speak naturally, the agent listens, understands context, and responds instantly with a custom voice.
  • Phone-call agents via Twilio — AI receptionist that answers calls, routes enquiries, takes messages, and books appointments 24/7.
  • Full context awareness: the voice agent knows the customer's history, orders, preferences, and account status before the conversation starts.
  • Action-capable: the voice agent doesn't just talk — it books appointments, updates records, processes requests, and triggers workflows hands-free.
  • Custom voice personality tuned to your brand with ElevenLabs, Google, or OpenAI voices — professional, warm, clinical, or whatever fits your business.

Three ways to deploy voice AI

Pick the mode that fits your business — or combine them.

In-app voice assistant

Embedded in your mobile or web app. Users tap a mic button and speak naturally — the agent processes speech in real-time, has full access to their account context (orders, preferences, history), and can take actions on their behalf. Think Siri, but it actually knows your product.

Example: Glow Theory's Skin Coach: users ask skincare questions by voice, and the AI responds with personalised advice grounded in their scan results, routine, and product shelf — and can add products to their shelf via voice command.

Phone-call agent (Twilio)

An AI agent that answers your business phone line. It greets callers by name (if the number is in your CRM), understands the reason for the call, answers questions from your knowledge base, books appointments, takes messages, and routes complex calls to the right team member.

Example: A dental clinic AI receptionist: answers calls, checks appointment availability, books and confirms slots, sends SMS confirmations, and routes emergency calls to the on-call dentist — all without a human receptionist.

Website voice widget

A voice-enabled chat widget on your website. Visitors can speak instead of typing — great for accessibility, mobile users, and customers who find it easier to explain a problem verbally. The AI responds in text and/or voice.

Example: A real estate agency voice widget: visitors describe what they're looking for — 'three bedroom apartment near the beach, under 800k' — and the AI searches listings and responds with matching properties.
