md2 v0.2: Markdown → 公众号 · 知乎 · 小红书 · X / Threads / Bluesky / LinkedIn · 长图 · 封面.

Install the VS Code extension

New

  • VS Code extension: live preview beside the editor with every md2 tab, scroll sync, copy and export commands that write into your workspace, WeChat draft publishing, and AI with keys in SecretStorage.
  • Threads beyond X: Threads, Bluesky, Mastodon and LinkedIn, each with its own counting rules and image limits. Unicode-bold headings.
  • 长图 (long image) export in the web app, CLI (md2 long), MCP (md2_long_image) and VS Code.
  • Mermaid diagrams render to self-contained SVG (computed styles baked in, no <style>, no foreignObject), so they survive pasting into WeChat.
  • AI copywriting (bring your own key): Claude through the official Anthropic SDK (default claude-opus-5-5, structured JSON output, server-side refusal fallback) or any OpenAI-compatible endpoint. Covers 小红书 titles/caption/tags, thread rewrites, 公众号 headlines/digest and cover copy. Also available as md2 ai … and the md2_ai MCP tool.
  • Fine-tuning: line height, paragraph and letter spacing, 首行缩进, justify, heading alignment and custom CSS (--indent, --justify, --css … in the CLI).
  • English UI with a one-click 中文 / EN toggle, plus an English sample article.
  • ⌘/Ctrl⇧C runs the current tab's main action.
  • New logo.

Improved

  • MathJax loads lazily, which halves the web app's initial download (1.15 MB → 0.55 MB gzipped).
  • The CLI renders diagrams through headless Chromium, and publish wechat no longer needs a browser when the article has a cover.
  • The MCP server closes idle browsers and shuts down cleanly.

Fixed

  • The X thread no longer repeats the intro paragraph after the hook post, and keeps display formulas.
  • Inline Zhihu formulas no longer render as display blocks in the preview.
  • Long-image header fonts are no longer lost to quote escaping.
