Software for thinking, creating, and working with machines. We start with a page to write, a book to read, an idea worth building. The tools that shape your work should leave you in control.
A desktop home for serious writing. Three editing modes, Git history, citations, linked notes, and mathematical typesetting.
A local-first reader for Windows and Android, with Chinese text conversion, annotations, in-book search, and self-hosted WebDAV sync.

WHAT COMES NEXT <+
We care about software you can understand, workflows you can change, and work you can carry with you. That is the direction we build toward.
Start with a project. Read its docs. Open an issue with something concrete: a question, a rough edge, or a better way to do the work. Follow its contribution and license terms when making changes.

The Penrose triangle is our reminder to look again. Three beams. One continuous loop. A shape that asks for another way of seeing.
