独立开发了一个「图片转 AI 绘画 Prompt」的小工具，欢迎体验 大家好，最近利用业余时间做了一个小工具站 Find Image Prompt （ https://findimageprompt.com ），主要是想解决自己平时刷到好图、 但写不出对应 prompt 的问题，顺手做出来给大家用。 目前有四个小工具： - 图生 Prompt （ Image to Prompt ）：上传一张参考图，生成保留构图、 光影、风格的详细 prompt - 文生 Prompt （ Text to Prompt ）：一句话想法扩写成结构化的 prompt - AI 图片描述（ Image Describer ）：拆解一张图的主体、氛围、构图 - AI 生图：直接拿 prompt 出图，方便对照迭代、反复微调 不需要注册，有免费额度可以直接试。生成的 prompt 是比较通用的 描述性语言，理论上换到 Midjourney / SD / 其他模型也能用。 刚上线不久，功能还比较简单，欢迎大家来体验，有 bug 或者想加的 功能欢迎在帖子里说，我会尽量回复。
