Introducing Avatarium: Real-Time AI Avatars for Every App

Today we are launching Avatarium, a platform that lets anyone add real-time, talking AI avatars to their app, website, or product.

The idea is simple: AI is becoming conversational, but most interfaces are still text boxes. We think the future of human-computer interaction involves seeing who you are talking to. Not a static image. Not a pre-rendered video. A real-time 3D character that listens, thinks, and responds naturally.

Whether you are building an AI tutor that helps students learn languages, a virtual companion that keeps someone company, or a receptionist that handles bookings around the clock, Avatarium makes it possible with minimal effort.

Why We Built This

If you have ever tried to add an interactive avatar to your product, you know the pain. You need 3D rendering, speech recognition, text-to-speech, lip sync, an AI brain, and somehow all of that needs to work together in real time with low latency.

Most teams give up. The ones that don't spend months building infrastructure that is not their core product.

Avatarium handles all of that. You get a single embeddable widget that does everything: real-time 3D rendering, speech-to-text, AI responses, text-to-speech with lip sync, and natural idle animations. Under 500ms response time.

What People Are Building

We designed Avatarium to be flexible enough for any conversational AI use case. Here are some of the most exciting ones:

🎓 AI Tutors and Language Coaches

Education is where avatars shine brightest. An AI tutor that students can see and speak to naturally creates a learning experience that feels personal and engaging. Language learners can practise conversation with a patient, always-available partner that speaks 100+ languages and corrects mistakes in real time. The visual presence of an avatar turns passive learning into active dialogue.

💬 Companions and Entertainment

AI companions are one of the fastest-growing categories in consumer AI. People want to talk to characters, not type to them. Avatarium lets you create companions with distinct personalities, voices, and appearances. The avatar laughs, nods, thinks, and responds with facial expressions that make the conversation feel alive. For gaming, interactive stories, or simply someone to chat with, avatars add a dimension that text never can.

🏨 Virtual Receptionists and Booking Agents

Hotels, clinics, restaurants, and service businesses need someone at the front desk 24/7. An AI avatar receptionist greets visitors on your website, answers questions about services and availability, takes bookings, and never calls in sick. It speaks the visitor's language automatically, handles multiple conversations at once, and hands off to a human when things get complex. Always on, always polite, always consistent.

How It Works

The architecture is straightforward:

Pick an avatar from our library or create a custom one using Ready Player Me
Connect a brain using your own API key (OpenAI, Anthropic, Google) or our managed models
Define behaviour with a system prompt, just like you would with any LLM
Deploy with one line of code

That last part is not marketing speak. Here is the actual embed code:

<script src="https://avatarium.ai/widget.js"
  data-avatar-id="YOUR_AVATAR_ID"
  data-api-key="YOUR_API_KEY">
</script>

That is it. Your avatar loads, renders in 3D, and is ready for voice conversation.

Bring Your Own Key

We believe you should control your AI costs. Every Avatarium plan supports BYOK (Bring Your Own Key). Plug in your existing Anthropic, OpenAI, or Google API key and pay your provider directly. We never mark up LLM costs.

If you do not want to manage API keys, we also offer managed brain models (Claude Haiku, Claude Sonnet) with simple per-minute pricing or included credits on higher plans.

Built for Developers

Avatarium is developer-first. We offer:

REST API for avatar management, session control, and analytics
SDKs for React, React Native, Flutter, Swift, Android, and vanilla JS
Webhooks for real-time event streaming
Dashboard for avatar creation, analytics, and billing

Voice Quality Tiers

Not every use case needs ultra-realistic speech. We offer three voice quality tiers:

Basic (Groq) for quick prototypes and internal tools
Standard (Deepgram) for production apps with natural-sounding speech
Premium (ElevenLabs) for the most realistic voice quality available

Pricing That Makes Sense

Every plan includes voice minutes, and you only pay for time your avatar is actively speaking. Idle time is always free.

Free: 30 minutes per month, forever. No credit card required.
Starter: $30/mo for 500 minutes
Studio: $92/mo for 750 minutes (most popular)
Pro: $100/mo for 1,500 minutes
Enterprise: Custom pricing for unlimited usage

We are also running a launch special where annual billing stacks with a 25% yearly discount for up to 50% total savings.

Meet Hiora

To show what is possible with Avatarium, we built Hiora: a free desktop companion app that brings your avatar to life on your screen. It is a lightweight app that sits on your desktop, always ready for a voice conversation. Think of it as your AI companion with a face. You can download Hiora for free.

What Comes Next

On our roadmap:

Custom avatar creation (upload your own 3D models)
Emotion detection and adaptive responses
Multi-avatar scenes for group interactions
Booking and calendar integrations for receptionist use cases
Mobile SDKs for iOS and Android

We are building Avatarium to be the infrastructure layer for every AI avatar interaction on the internet. Whether you are creating a tutor, a companion, a receptionist, or something we have not imagined yet, we would love to help.
