# MultiString Prompt Nodes for ComfyUI
|
|
|
|
This is a simple but powerful set of custom nodes for ComfyUI, designed to help you manage and sequence multiple prompts from a single, clean interface.
|
|
|
|
This pack contains two nodes:
|
|
|
|
---
|
|
1. **`MultiString Prompts`**: A utility node for managing and batching multiple *string* prompts. Ideal for feeding into loops or other nodes that process text.

|
|
|

---
|
|
|
|
2. **`MultiString Prompts Encode`**: An all-in-one encoder that takes your prompts and a CLIP model and directly outputs *conditioning* blocks, ready for a KSampler.

|
|
## How to Install
|
|
|
|
1. Navigate to your ComfyUI installation directory.
|
|
2. Go into the `ComfyUI/custom_nodes/` folder.
|
|
3. Create a new folder inside `custom_nodes` (e.g., `MultiStringNodes`).
|
|
4. Place all three files (`multi_prompt_node.py`, `multi_prompt_encode_node.py`, and `__init__.py`) inside that new folder.
|
|
5. **Restart your ComfyUI server.**
|
|
|
|
The nodes will be available by right-clicking the canvas and selecting **Add Node > MultiString Prompts**.

|
## 1. MultiString Prompts
|
|
|
|
This is the original string-management node. It's perfect for workflows like sequential video generation where you need to feed a series of different text prompts into your model.
|
|
|
|
### What It Does
|
|
|
|
* **5 Prompt Slots:** Provides five large, multiline text boxes for your main prompts.
|
|
* **Prefix & Suffix:** Includes two compact, single-line text boxes to add a `prefix` (like style or quality keywords) and a `suffix` to all of your prompts.
|
|
* **Enable/Disable Toggles:** You can instantly turn the `prefix` or `suffix` on or off using "true/false" dropdowns, allowing you to test prompts without deleting your keywords.
|
|
* **Smart Empty Handling:** If you leave a prompt box empty, the node outputs a completely empty string (it won't just output `prefix,suffix`).
|
|
* **List Output:** In addition to 5 individual string outputs, it provides a single `prompt_list` output. This is perfect for feeding all 5 prompts into a "Loop" or "Batch" node for a more compact workflow.
|
|
|
|
### Inputs & Outputs
|
|
|
|
* **Inputs**
|
|
* `enable_prefix` (toggle): Set to `true` to use the prefix, `false` to ignore it.
|
|
* `enable_suffix` (toggle): Set to `true` to use the suffix, `false` to ignore it.
|
|
* `prefix` (string): A single-line string added to the *beginning* of each prompt.
|
|
* `suffix` (string): A single-line string added to the *end* of each prompt.
|
|
* `multi_prompt_1` - `multi_prompt_5` (string): Five multiline text boxes for your individual prompts.
|
|
* **Outputs**
|
|
* `prompt_1` - `prompt_5` (string): The final, processed string for each corresponding prompt (e.g., `prefix,multi_prompt_1,suffix`).
|
|
* `prompt_list` (LIST): A single ComfyUI list that contains all 5 processed strings.
|
|

|
## 2. MultiString Prompts Encode
|
|
|
|
This is a powerful encoder node that handles both prompt processing and CLIP encoding in one step. It allows you to manage 5 separate positive prompts and one shared negative prompt.
|
|
|
|
### What It Does
|
|
|
|
* **Direct-to-Conditioning:** Takes your `CLIP` model as a direct input.
|
|
* **5 Positive, 1 Negative:** Provides five multiline text boxes for *positive* prompts and one multiline text box for a *negative* prompt.
|
|
* **Prefix & Suffix:** Uses the same powerful prefix/suffix system with toggles, which will be applied to all 6 prompt boxes.
|
|
* **Individual Outputs:** Outputs 6 separate `CONDITIONING` blocks (5 positive, 1 negative).
|
|
* **Workflow Power:** This is ideal for advanced workflows like regional prompting (where you need separate conditioning for different areas) or for creating prompt sequences where each positive prompt is encoded individually against a single, shared negative prompt.
|
|
|
|
### Inputs & Outputs
|
|
|
|
* **Inputs**
|
|
* `clip` (CLIP): The CLIP model to use for encoding.
|
|
* `enable_prefix` (toggle): Set to `true` to use the prefix.
|
|
* `enable_suffix` (toggle): Set to `true` to use the suffix.
|
|
* `prefix` (string): A string added to the *beginning* of all 6 prompts.
|
|
* `suffix` (string): A string added to the *end* of all 6 prompts.
|
|
* `positive_prompt_1` - `positive_prompt_5` (string): Five multiline text boxes for your positive prompts.
|
|
* `negative_prompt` (string): A single multiline text box for your negative prompt.
|
|
* **Outputs**
|
|
* `positive_1` - `positive_5` (CONDITIONING): Five separate positive conditioning blocks, one for each input prompt.
|
|
* `negative` (CONDITIONING): A single negative conditioning block.
