We build tools for a future you own.

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.

The work

InkStream

A desktop home for serious writing. Three editing modes, Git history, citations, linked notes, and mathematical typesetting.

Pillowtome

A local-first reader for Windows and Android, with Chinese text conversion, annotations, in-book search, and self-hosted WebDAV sync.

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.

Build with us

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 mark, in plain text

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