# Prompt concatenator

The Concatenate node merges text from different sources (user prompts, brand guidelines, AI text outputs) into one ordered prompt that feeds into downstream AI generation nodes. 

### When to use it

* **Standardizing prompt structure**: Ensure every generation follows the same format (e.g., subject first, then style, then technical specs).
* **Building complex prompts from multiple sources**: Pull together outputs from several AI Text nodes into one generation-ready prompt.
* **Combining user input with brand context**: Merge a creative brief with your brand guidelines into a single, structured prompt.
* **Batch workflows**: Process multiple prompt variations in loop mode.

### How it works

1. **Connect your text sources**: Link any nodes that output text (prompts, brand context, AI text) outputs.
2. **Set the order**: Arrange inputs in the sequence you want them to appear in the final prompt.
3. **Done!**
