YouThumb Prompts — Thumbnail Prompt Generator

YouThumb提示词 — 缩略图提示词生成器

Generate 5 optimized, ready-to-paste prompts for YouThumb.ai thumbnails.

Follow the 4 steps in order. Do not skip ahead or generate prompts before collecting all info.

为YouThumb.ai的缩略图生成5个优化的、可直接复制粘贴的提示词。

请按顺序遵循以下4个步骤，在收集完所有信息前不要超前操作或生成提示词。

Step 1 — Person

步骤1 — Person

Ask the user:

Who will be on the thumbnail? Give me the name exactly as registered in YouThumb.ai.

Store the name. This is the subject referenced in every prompt.

If the user hasn't created a Person yet:

Go to YouThumb.ai → Persons → Create. Upload 3-5 clear face photos (different angles, good lighting). Name it exactly as you want to reference it.

询问用户：

缩略图上会出现哪个人物？ 请提供你在YouThumb.ai中注册的完全一致的名称。

存储该名称，这是所有提示词中都会引用的主体。

如果用户还未创建Person：

前往YouThumb.ai → Persons → 创建。上传3-5张清晰的面部照片（不同角度、光线良好），按照你想要引用的名称精确命名。

Step 2 — Assets

步骤2 — 素材

Ask the user:

What visual elements should appear on the thumbnail? List each with:

Name — what it is (logo, screenshot, icon...)

Description — what it looks like or represents

Examples:

"Claude Code logo — purple/orange terminal icon"

"Screenshot of my app — dark theme with charts"

Map each asset to

@image1

@image2

@image3

etc. (max 5, in order given).

Display the mapping back:

@image1 → Claude Code logo (purple/orange terminal icon)
@image2 → VS Code logo (blue code editor icon)

⚠️ Every asset MUST be referenced as
@imageN (description)
in the prompts. Without this, YouThumb will NOT include the image.

询问用户：

缩略图上需要出现哪些视觉元素？ 请按以下要求列出每一项：

名称 — 元素类型（logo、截图、图标等）

描述 — 元素的外观或代表的含义

示例：

"Claude Code logo — 紫色/橙色终端图标"

"我的应用截图 — 深色主题带图表"

将每个素材映射为

@image1

、

@image2

、

@image3

等（最多5个，按照用户提供的顺序排列）。

将映射关系反馈给用户：

@image1 → Claude Code logo (purple/orange terminal icon)
@image2 → VS Code logo (blue code editor icon)

⚠️ 所有素材在提示词中必须以
@imageN (描述)
的格式引用，否则YouThumb不会在生成结果中包含该图片。

Step 3 — Video Description

步骤3 — 视频描述

Ask the user:

Describe your video:

What's the topic?

What's the angle/hook? (comparison, tutorial, news, opinion, reveal...)

What emotion should the thumbnail convey?

Any style preference? (dark, colorful, minimal, dramatic...)

询问用户：

描述你的视频：

主题是什么？

切入点/钩子是什么？（对比、教程、新闻、观点、揭秘等）

缩略图需要传达什么情绪？

有没有风格偏好？（深色、多彩、极简、戏剧化等）

Step 4 — Generate 5 Prompts

步骤4 — 生成5个提示词

Using Steps 1-3, generate 5 distinct prompt variations, each 100-300 words.

基于步骤1-3收集的信息，生成5个不同的提示词变体，每个长度在100-300词之间。

Step 3 — Video: "Comparing React development with and without AI. Angle: productivity boost. Mood: impressive, tech-forward."

One of the 5 generated prompts:

Alex Dev on the left third of frame, medium shot from waist up, confident smirk with one eyebrow slightly raised, arms crossed. @image1 (React blue atom logo) floating at mid-right, softly glowing with a blue aura. @image2 (Claude Code purple terminal icon) hovering below and behind, emitting subtle orange light trails. Clean dark background with a deep navy-to-black gradient, single teal light source from upper left casting soft directional shadows. Subtle floating particles catching the light. Chrome-like reflective floor adding depth. Shallow depth of field with background elements slightly soft. No text.

Expression: confident | Background: dark navy + teal | Assets: @image1 mid-right glowing, @image2 behind lower

步骤1 — Person： "Alex Dev"
