# ComfyUI 提示词小助手

> Updated: September 5, 2025

## 1. About ComfyUI Prompt Assistant

The Prompt Assistant is a very popular extension in ComfyUI. With the help of large model APIs provided by cloud service platforms such as SiliconFlow, it enables seamless prompt translation, expansion & refinement, and reverse-prompting from images directly within ComfyUI. It’s an essential tool for learning and using ComfyUI.

### Core Features

**Prompt Translation**: Instantly translate prompts between Chinese and English without manually setting source and target languages.

**Prompt Expansion & Refinement**: Define different rules based on the characteristics of image-generation or video-generation models, and expand & refine prompts with one click.

**Image-to-Prompt Conversion**: Use vision model APIs to convert image content into prompts with one click.

**Tag Presets**: Save commonly used prompt tags and trigger words as presets for quick insertion.
