Hi everyone,

I wanted to share a ComfyUI custom node I recently developed for Ideogram 4. This node helps you visually design layouts and arrange prompts more intuitively right inside ComfyUI.

I took a lot of inspiration from KJ Nodes and LTX Director while making this.

Key Features

Ideogram 4 JSON Prompt Builder: Generates structured JSON prompts optimized for Ideogram 4.

Visual Bounding Box Editor: Draw, resize, and modify layout zones directly on the canvas.

Element Organization: Easily organize elements like text, logos, signatures, and titles by specific areas.

External JSON Loading: Import prompt drafts from other nodes, like the Local LLM Loader.

Safe Mode: Asks for confirmation before replacing an existing board with a new JSON, preventing accidental overwrites.

Error Resilience: Displays a warning instead of crashing your workflow if an invalid JSON is entered.

Translate On/Off Helper: Assists with converting prompts into English.

Text Preservation: Keeps the actual text content inside the TEXT field exactly as it is, even during translation.

How to Use

Install Deno Custom nodes via ComfyUI.

Set your desired canvas aspect ratio and resolution.

Arrange your visual zones by placing bounding boxes on the canvas.

Input the role, description, and exact text content for each box.

Use the generated Ideogram 4 prompt and bbox data in your workflow.

(Optional) Connect it with a Local LLM Loader to automatically bring in prompt drafts.

I'm also sharing the workflow used in the demo video. If you're using it for the first time, just load this up, tweak the box positions and text, and you’ll get the hang of it pretty quickly.

The main focus of this node isn't about writing "longer prompts"—it’s about visually mapping out your image components and organizing the structured data for Ideogram 4.

Let me know if you have any feedback or ideas for improvement!
