20条AI悬疑推理与惊悚小说封面提示词
惊悚小说的封面上，主角不是图像，而是书名。翻开任何一份畅销榜单：一个大胆的图形创意，加上大片留给超大字号的空间。下面的提示词正是这样构建的：一个冷峻的主体、强烈的对比，以及保持沉默的上三分之一，好让你的书名来放声呐喊。
悬疑推理小说封面如何构图
- 只用一个图形创意，并放到最大。畅销惊悚小说只展示一件物品或一道剪影，从不画完整场景，情节留在书里。
- 把上三分之一留给书名。惊悚小说的惯例是超大字号；画面一旦侵入这块区域，就会让你丢掉一次成交。
- 冷色打底，只用一个警示色。钢蓝、石墨灰和雨灰色营造氛围；唯一的点缀色，比如钠灯橙或血红色的细绳，负责引导视线。
- 别用手枪。它是这一类型里最常见的图库照片；一只手套、一把钥匙或一扇亮灯的窗户，更具体、更令人不安，也更少被用到。
- 对比就是惊悚感。近乎纯黑加一束硬光，能经得住Amazon缩略图的考验；一团混在一起的中间调，看上去像文艺剧情，而不像悬疑推理。
痕迹
犯罪是通过它留下的东西来讲述的：柏油路上的一只手套、排水沟里的钥匙、潮水线边的一只鞋。单独一件被强光照亮的物体，在缩略图尺寸下一眼就能看清，并抛出浏览者无法忽视的那个问题：这里发生了什么？

图像模型仍然会把文字画成乱码，所以上面的每条提示词都禁止在画面中出现文字，并让上方三分之一保持干净。书名之后会以真正可编辑的文字排上去，使用所选类型的标题字体；想改一个词、翻译或调整大小，都不必重新生成画面。
用自己的书名试一试
常见问题
这些提示词为什么都写了“无文字”？
图像模型仍然会把文字画成乱码，而且直接嵌入画面的书名既无法编辑、翻译，也无法缩放。这里的每条提示词都禁止画面中出现文字；你的书名随后会作为真正的文字排上去，在工作室里会自动使用悬疑推理与惊悚类的展示字体。
这些提示词是为哪种AI工具写的？
长版本适用于任何图像模型：Midjourney、DALL·E、Stable Diffusion、Flux。短版本是为PrintReadyCovers的创意简述栏写的，它会替你补上该类型的美术指导和书名留白规则。
带AI封面的惊悚小说能在KDP上销售吗？
Amazon允许AI辅助生成的内容，并要求你在出版时声明使用了AI。通过付费商用API生成（本工作室就是这样做的），并在上传前核对KDP现行的内容准则。
如何让封面在缩略图尺寸下依然清晰可读？
一个主体、一个光源、两级明暗，然后测试一下：把封面缩小到约160像素高，看书名是否依然可读。本站的免费缩略图工具做的就是这件事。
