What is it?

MarkCard Studio is a desktop authoring tool for creators who write long-form Markdown and want to publish it as a series of social media cards. You write in Markdown, the app splits the content into pages using one of several pagination strategies, and you choose a theme, a platform canvas, and a background before exporting the full set.

The app supports Xiaohongshu (3:4), Douyin (9:16), Weibo (6:7), square (1:1), and custom dimensions. It ships with 16 built-in themes and renders KaTeX formulas, Mermaid diagrams, highlighted code, tables, callouts, and interactive ECharts charts. Documents, local images, and exported output stay on the user's computer.

The project is built with Vue 3, Vite, and Tauri 2 with a Rust backend, and is licensed under GPL-3.0. It is still in active development, so interfaces and document behavior may change before a stable release.
