Generate Unreal Engine
Blueprints with AI.
Describe what you need in plain English and get a fully wired Blueprint: real nodes, correct pin types, execution flow, and variable setup. GraphDeck has no built-in AI and no subscription - bring the AI you already use (Claude, ChatGPT, Gemini, or your own key) and GraphDeck turns its output into a graph you can trust. Review it on a proper node canvas, then send it to Unreal Engine with a paste or a single click.
Watch a Blueprint build itself
Generating blueprint...
Cancel
An engine-validated 15-node graph, generated, wired, and deployed - exactly as in the app.
From description to working Blueprint
"Sprint with stamina that drains and recharges." "A door that opens when the player overlaps a trigger." Type it, or pick from built-in prompt patterns.
Whichever AI you've connected does the thinking, and GraphDeck turns its answer into a complete Blueprint graph: events, functions, variables, components, and every wire between them, auto-laid-out on the canvas.
Every node is checked against a real Unreal Engine node library: pin types, connections, missing links. Problems are flagged before they ever reach your project.
Export copies native Unreal clipboard data you paste straight into the Blueprint editor. Or skip the clipboard: the free Connector plugin deploys the asset into your project, compiled, in one click.
Why this beats asking a chatbot
You can ask any AI chat to "write a Blueprint" and get back a screenshot description or a wall of pseudocode you have to rebuild by hand, node by node. GraphDeck closes that gap.
Real nodes, real wires
Generation targets an actual Unreal Engine node library, so the output is a graph you can read, edit, and paste - not instructions for building one yourself.
Validation before it ships
Generated graphs run through GraphDeck's validation pipeline. Wrong pin types, dangling connections, and made-up nodes get caught on the canvas, not in your project.
Review before you commit
The graph lands on a full node editor first. Read it through, rearrange it, tweak values, delete what you don't want. Nothing touches Unreal until you say so.
Learn from every graph
Ask the AI to explain any graph and it teaches it like a lesson at a whiteboard, drawing rings and arrows on the exact nodes as it walks you through the logic.
Materials and Widgets too
Blueprints
Event graphs, functions, Construction Scripts, variables, and components. Multi-graph tabs mirror how Blueprints are actually structured in Unreal.
Materials
Full Material graphs with expression nodes, Material Result wiring, domain, and blend mode. Generate a look from a description and iterate on it.
Widgets
UMG Widget Blueprints: the widget tree, bindings, and the event graph behind them, generated together so the UI and its logic match.
More coming
Animation Blueprints, Control Rig, and MetaSounds are on the roadmap, built on the same generate-validate-deploy pipeline.
Bring your own AI. Or none at all.
GraphDeck doesn't run its own AI service, and there's no subscription. Connect an assistant like Claude over the built-in MCP server, use the free copy-prompt workflow with whatever AI chat you already use, or plug in your own API key. Your graphs stay on your machine either way.
Common questions
Is there a free AI Blueprint generator for Unreal Engine?
Yes. GraphDeck Free supports AI Blueprint and Material generation with no API key required - it works with the AI you already use, via the free copy-prompt workflow or the built-in MCP server with an assistant like Claude. Pro adds saving, the library, and more, as a one-time purchase - no subscription.
Which Unreal Engine versions are supported?
The node library covers Unreal Engine 5.7 and is updated with each major release. Clipboard export pastes into the UE Blueprint and Material editors, and the free Connector plugin deploys directly into your project.
Does it generate real Blueprint nodes or pseudocode?
Real nodes. The output is a fully wired graph validated against a real Unreal Engine node library, exported as native Unreal clipboard data. Paste it into the Blueprint editor and it's just nodes.
Does the AI see my Unreal project?
No. GraphDeck is a standalone editor and the AI works on GraphDeck's canvas. You choose exactly what context leaves your machine, and nothing touches your project until you paste or deploy.
What if the AI gets something wrong?
Validation catches structural mistakes on the canvas, and you review every graph before it goes anywhere. In Unreal, deployed assets are standard Blueprints - open them, compile them, change them like anything built by hand.
