Function

Article Sync (29+ Platforms) 🆕

Ported from the adapter architecture of Wechatsync. One click to sync the current article to 29+ mainstream platforms, saved as a draft by default.

Features

Uses your own sessions: reads the cookies already in your browser, no extra authorization, no password
Calls the official web APIs: exactly the same endpoints the platforms' own editors use
Your data never leaves the browser: all requests go directly from your browser to the platform, no middle server
Draft first: articles are saved as drafts by default, never auto-published
Automatic image transfer: images in the article are re-uploaded to the target platform
Per-platform content adaptation: platforms differ in what HTML they accept (links kept or stripped, whitespace compacted, code block format...), so the content is preprocessed separately for each target
Self-hosted blogs: WordPress, Typecho, MetaWeblog

Usage

Open any article page (WeChat, Zhihu, Juejin, CSDN, Cnblogs, ...)
Open the sync panel from any of these entries:
- Click the extension icon → Sync Articles
- The floating panel on the article page → 文章同步 / Sync Articles
- The panel on WeChat article pages → 文章同步
Check the extracted article, select the target platforms (the panel shows the login status of each one), then click 开始同步 (Start sync)
The panel reports per-platform status, draft links and keeps a sync history

Note: "Editor assist" means the platform does not expose a public draft API (or the API requires browser-side signing / risk-control checks). The extension opens the platform's official editor and prefills the title and content, then you confirm to save the draft or publish.

Self-hosted blogs (WordPress / Typecho / MetaWeblog)

Fill in the site URL, username and password under "self-hosted accounts" in the sync panel (the password is stored only in your local browser). WordPress users should use an Application Password.
