astrolabe

Astrolabe is an instrument for people who read seriously and write from what they read. It runs as one small Node.js process over an ordinary folder of Markdown and LaTeX files, with everything it knows about your notes read directly from those files. The application provides a live-preview editor with wikilinks and backlinks; a graph view; search that understands Arabic letter forms and diacritics; a book reader driven by vim keys that cites highlights into the note beside it; trackers for books, games, and courses; sigils (daily plans) with streaks and heatmaps; orbits (spaced repetition decks); drawing tools via Excalidraw; LaTeX notes that compile; and a blog publishing system. It is designed to be bilingual by default, with Arabic and English as equal renderings of the same product, featuring mirrored shells, Hijri date support, right-to-left prose behavior in the editor, reading view, and published pages. The vault opens from any browser on your network — phone, laptop, or desktop app are three windows on one vault. No data is converted, wrapped, or stored elsewhere; delete the app tomorrow and the folder remains untouched.
