When users copy-paste content from Xiumi to WeChat Official Account editor, complex formatting (especially SVG elements) is lost. This extension solves that by programmatically injecting the HTML content into the WeChat editor, similar to Xiumi's native sync feature but without requiring WeChat Official Account OAuth authorization.

1. User designs article content on Xiumi (xiumi.us) website with rich formatting/SVG. 2. User opens WeChat Official Account article editor (mp.weixin.qq.com/cgi-bin/appmsg) in another tab. 3. User triggers send action from Xiumi. 4. Extension's crossoverSource.js on Xiumi page sends content via chrome.runtime messaging to serviceWorker. 5. ServiceWorker queries open WeChat editor tabs via crossoverSink.js. 6. ServiceWorker injects the content into the WeChat editor using MP Editor JSAPI or direct DOM manipulation, preserving all formatting.

Target users: WeChat Official Account content creators who use Xiumi (秀米) for article design / Chinese social media marketers and editors

Extension code is minified making exact logic tracing harder, but key flows are clear
Cannot verify whether Xiumi's website itself gates the 'send to WeChat' button behind its own login/payment
The extension only checks for version updates against xiumi.us API - no other API calls or external data collection observed

Monetization

No paid features detected

No payment, subscription, premium, upgrade, license, VIP, or billing keywords found anywhere in the extension source code. No payment platform integrations (Stripe, PayPal, etc.). The popup UI only shows version info and links to Xiumi. The extension's transfer functionality (Xiumi to WeChat editor) is fully implemented without any feature gating. While the Xiumi platform itself may have paid tiers, the extension does not gate any of its own functionality behind payment.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension itself has no login UI or auth mechanism. However, the core workflow requires the user to be logged into two external services: (1) Xiumi (xiumi.us) to create/edit content, and (2) WeChat Official Account backend (mp.weixin.qq.com/cgi-bin/appmsg) to receive the transferred content. crossoverSink.js reads account nickname/thumb from the WeChat editor DOM (`.weui-desktop-account` selectors) to identify the logged-in account. Without being logged into both services, the extension's transfer functionality cannot work.
