rmSync

Your handwritten notes, on your Mac. No cloud required.

rmSync connects to your e-ink tablet over Wi-Fi, pulls your notebooks via SSH, and renders them in a native desktop app. No subscriptions, no cloud accounts, no friction — just your notes, locally.

---

Get Started

Prerequisites: Node.js 18+ and SSH enabled on your tablet.

git clone https://github.com/ciesko/rmSync.git
cd rmSync/src
npm install
npm start

On first launch:

1. Click Settings → enter your tablet's IP (10.11.99.1 by default) and SSH password
2. Click Sync
3. Your notebooks appear. That's it.

💡 Where's the SSH password? On your tablet: Settings → Help → Copyrights and licenses — scroll to the bottom.

After the first sync, rmSync auto-syncs every hour in the background. If your tablet isn't reachable, it quietly retries later.

What You Get

📄 PDF upload — drag PDFs into the sidebar to send them to your tablet.

🔍 Trackpad zoom & pan — pinch-to-zoom and two-finger scroll, native macOS feel.

🎬 Ink reveal — strokes animate in writing order when you open a page. See how your notes were written.

🌈 Temporal gradient — press T to color strokes by writing order. Instantly spot what was added last.

📐 Grid view — press G to see every page at a glance. Click any thumbnail to jump there.

🧘 Focus mode — press F or double-click to dissolve all UI chrome and just see your writing.

How It Works

  Your tablet                         Your Mac
 ┌───────────┐    SSH / SFTP    ┌────────────────┐

                                └────────────────┘

Everything stays on your local network. Notes are cached in ~/.rmsync/ so you can browse them offline.
