CSDN Sync

CSDN Sync opens the current Obsidian note in the CSDN Markdown editor and fills the title, Markdown body, and local images.

It uses a local bridge:

• The Obsidian plugin reads the active Markdown note and starts a localhost task server.
• The companion Chrome extension uses your existing CSDN login session in Chrome.
• The extension opens the CSDN editor and inserts the note content. You still review and save or publish manually.

Requirements

• Obsidian desktop app.
• Google Chrome.
• A signed-in CSDN account in Chrome.
• The companion Chrome extension from this repository.

This plugin is desktop-only because it starts a local HTTP server and depends on a browser extension.

Image handling

Local Obsidian images are uploaded to CSDN image storage before the Markdown is inserted. Remote images are left as Markdown links.

Privacy and data

CSDN Sync does not collect analytics and does not send vault data to any service controlled by this project.

When you run the sync command:

• The active note title, Markdown body, and referenced local images are exposed on 127.0.0.1 for the companion Chrome extension.
• Task endpoints require the token shown in the plugin settings.
• The Chrome extension sends the note content and images to CSDN only when you explicitly run the command.
• The local server listens on 127.0.0.1 only.

Limits

• Only the active Markdown file is supported.
• The plugin does not publish articles automatically.
• The plugin does not edit existing CSDN articles.
• CSDN editor UI changes can break the fill flow.
