Apps over your own Markdown files

Every Pure app works on the same material: plain Markdown files, in folders you own, synced by whatever you already use. Each app does one job: editing a file, writing, task boards, a personal wiki. The document is edited as formatted text while the file on disk stays plain Markdown. Delete an app and your files remain exactly as they were.

The apps

PureOpen
macOS · iOS

A Markdown editor for Mac and iPhone that gives each paragraph its own text direction, so documents mixing Hebrew and English read correctly with no setting. Tabs, autosave, offline.
Details
PureWrite
macOS · iOS

A writing environment over a folder of Markdown files: start typing and the sidebar and table of contents fade away, leaving the document alone on screen. Folder-wide search, and every paragraph in its own direction.
Details
PureKanban
macOS · iOS

Task boards stored as plain Markdown files, in a format compatible with the Obsidian Kanban plugin — projects, goals, and a dashboard across all boards.
Details
pureCodex
macOS · Windows

A personal wiki over local Markdown files — wikilinks, backlinks and transclusion, compatible with an Obsidian vault.

Your files, in a format that stays yours

Files, not a database

Each app reads and writes ordinary .md files on disk. There is no import step, no library and no proprietary container — delete the app and the files remain, readable in any editor.

Any sync, or none

Files live where you put them: a local folder, iCloud Drive, Dropbox, a git repository. The apps do not sync and do not need to — they work on files, and files sync.

Hebrew and English in one document

Every paragraph, heading and list item takes its direction from its own first strong character. A mixed document reads correctly with no setting, and nothing is written into the file to make it work.

Native and private

Each app is a Rust binary using the system webview, not an Electron browser. No account, no network calls, no telemetry — what is in your files stays on your device.

Already using Obsidian? Keep using it.

Point a Pure app at the folder your vault already lives in. Nothing is imported and nothing is converted. Obsidian keeps working exactly as it does now, and the Pure app is another window onto the same .md files. They are layers over one folder, not a place to move into. Open whichever one suits the task, and if you stop using a Pure app your vault is exactly as you left it.

Three more that work on the files you already own

The Pure apps are free. The same desk makes a few paid Mac utilities built on the same idea — your files stay yours, on your machine, in a format you can read without us.

Snippet
macOS · iOS

The text you send over and over, on a keyboard you can reach inside any app and in the Mac menu bar. Templates fill their own fields from a message you select.
Mac App Store
Voynich
macOS · iOS

Encrypts a note, a folder, or a whole vault where it sits, into an AES-256-GCM container under the same name. Behind Touch ID, no account, and a documented format that opens without the app.
Mac App Store
RSync Pro
macOS

Keeps your Markdown folder mirrored to a second disk, or to a server of your own over SSH, the moment a file changes. Real rsync, driven from a Mac window.
