About this extension
Send to X4 is the essential tool for Xteink X4 owners. It lets you format and transfer long-form articles, newsletters, and even Twitter threads directly to your e-ink reader as clean, beautiful EPUB files.

🚀 What's New in v1.1.1
  • CrossPoint Support: Now fully compatible with both Stock and CrossPoint custom firmware.
  • Twitter/X Threads: Automatically stitches Twitter threads into a single readable chapter.
  • Smart File Manager: Sort, view, and delete your files directly on the device.

How it works
  1. Open any article or Twitter thread
  2. Connect to your X4's WiFi hotspot
  3. Click the extension icon
  4. Hit "Send to X4" — done!

Key Features
  • Universal Support: Works on blogs, news sites, Substack, and now Twitter/X.
  • Firmware Agnostic: Works perfectly with Stock Xteink firmware and CrossPoint (custom IPs supported).
  • Offline-First: No accounts, no servers, no cloud sync—your data never leaves your local network.
  • Advanced Manager: Organize your X4 library by Date or Name directly from the popup.
  • Download Option: Save the generated EPUBs to your computer if you prefer.

Perfect for
  • E-ink enthusiasts who want distraction-free reading
