Why this exists

I bought a reMarkable because I wanted a paper-like place to put my thoughts. What I didn't want was the trade-off I got handed to retrieve them.

Either pay a monthly subscription and let my most private notes live on someone else's servers, or make do with a web interface that gets painfully slow once your library grows, or open a terminal and SSH into the tablet like it's a server.

What I actually wanted was an iTunes for the reMarkable — feature-packed, private by design, and easy enough to use without thinking about it. That's what reHydrate is.

A library that belongs to you.

Search across every notebook. Organise them into folders. Open any document as a sharp PDF — pens, fineliners, markers, and highlighters all rendered crisply, ready to print or share.

Every sync keeps a snapshot. Decided you preferred last week's draft? Open the history view and restore it.

The reHydrate library window. A sidebar lists All Documents, Recently Synced, Pending Sync, Notebooks, PDFs, EPUBs, custom folders, an archive bin, and a device section. The main pane lists notebooks and PDFs with type, size, page count, and last-synced columns.

Think with your hand. Publish anywhere.

Most of us create on a glowing screen now — straight into a browser tab, with notifications buzzing in the corner and the next link a click away. The thought you almost had gets buried before you finish it.

Writing by hand is the opposite. Ink on a page. Nothing to switch to. No autocomplete second-guessing the sentence you started. It's a different — and quieter — way of thinking, and the ideas that come out of it tend to be the ones worth keeping.

reHydrate carries those ideas the rest of the way:

Sync your notebook. Right-click any page and let a local Ollama model turn your handwriting into Markdown. From the same window, publish a draft straight to your WordPress or Ghost site.

Ollama runs on your computer, not in a cloud somewhere. Pick the model that fits your hardware — a 4B model fits comfortably on 8 GB of RAM; bigger models do better on cursive and equations. Your pages never leave the network you're sitting on.

Idea → ink → transcript → draft. The whole creative loop, on your machine until you decide to ship it.

Built in the open.

reHydrate is free, open-source software, dual-licensed under MIT and Apache-2.0. The goal is simple: make a useful, stable app that other reMarkable owners actually want to use. The only way that happens is with people sending bug reports, feature ideas, and the occasional patch.

The whole source tree, issue tracker, and release notes live on GitHub. If something's broken, file a bug. If you'd like to see a feature, open an issue. If you want to send code, CONTRIBUTING.md walks you through dev setup, the commands CI runs, and how to open a pull request. Anything tagged good first issue is a fair place to start.

Security issues go through GitHub's private advisory form, not public issues. See SECURITY.md for the full disclosure policy.
