Zhongtu — Chinese Diagram Studio
A hosted SaaS that wraps the guizang material-illustration skill into a no-installation web app: a WeChat public-account editor or Xiaohongshu creator pastes text, a chart screenshot or a rough concept and gets back a labeled Chinese-language explanatory diagram ready to drop into their post or PPT.
Chinese content creators (公众号 editors, 小红书 knowledge creators, online educators) who explain ideas in long-form Chinese and need diagrams with real labels, not decoration
- Text-to-labeled-diagram with Chinese labels and source data preserved
- Chart beautifier: paste a screenshot or numbers, get a restyled, more readable chart
- Niche-concept reference lookup so brand logos, science apparatus and frameworks are drawn correctly
- Preset crops for 小红书 3:4, WeChat 公众号 header, and PPT 16:9
The original CLI skill just hit 207 GitHub stars proving real creator demand, but it requires Claude Code/Codex and shell access — a hosted Chinese-creator SaaS unlocks the much larger WeChat/Xiaohongshu creator market that doesn't live in a terminal.
Adjacent 归藏 PPT Skill hit 10K+ GitHub stars in 25 days (multiple Chinese tech blogs confirm), proving strong creator demand for AI-generated Chinese design output; the specific material-illustration repo exists but 207-star claim not directly verified; 公众号 AI editor market is crowded and active.GitHub - op7418/guizang-material-illustration: 归藏的材质插画 skill ↗一个 25 天破万 Star 的 PPT Skill，确实有点强 - 知乎 ↗2025年6大公众号编辑器深度横评 ↗
Existing 公众号 editors (壹伴, 秀米, 135, 96, 小墨, WeMark) focus on text typesetting and stock-style 配图, not labeled Chinese explanatory diagrams — the guizang skill's '带字解释图' angle has few direct SaaS competitors.2025年6大公众号编辑器深度横评 ↗WeMark | 完全免费的AI公众号编辑器 ↗
Chinese creators routinely pay for editor SaaS subscriptions and AI tool memberships, but willingness to pay specifically for a narrow diagram-generation tool is unverified — the ecosystem shows tiered pricing but this niche sits inside larger bundled editors.别盲买 Ai 会员了：2026 年主流订阅价格、能力差异和搭配方案 ↗2025年12月公众号ai排版工具攻略 ↗
Chinese long-form content creation on 公众号/小红书 and AI-assisted design are both durable multi-year trends; labeled diagrams remain a core need for explainer content.2025实测对比：6款公众号AI编辑器 ↗
Wrapping an existing open-source skill into a hosted SaaS is feasible but requires LLM/image-gen API integration, payment, WeChat-Xiaohongshu export pipelines, and ongoing inference cost management — non-trivial infrastructure work.新媒体运营用AI排版工具｜10分钟搞定公众号图文的全流程指南 ↗
