IAMX for Unreal Engine — now available on Fab

The IAMX plugin for Unreal Engine is live on Fab. You can now drop a real-time, talking AI character into any Unreal project — one that hears you, looks at you, answers in its own voice with synced lips, remembers you next time, and can actually do things in your world.

What the plugin gives you

Real-time conversation — speak or type, get an answer back in seconds
Accurate lip sync — mouth shapes generated from the actual audio, not canned animation
Emotions and facial expression — mood shifts with the conversation and shows on the face
Long-term memory — it remembers who it talked to, across sessions
Actions in your world — wire conversation to Blueprints so the character can move, trigger events or call your own systems
Knowledge base — upload your documents and the character answers from them
Vision — the character can see and talk about what it sees
Any character — MetaHuman out of the box, or your own rig via custom blend shape mapping
Your choice of model — OpenAI, Anthropic Claude, Google Gemini or Groq, switchable per character

Built for six engine versions

One plugin, six engine versions — UE 5.3 to 5.8

Prebuilt packages ship for Unreal Engine 5.3, 5.4, 5.5, 5.6, 5.7 and 5.8, so you can install it into the project you already have instead of upgrading around it.

Getting started takes about ten minutes

Install the plugin from Fab and enable it in your project
Create a character in the IAMX Studio at iamxlive.com — personality, voice, language
Paste your API key into the plugin, drop the IAMX component on your character, press Play

Everything heavy runs in the cloud, so your project stays light and the same character works in-engine, on the web, on a kiosk or over the phone.

Try it first

You can talk to a live digital human right now in your browser, no signup — iamxlive.com.
