Type @ in the ⚡ Dynamic Tag Loader prompt editor to search for and insert tag .txt files. Inserted tags appear as chips and can be freely mixed with normal text. Click a chip and use Ctrl + ↑ / ↓ to adjust its strength with ComfyUI's native rules; Backspace, Delete, copy, and paste are supported for quick editing.

Installation

Navigate to your ComfyUI custom_nodes directory:

cd ComfyUI/custom_nodes/
git clone https://github.com/NineKey1028/ComfyUI_Dynamic_TagLoader.git

Restart ComfyUI.

⚡ Dynamic Tag Loader

Quickly read and sort organized .txt files from tag folders. Supports LoRA reading and can be connected to the 🔄 Dynamic Tag Iterator for random prompts and batch output.

More...

Global Prompt: Always appears on the first line of all output combinations.

+ Add Tag Group: Click to add a new folder to read; you can add unlimited groups as needed.

Tag Group:

Folder: The current folder being read. Click to open a menu and switch folders.

File: The file currently selected in the folder. Choosing ALL will combine all .txt files in this folder with files from other groups for full combinatorial output.

LoRA Support: Supports writing <lora:lora_name:weight> directly in .txt files or the Global Prompt. The node automatically extracts the syntax, loads model weights, and cleans the syntax from the final prompt.

Context Menu: Right-click any Tag Group to "Move Up/Down," "Move to Top/Bottom," "Insert New Group," or "Delete Group."

🔄 Dynamic Tag Iterator

Receives the combination list from the Dynamic Tag Loader and performs single iterations or batch outputs based on settings.

More...

Output Mode:

Iterate (One by One): Works with ComfyUI's queue mechanism. Outputs one combination per execution (switches index order based on Seed).

Batch (List): Outputs all combinations (or a filtered list) at once, suitable for nodes that support list processing.

Sample Limit: Sampling restriction. Set to 0 to use all combinations; if > 0, it randomly selects a specified number of items from the pool based on the current Seed.

Seed Control & Records:

The node determines the iteration index or random sampling order based on the Seed.

♻️ Reuse Last Seed: Automatically records the Seed from the last successful run. Click to quickly fill it back into the Seed input to reproduce specific combinations.

💾 Dynamic Tag Saver

Saves prompt text instantly as a .txt tag file and automatically integrates selected LoRA syntax. Helps users build personal tag libraries for future use with the Dynamic Tag Loader.

More...

Text Input: The main prompt input area. Extra spaces are trimmed automatically.

Folder & Filename:

Folder Name: Specify the save directory. If it doesn't exist, it will be created (within the tags folder in the node directory).

Filename: Specify the file name. If a duplicate exists, a suffix (e.g., _1, _2) is added to prevent overwriting.

LoRA Auto Merge:

+ Add LoRA: Opens a search menu to select installed LoRA files.

Strength: Adjust weights (supports -10.0 to 10.0).

Auto Integration: Upon saving, selected LoRAs are converted to <lora:name:weight> and appended to the text.

Advanced Menu: Right-click the LoRA block to reorder or delete entries.

🔍 Workflow Metadata Reader

Extracts complete Workflow JSON data from generated images (PNG). It retrieves content based on Node IDs to output prompts and images. Supports single image parsing or random selection from a directory.

More...

image_or_dir: Input a file path or a directory path.

Search By:

ID: Locates and extracts all widget values (Prompt, Seed, etc.) via Node ID.

Type: Filters and extracts text based on node type (e.g., CLIPTextEncode).

Selection Logic:

Directory Mode: Uses the Seed to randomly sample images from a folder.

Single Image Mode: Reads info from a specific file.

Note: Supports Drag & Drop or Ctrl+V to paste images (copies them to the input folder).

⚠️ Warning: For prompts to be read correctly, the workflow should use a node like Show Text and the prompt must be written to the metadata before image generation. If execution order issues occur, use the ⏳ Wait For node.

⏳ Wait For

Forces execution order in ComfyUI's non-linear environment. Ensures a "Target Node" finishes before the subsequent node begins.

More...

Data Input: The primary data to pass through (AnyType).

Wait For (Optional): Connect to the output of the node you want to finish first. Data is only released once this connection receives data.

Example Workflows: You can drag these into ComfyUI to load and read the example workflows.
