Blueprint AI

The AI copilot for Unreal Engine

You describe what you want; the AI builds it. Create fresh assets, edit existing ones, or ask about what’s already in the project. Blueprint AI translates each request into operations Unreal validates before they run. What lands in your Content Browser compiles cleanly, opens in the right editor, and runs in PIE.

Create BP_Pickup as an Actor in /Game/Pickups. Add a StaticMeshComponent as root and a SphereComponent for overlap. On BeginPlay, print “Pickup ready”. On the sphere’s OnComponentBeginOverlap, call a custom function Collect.

Highlights

Lives inside the editor

An AI chat panel and a full terminal (ANSI colors, scrollback, command history) share a tab next to your viewport. Ask, build, and check the engine log without switching windows.

Acts on your team's tools

Connect Discord and GitHub and your copilot closes the loop without leaving the editor — announce a build or ping whoever owns the bug in Discord, triage issues and read a PR’s diff or CI logs on GitHub. Credentials stay on your machine and are handed only to the agent that needs them, never printed. Two integrations live today, more on the way. See integrations →

Every core Unreal asset type, end-to-end

If it ships with the base engine, Blueprint AI can create, edit, and inspect it — Blueprint and animation graphs, materials, VFX, audio, meshes, UI, gameplay systems, cinematics, world building, and the rest. Many engine-plugin asset types are covered too, the moment their plugin is enabled. Every new node lands in a tidy row-and-column auto-layout, no spaghetti graphs after an AI edit.

Costs far less to run

Blueprint AI sends Claude only what each task needs, so chats stay light and your subscription goes much further. Measured: the same “create a Widget Blueprint” task cost ~1,500 tokens vs ~3,900–9,600 for Epic’s own UE 5.8 MCP plugin (~2.6–6.4× fewer, single-domain), and ~9–14× lighter than the largest published competitor benchmark.

Works with the editor closed

Drive Blueprint AI from your terminal or CI through Claude or any other CLI-capable AI. It launches Unreal in headless commandlet mode, performs the operation, and exits. The editor never has to open.

Pre-loaded with the Unreal API

Bundles a full per-domain API reference, workflow guides, and a knowledge base: GAS, replication / Iris, motion matching, Mover, Substrate materials, PCG, World Partition, Enhanced Input, and more. The AI reads the relevant guide before it builds, so what lands compiles cleanly and follows engine best practices on the first try.

Smart defaults, your conventions on top

Ships opinionated by default: naming, GAS patterns, multiplayer, performance. Drop a CLAUDE.md or AGENTS.md at the project root and your team’s conventions layer on top, no fork, no edits to the plugin.

Optimized for Claude, open to any AI

The bundled chat panel runs on Claude, which needs a paid Claude plan (Pro or higher) or an Anthropic API key. Sign in once with your existing Claude account and the panel reuses it. The skill and CLI are agent-agnostic: Cursor, GitHub Copilot, Windsurf, OpenAI Codex, or any other CLI-capable AI can already drive Blueprint AI from the terminal through the self-documenting cli.py schema, and first-class panel integration for them ships next.
