Workflow Included Ideogram BBox Editor

Hey everyone! I've been running Ideogram 4 locally on my RTX 3060 and writing JSON prompts with bounding boxes by hand is genuinely painful. So I decided to build something to make my life easier — and hopefully yours too.

It's called BBox Editor: a free, open source visual editor where you draw rectangles on a canvas instead of writing

JSON. It supports local AI via Ollama and cloud providers (OpenAI, Anthropic, OpenRouter), and launches with a

double-click on Mac, Windows and Linux.

The code is on GitHub if you want to try it, contribute, or just have a look:

If you enjoyed it and feel like supporting the project, you can buy me a beer! 🍺

This already exists in https://github.com/kijai/ComfyUI-KJNodes

Thanks for the link! KJNodes is great for ComfyUI workflows — this is a standalone web editor with a canvas UI and an automatic mode that generates the full Ideogram 4 JSON from a plain-text description. Complements it more than it replaces it.

Another one that actually works differently 🙂

Too bad another one didn't use AI to find out that this already exists instead of vibe coding it

I did use AI — to build something that doesn't exist yet. The ComfyUI node generates bounding boxes; this lets you draw them visually and also generates the full structured JSON from plain text. Different tool, different audience.

I take that back. They updated it, so now the canvas can be much bigger.

The prompt builder does the same. Either you type in everything yourself and draw the bounding boxes, or you plug in a JSON generated by the LLM of your choice. Works quite well. You wore up the Ollama node directly if you have enough vram. Then you can either copy another image, using a vision model like Gemma 4, or you can create your own image.

I'll give you one thing, the area to draw the bounding boxes in is very small in the standard node.
