IAMX Documentation

Build real-time, voice-conversational AI digital humans — in Unreal Engine and on the web.

Introduction

IAMX turns any character — a MetaHuman or your own custom rig — into a living, thinking digital human. It hears you, holds eye contact, answers in real time with perfectly synced lips, remembers you across sessions, and can take actions in your world. Instead of scripted dialogue trees, you get an actual conversation: the character listens while you speak, thinks with the language model you chose, and speaks back in a natural voice with facial performance to match.

The workflow is deliberately simple. You design a character once in the web panel — its personality, voice, AI model, knowledge and scenarios — then drop the IAMX plugin into Unreal (or paste a one-line embed on the web) and start talking. There is no pipeline to wire together, no models to host, and no ML plumbing to maintain in your project.

Everything is configured live from the web. Change a character's personality, swap its voice, raise its knowledge cutoff, add a new scenario or grant a new action — and the running character applies it on its next session. No rebuilds, no redeploys, no reshipping your game.

How IAMX fits together

IAMX is three cooperating layers. You mostly work in the first one; the other two do the heavy lifting so your project stays lean.

The round trip, end to end

Here is what happens between a person speaking and the character answering — typically in a fraction of a second:

  ┌────────────┐   voice    ┌───────────┐   understand   ┌────────────┐
  │  Person    │ ─────────► │  Client   │ ─────────────► │   Cloud    │
  │  speaks    │            │ (mic in)  │                │  (thinks)  │
  └────────────┘            └───────────┘                └─────┬──────┘
                                                               │
       lips + voice + eye contact + facial performance         │
  ┌────────────┐            ┌───────────┐   stream back        │
  │  Person    │ ◄───────── │  Client   │ ◄────────────────────┘
  │  hears &   │            │ (renders) │
  │  sees      │            └───────────┘
  └────────────┘

Because the intelligence is delivered at runtime, the same character can appear inside an Unreal build, on a website, and on a kiosk — all reading from one configuration in the panel.

What you can build

IAMX is a general-purpose engine for interactive digital humans. A few of the things teams build with it:

• Game & world NPCs — characters that actually converse with players instead of cycling through canned lines, and that can react and take actions in the game world.
• 24/7 interactive kiosks & receptionists — always-on digital humans that greet visitors, answer questions, and recognise returning guests.
• Virtual assistants & brand characters — a face and voice for your product or company that can answer, guide, and perform tasks on request.
• AI live-stream hosts & podcast duos — autonomous presenters, or two characters that talk to each other and to the audience in real time.
• Museum / showroom / training guides — knowledgeable hosts that walk people through an exhibit, a product line, or a lesson at their own pace.

What each build shares

Choosing your AI model

You pick which language model powers each character in the panel. IAMX supports the leading providers, so you can trade off quality, speed, cost, and privacy per character.

Design once, apply everywhere

The single most important idea in IAMX is that configuration is live. You never bake a character's brain into a build. Instead:

1. Create the character in the panel — give it a name, personality, voice and model.
2. Add knowledge and scenarios — upload documents it should know, and design the conversation flows it should follow.
3. Grant it actions — define what it is allowed to do in your world.
4. Connect a client — drop the plugin into Unreal or embed it on the web, pointed at that character.
5. Iterate freely — edit anything in the panel; the character picks up changes on its next session automatically.

Ready to build? Begin with the Quickstart to get a talking character running in minutes, read How it works for a deeper tour of the panel–cloud–client architecture, and follow the Unreal plugin install guide to add IAMX to your project. From there, the Blueprint API reference covers wiring the character into your game logic.
