Like the title says, I don’t code, and before this I had never made a GitHub repo or a custom ComfyUI node. But I kept hearing how impressive ChatGPT 5.4 was, and since I had access to it, I decided to test it.

I actually brainstormed 3 or 4 different node ideas before finally settling on a gallery node. The one I ended up making lets me view all generated images from a batch at once, save them, and expand individual images for a closer look. I created it mainly to help me test LoRAs.

It’s entirely possible a node like this already exists. The point of this post isn’t really “look at my custom node,” though. It’s more that I wanted to share the process I used with ChatGPT and how surprisingly easy it was.

**What worked for me was being specific:**

**Instead of saying:**

**“Make me a cool ComfyUI node”**

**I gave it something much more specific:**

**“I want a ComfyUI node that receives images, saves them to a chosen folder, shows them in a scrollable thumbnail gallery, supports a max image count, has a clear button, has a thumbnail size slider, and lets me click one image to open it in a larger viewer mode.”**

**- explain exactly what the node should do**

**- define the feature set for version 1**

**- explain the real-world use case**

**- test every version**

**- paste the exact errors**

**- show screenshots when the UI is wrong**

**- keep refining from there**

**Example prompt to create your own node:**

**"I want to build a custom ComfyUI node but I do not know how to code.**

**Help me create a first version with a limited feature set.**

**Node idea:**

**\[describe the exact purpose\]**

**Required features for v0.1:**

**- \[feature\]**

**- \[feature\]**

**- \[feature\]**

**Do not include yet:**

**- \[feature\]**

**- \[feature\]**

**Real-world use case:**

**\[describe how you would actually use it\]**

**I want this built in the current ComfyUI custom node structure with the files I need for a GitHub-ready project.**

**After that, help me debug it step by step based on any errors I get."**



Once you come up with the concept for your node, the smaller details start to come naturally. There are definitely more features I could add to this one, but for version 1 I wanted to keep it basic because I honestly didn’t know if it would work at all.

Did it work perfectly on the first try? Not quite.

ChatGPT gave me a downloadable zip containing the custom node folder. When I started up ComfyUI, it recognized the node and the node appeared, but it wasn’t showing the images correctly. I copied the terminal error, pasted it into ChatGPT, and it gave me a revised file. That one worked. It really was that straightforward.

From there, we did about four more revisions for fine-tuning, mainly around how the image viewer behaved and how the gallery should expand images. ChatGPT handled the code changes, and I handled the testing, screenshots, and feedback.

Once the node was working, I also had it walk me through the process of creating a GitHub repo for it. I mostly did that to learn the process, since there’s obviously no rule that says you have to share what you make. 



I was genuinely surprised by how easy the whole process was. If you’ve had an idea for a custom node and kept putting it off because you don’t know how to code, I’d honestly encourage you to try it.

I used the latest paid version of ChatGPT for this, but I imagine Claude Code or Gemini could probably help with this kind of project too. I was mainly curious whether ChatGPT had actually improved, and in my experience, it definitely has.

If you want to try the node because it looks useful, I’ll link the repo below. Just keep in mind that I’m not a programmer, so I probably won’t be much help with support if something breaks in a weird setup.

Workflow and examples are on GitHub.

I’m not a programmer, but I just built my own custom node and you can too.
