[GUI Plugin] reMarkable Sync: Send books to reMarkable via the desktop app

[mremond]

reMarkable Sync is a Calibre plugin that sends books from your library to your reMarkable tablet via the reMarkable desktop app, converts EPUBs to reMarkable-tuned PDFs, and can sync reading positions back to Calibre.

A free reMarkable Connect account is enough — no paid subscription required.

Highlights

• Send to reMarkable — selected books land in the desktop app's local store and sync to your tablet on next app launch.
• Export as PDF… — save the same reMarkable-tuned PDF anywhere on disk, no device required (handy for previewing or as a fallback upload path).
• EPUB → PDF conversion tuned per device (reMarkable 2, Paper Pro, Paper Pro Move): configurable font family, size, line height, per-edge margins, and page footer.
• Full-bleed cover inserted as the first page (top-aligned, padded with the cover's dominant edge color).
• Reading position sync — pull progress, current page, and last-read timestamp back into Calibre custom columns.
• Smart document naming: Series-Number Title - Author.

Requirements

• Calibre 5.0+ (tested on Calibre 9.7).
• The reMarkable desktop app installed and signed in (free Connect account is fine).
• After sending books, quit and restart the desktop app so it picks up the new documents and uploads them to your tablet.

Install

1. Download remarkable_sync-1.0.0.zip (attached to this post, or from the
   GitHub release).
2. In Calibre: Preferences → Plugins → Load plugin from file, pick the zip.
3. Restart Calibre. The plugin appears as reMarkable Sync in the toolbar and under Tools.
4. Open Tools → reMarkable Sync → Settings… to set your default folder, device type, conversion options, and (optionally) custom columns for reading-position sync.

Notes

• Developed and tested on macOS. Windows and Linux code paths exist but are currently untested — feedback very welcome.
