XHS Cover Generator

Generate Xiaohongshu (小红书) cover images with Chinese text overlays. Use when asked to create social media cover images, Xiaohongshu post images, or RED post covers. Supports split-screen comparisons, gradient backgrounds, and card layouts. Combines Pollinations.ai for AI base images with PIL for precise Chinese typography. Triggers on phrases like "小红书封面", "生成封面图", "make a cover image", "xhs cover", "xiaohongshu image".

Generate publication-ready Xiaohongshu (小红书) cover images (1080×1440, 3:4 ratio) with Chinese text overlays.

How It Works

1. Base image: Either AI-generated via Pollinations.ai (--base-prompt) or solid color background
2. Text overlay: Chinese text rendered with Noto Sans CJK font via PIL (auto-downloaded on first run)
3. Output: JPEG at 95% quality, ready to post

Styles

Style	Use Case	Example
split	A vs B comparisons	PUA式AI vs 暖心AI
gradient	Single-topic posts	AI工具测评
card	Clean/minimal posts	效率技巧分享

Usage

Run the generate script:

bash

python3 scripts/generate.py \
  --title "主标题文字" \
  --subtitle "副标题" \
  --style split \
  --left-label "左侧标签" \
  --right-label "右侧标签" \
  --base-prompt "english prompt for AI base image" \
  --output cover.jpg

Parameters

• --title (required): Main title text (Chinese OK)
• --subtitle: Secondary text line
• --tagline: Bottom tagline (split style only)
• --style: split | gradient | card (default: gradient)
• --left-label / --right-label: Labels for split style
• --left-color / --right-color: R,G,B colors (default: red/green)
• --base-prompt: English prompt for Pollinations.ai base image; if omitted, uses solid color
• --width / --height: Dimensions (default: 1080×1440)
• --output: Output path (default: cover.jpg)

Examples

Split comparison cover:

bash

python3 scripts/generate.py \
  --title "同一个问题，两种AI的回答" \
  --subtitle "差距有多大?" \
  --tagline "一招设置反PUA人设" \
  --style split \
  --left-label "PUA式AI" --right-label "暖心AI" \
  --base-prompt "cute flat illustration, split screen, left pink sad robot, right green happy robot, kawaii pastel" \
  --output pua-vs-warm.jpg

Gradient tool review:

bash

python3 scripts/generate.py \
  --title "2026最强AI编程助手" \
  --subtitle "Cursor vs Copilot vs Windsurf" \
  --style gradient \
  --base-prompt "futuristic code editor interface, purple blue gradient, clean minimal" \
  --output coding-tools.jpg

Card style tip:

bash

python3 scripts/generate.py \
  --title "用AI写周报只需30秒" \
  --subtitle "打工人效率神器" \
  --style card \
  --left-color "70,130,255" \
  --output weekly-report.jpg

Requirements

• Python 3 with Pillow (PIL)
• curl for font download and Pollinations.ai
• Internet access (first run downloads ~17MB CJK font, cached in /tmp)

Typical Workflow (for agents)

1. Determine the post topic and style
2. Craft an English prompt for the base image (descriptive, aesthetic keywords)
3. Run generate.py with Chinese title/subtitle
4. Send the resulting image to the user
