ComfyUI Comic Creator

English | 日本語 | 中文

A manga page creation SPA (single-page application) that runs on top of ComfyUI. Pages are managed in units of "works" (page groups); you create pages from templates, place images, speech balloons, text, shapes, and 3D poses into panels, and export as JPEG/PNG/WebP/PDF/EPUB. A layer-based image editor, font manager, AI image generation (Nanobanana), and script management are all built in, aiming to cover the entire manga-making workflow from a single node.

Features

Page / Work management

• Work (page group) management — Pages are grouped into "works" that carry a width/height. Templates are automatically resized to the work's size when inserted
• Templates — Create panel-layout templates either by importing an SVG or with the wizard (draw lines to split the page into panels). Templates assigned to a template group are shown under a collapsible group header in the Layout tab's "Templates" asset panel, making it easier to find the one you want as your template count grows
• Export — Export as JPEG/PNG/WebP/PDF/EPUB, including bulk export of multiple pages with sequential filenames. The libraries (jsPDF/JSZip) are bundled, so every format also works offline
• Automatic output size via resolution — The "Resolution" selector (72–600dpi) calculates the output pixel size from the work size (mm); manual input is still available. PDF conversion uses the selected dpi, preserving the physical page size (A4, etc.)
• Export metadata — Embed title, author, subject, and keywords into every format (PDF = document properties / EPUB = Dublin Core / PNG = iTXt / JPEG & WebP = XMP). Resolution (dpi) is also always embedded (PNG = pHYs / JPEG = JFIF density / WebP = EXIF), so all three formats report the same dpi
• Bulk backup / restore — Save all works, pages, templates, and settings into a single zip and restore anytime (merge mode: same names are overwritten)

Layout tab

• Image placement — Drag and drop images into panels; resize (aspect ratio locked by default, hold Alt to resize freely) and rotate with handles
• Sub-panels — Drag to add a rectangular or circular sub-panel inside a panel as a nested image target (e.g. an inset cut). Move, resize, and rotate with handles; parts that extend outside the parent panel are automatically cropped, just like any other object. Border thickness can be set per sub-panel. A "Move sub-panel" checkbox in the layer panel toggles whether clicking inside selects the sub-panel itself instead of the objects inside it. The layer panel's duplicate/move buttons also work on the sub-panel itself, including moving/duplicating it to another panel or to the overlay (re-parenting)
• Speech balloons — Place oval, rounded-rectangle, thought, burst, and cloud (puffy/wavy) shaped balloons inside panels, with 8-point resize handles. The Embed Text button lets you auto-wrap and embed text into any of these shapes (vertical writing, text color, Google/System/Category font selection, and double-click to re-edit an already-embedded text). Custom SVG balloons from assets can also have their fill/border colors changed after placement
• Text — Vertical/horizontal writing, Google Fonts / system fonts, a style modal for fill, stroke, outline, and shadow. Fills support gradients, textures (with adjustable X/Y position), and no-fill in addition to solid colors (shared between the Layout and Image tabs)
• Shape drawing (Draw) — Draw rectangles, ellipses, lines, curves, polygons, vector curves, chains, ropes, and My Curve directly onto an SVG layer. Polygons: click to add vertices, click near the start point to close. Vector curves: click to add nodes connected by a smooth spline, click near the start point to close as a filled shape, or press Enter to commit as an open line. Fills (rectangles, ellipses, polygons, vector curves, etc.) support gradients, textures (with configurable X/Y offset that follows the shape when moved or resized), and no-fill in addition to solid colors. Converting a shape to PNG preserves these fills as well
• 3D pose — Place a VRM/GLB/GLTF model inside a panel, pose it, and bake it into the image. Supports a draggable LookAt target and spring bone (hair/skirt) physics (via comfyui-vrm-pose-editor)
• Groups and layer panel — Group objects, manage stacking order, toggle visibility, lock, and delete with the Delete / Backspace key
• Draft layer — A draft-only layer that sits in front of the overlay and covers the whole page (images only). Clicks only reach it while it's selected (edit mode); otherwise clicks pass straight through to the overlay/panels/objects below. Never included in output (JPEG/PNG/WebP/PDF/EPUB). The Image tab's "Draft" button creates a canvas at the same aspect ratio as the active work at 72dpi, and "Send to Layout" automatically inserts it into this layer at full page size
• I2I integration — Send either a selected image (I2I) or a PNG render of the current page (PI2I) to Workflow Studio's Generate UI and bring the result back. A default workflow to auto-load can be configured in the Settings tab (via ComfyUI-Workflow-Studio)
• PixiJS FX — Apply particle/filter effects to the selected image from the "Image" sub-tab (via comfyUI-particle-pixijs)
• Manga tool — "Halftone" (an "Convert image" mode that halftones the selected image, plus a "Create pattern" mode that generates a halftone dot pattern sized to the panel/overlay), "Manga effects" (generate and insert vignette, screentone noise, and speed lines — radial / uni flash / uni ring / linear — as transparent objects sized to the panel), and "Background Pattern" (generate stripes, dots, checks, Japanese traditional motifs — asanoha/ichimatsu/shippou/uroko — or a custom SVG as a transparent object sized to the panel; adjustable color, opacity, size, and rotation angle, with independent width/height for custom SVGs). All three modals let you switch the preview background between the selected image, a checkerboard, and white while adjusting

Image tab (layer-based Canvas 2D editor)

• Select / Text / Draw / Shape / Fill / Mask / Blur / Filter / BG Remove / Upscale tools
• Crop (in the Select tool) — Set the crop area by dragging a resizable overlay (8 handles) or entering X/Y/width/height numerically, then apply. Resizes the whole canvas and shifts each layer's content to match (undoable)
• Draft canvas creation — The "Draft" button (next to New) creates a new canvas with no size dialog, sized at the same aspect ratio as the active work at 72dpi (for rough sketches). "Send to Layout" inserts it into the Layout tab's draft layer at full page size
• Eyedropper for the Draw tool — Pick a color directly from the canvas via the button next to the color picker
• Same Layer mode for the Shape tool — Keep adding shapes to the same layer instead of creating a new one for every shape. Rectangle/ellipse fills support gradients and textures (with adjustable X/Y position) in addition to solid colors
• Fill tool — Solid color fill, or linear/radial gradient fill with a color ramp and direction pad
• Mask tool — Paint/Color/Alpha/Text/Vector/Shape sub-tools, also supporting SAM3 segmentation and ABR brushes (tool set implemented with reference to comfyui-mask-editor-one). When Workflow Studio is installed, an Inpaint button is added to the sub-tool bar for mask + prompt-based generative inpainting (via ComfyUI-Workflow-Studio)
• PixiJS FX — Apply particle/filter effects to the active layer from a toolbar button (via comfyUI-particle-pixijs)
• Layer panel — Add, duplicate, delete, reorder, adjust opacity, and 12 kinds of adjustment layers (brightness, contrast, saturation, etc.). Multi-select layers and click Merge to combine only the selected ones (merging mask layers together keeps the result as a mask layer). The 📁 Group button on the toolbar's second row folds multi-selected layers into a collapsible group folder (with bulk show/hide and ungroup, undoable)
• Project saving — Save the entire layer composition and resume editing at any time

Font manager

• Preview Google Fonts and system fonts, with category management
• Create and save "Styles" (fill, stroke, outline, shadow) and "Presets" (font + size + style), and apply them instantly from the Layout / Image tabs

Nanobanana (AI image generation)

• Generate images via the Gemini API (Positive/Negative prompts, model, and resolution)
• Generated images are automatically saved to ComfyUI's own output/cc_nanobanana folder

Script tab

• Manage the screenplay in a hierarchy of Title → Synopsis → Plot [Pages → Panel breakdown (scene, elements, dialogue/description, etc.)]
• Insert any plot cell's content into the Layout tab as text with one click

External integrations

• Workflow Studio — Embedded gallery view, bidirectional I2I (image ↔ workflow) transfer
• Eagle — Save generated/edited images to Eagle automatically or manually
• G'MIC — Filter editing integrated with the G'MIC Qt GUI

Other

• Multilingual UI (i18n) — Switch between Japanese, English, and Chinese in the Settings tab (the entire Help tab is also available in all three languages)
• Help tab — A searchable, comprehensive in-app reference covering every feature

Installation

Manual installation

Place this folder inside ComfyUI's custom_nodes/ directory:

ComfyUI/
└── custom_nodes/
    └── comfyui-comic-creator/
        ├── __init__.py
        ├── py/
        ├── templates/
        ├── static/
        ├── web/
        └── assets/

This node requires no additional Python packages (aiohttp / Pillow are already bundled with ComfyUI itself), so no requirements.txt is needed.

After restarting ComfyUI, a CC button appears in the top bar. Click it to open Comic Creator (/ccc) in a new tab.

ComfyUI Manager

You can install it via ComfyUI Manager's "Install via Git URL" using the following URL:

https://github.com/ketle-man/comfyui-comic-creator

Optional setup

To use Nanobanana (Gemini API)

Create a .env file directly under this folder and add your Gemini API key:

NANOBANANA_API_KEY=your-api-key

Restart ComfyUI after saving.

To use G'MIC

In the Settings tab's "G'MIC Settings", specify the full path to the G'MIC Qt executable (gmic_qt.exe). It takes effect immediately after saving — no ComfyUI restart required.

To use Eagle integration

In the Settings tab's "Eagle Settings", check/change the Eagle API URL (default: http://localhost:41595). The Eagle app must be running.

Optional dependencies

Installing the following custom nodes enables the corresponding features. Nothing else is affected if they are not installed.

Companion node	Feature enabled
comfyui-vrm-pose-editor	The Layout tab's 3D Pose sub-tab
ComfyUI-Workflow-Studio	I2I integration, Inpaint in the Image tab, and the embedded gallery in the workflow studio tab
comfyUI-particle-pixijs	PixiJS FX (particle/filter effects modal) in the Layout tab's "Image" sub-tab and the Image tab

Usage

1. Open Comic Creator via the CC button in the top bar
2. In the "Page" tab's "Work Management", enter a work name and size, then click "New" (this automatically switches to the Layout tab)
3. Choose a template from the "Template" asset panel on the left of the Layout tab and click "Insert as Page"
4. Place and edit images, speech balloons, and text in the panels, then click "Save"
5. Repeat page navigation (◀▶) and template insertion to create multiple pages
6. In the "Page" tab's "Export", specify the format and range, then save

See the in-app Help tab (available in Japanese, English, and Chinese, with search) for full documentation.
