Scan the project and get a searchable website with every Blueprint, its variables, functions, events, components and pictures of its graphs, plus a list of what to fix, the Blueprints worth moving to C++ and a safe cleanup. Copy any Blueprint as text for your AI assistant. No account, nothing leaves your machine.
Interactive demo with the plugin's real report for its test project. Sort, try Copy for AI and Clean up, see the C++ migration page, then Export docs.

The real documentation site Blueprint Scribe exported from the demo project: 14 assets,14 graph images and the audit. Search with /, open a Blueprint, click a graph to zoom.
Also in the export: scribe.json, the C++ migration report, one Markdown file per asset, for example BP_Door.md, and the AI-ready text, for example BP_Door for AI.
One page per asset: Actor, Component, Object, Widget and Animation Blueprints, interfaces, function and macro libraries, structures and enums. Parents, components, variables with their flags, functions with inputs and outputs, events, RPCs, dispatchers, widget hierarchies and more, all linked to each other.
Event graphs, functions, macros, collapsed graphs, anim graphs and states, drawn with the Blueprint editor's own graph widgets. Zoom and pan on the site.
Sidebar with every folder, search over assets, functions, variables, events and dispatchers, light and dark theme. No server needed.
A website for the team, Markdown for GitHub wikis or Obsidian, the whole report as JSON for CI, and compact text with the graph logic for AI assistants.
One click copies a Blueprint, or the whole list, as text an assistant can read: members, graph logic and findings, with a token estimate.
Every Blueprint gets a complexity score and a C++ score with the reasons. The C++ migration page ranks what to port first and what to fix before an engine upgrade.
Removes unused private variables and functions, dead, disabled and disconnected nodes after a preview. Public members other assets may use are kept.
What each asset uses, hard and soft, and what uses it, including the levels it is placed in.
The share of Blueprints, functions, events, dispatchers and public variables with a description, per asset and for the project.
Findings that point at a node open the Blueprint right there. The audit also runs in Data Validation and on the build server.
Scan, export and render graph images from your own pipeline scripts and Editor Utility Widgets.
Thirteen rules. Each one can be turned off and the limits are set in Project Settings, shared with the team.
| Rule | What it finds | Severity |
|---|---|---|
Compile | Blueprints with compile errors or warnings | Error / Warning |
Graph.Large | Graphs with more than 100 nodes | Warning |
Blueprint.Large | Blueprints with more than 300 nodes | Warning |
Tick | Nodes that run every frame; a warning above 20 | Warning / Info |
References.Heavy | Assets that load more than 50 MB of other content, with the biggest culprits | Warning |
Cast.Blueprint | Casts that make one Blueprint load another | Info |
References.Circular | Blueprints that hard reference each other | Warning |
Variable.Unused | Variables no graph reads or writes | Warning (private) / Info |
Nodes.Dead | Nodes that never run | Warning |
Nodes.UnusedPure | Pure nodes whose output goes nowhere | Info |
Nodes.Disabled | Disabled nodes | Info |
Nodes.Deprecated | Deprecated functions and nodes, with the engine's message | Warning |
Docs.Missing | Assets, functions, events, macros, dispatchers and non-private variables without a description | Info |
Run the commandlet on your build server to publish fresh docs and fail the build on errors, or script the whole thing from Python.

No. There is no AI service and no account. Everything is read from your Blueprints in the editor and written to a folder on your machine. The AI-ready text and Copy for AI only prepare text; you decide whether to paste it into an assistant.
Compact text of the assets in the list or of one Blueprint: parents, members, the logic of every graph and the findings, with the number of characters and an estimate of the tokens. Paste it into your AI assistant to ask about a Blueprint or plan a C++ port.
It shows a preview first and removes only what you tick. Private members nothing uses, dead, disabled and disconnected nodes are ticked; public members are listed but not ticked when other assets use the Blueprint, and Instance Editable, Expose on Spawn and Expose to Cinematics variables are always kept. The whole cleanup is one Undo step, and the Blueprints are compiled but not saved until you save them.
Complexity, 0 to 100, counts nodes, branches, loops, casts, graphs and members. The C++ score looks at per-frame work, loops, math, size and how many assets depend on the Blueprint. Both are explained in the docs, with every point.
No. The HTML site works offline straight from the folder or a zip. You can also upload it anywhere as a static site, like the sample on this page.
From the Blueprints themselves: Class Settings > Description, the Description of functions, custom events and macros, and the Tooltip of variables. Fill them in and the coverage goes up.
Yes. The commandlet writes the pages and the JSON report and returns an exit code based on the findings. Graph images need the editor UI, so for images start the editor with a Python script instead.
Every export replaces the pages, images, markdown, ai and assets subfolders of the output folder, so use a folder that only holds the docs. Blueprint Scribe marks it with a .blueprint-scribe file.
Scanning loads every Blueprint once. Scan the folders you need instead of the whole project if you only need part of it.
