The IAMX plugin for Unreal Engine is now live on Fab. You can 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 — the character’s mood shifts with the conversation and shows on its face.
- Long-term memory — it remembers who it talked to and what was said, 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 through a camera or the scene and talk about what it sees.
- Any character — MetaHuman out of the box, or your own rig with custom blend shape mapping.
- Your choice of model — OpenAI, Anthropic Claude, Google Gemini or Groq, switchable per character.
Built for six engine versions
The listing ships prebuilt packages 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 — give it a personality, a voice and a language.
- Paste your API key into the plugin, drop the IAMX component on your character, and 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.
