Installation

Option A — Manual (zip)

1. Download the repository as a zip file.
2. Extract the folder into <ComfyUI root>/custom_nodes/.
3. The resulting path should look like custom_nodes/ComfyUI-QualityOfLifeSuit_Omar92/.
4. Restart ComfyUI (a browser reload is not sufficient).

Option B — Git clone

cd <ComfyUI root>/custom_nodes
git clone https://github.com/omar92/ComfyUI-QualityOfLifeSuit_Omar92.git

Then restart ComfyUI.

After installation you will find all nodes grouped under O/… in the node search / right-click menu.

Tip: See how directory should look like.png at the repository root for the expected folder structure.

---

Configuration

On the first run ComfyUI will automatically create a config.json file inside the extension folder:

{
  "autoUpdate": true,
  "branch": "main",
  "openAI_API_Key": "sk-#################################"
}

| Key | Default | Description | |-----|---------|-------------| | autoUpdate | true | Pull the latest changes from GitHub every time ComfyUI starts. Set to false to disable. | | branch | "main" | Git branch to pull updates from. Use "dev" for the latest development changes. | | openAI_API_Key | placeholder | Your OpenAI API key. Required for all ChatGPT and DALL-E nodes. Get yours at platform.openai.com/api-keys. |

Security note: The API key is stored in config.json and is never embedded in generated images.

Simple ChatGPT Workflow

1. Add a ChatGPT Simple _O node.
2. Type your subject in the prompt field (e.g. "a futuristic cityscape at night").
3. Choose tags behaviour to get Stable Diffusion prompt tags, or description for a natural language description.
4. Connect the output STRING to your KSampler positive conditioning.

Advanced ChatGPT Workflow

1. Add load_openAI _O and enter your API key (or rely on config.json).
2. Create a Chat_Message _O with role = system to set the AI's behaviour.
3. Create another Chat_Message _O with role = user for your actual prompt.
4. Use combine_chat_messages _O to merge both messages.
5. Feed the result into Chat completion _O to get the AI's reply as a STRING.

---

Fonts

The fonts/ folder ships with several built-in fonts:

| File | Font | |------|------| | Alkatra.ttf | Alkatra | | CALIBRI.TTF | Calibri | | COMIC.TTF | Comic Sans | | COMICI.TTF | Comic Sans Italic | | COMICZ.TTF | Comic Sans Bold |

To add a custom font, copy any .ttf, .otf, or .ttc file into the fonts/ directory and restart ComfyUI. The font will appear automatically in the dropdown of the Text2Image _O node.

---

Auto-Update

The extension automatically checks for updates every time ComfyUI starts (when autoUpdate is true in config.json). It uses pygit2 to pull the latest commits from the configured branch.

To disable auto-update, open config.json and set:

"autoUpdate": false

To switch to the development branch for the latest (potentially unstable) features:

"branch": "dev"
