Su: notes and a reader you can handwrite on

To mark up Markdown by hand like paper, read other languages without switching to a translator, and keep my data in my own hands, I made Su and Su Reader.

Why I made it

Three things kept bothering me when taking notes and reading. First, Markdown is fast to type, but you can’t circle or scribble on it the way you can on paper. Second, reading in another language meant switching back and forth between the original and a translator, which is tiring. Third, I didn’t want to hand all my notes and books to a cloud service. To fix all three, I made the Su apps.

Su

Su is a Markdown notes app that renders as you type. You can handwrite, circle and annotate right on the text, and folders sync across devices.

Su Reader

Su Reader is a local-first reader. EPUB, PDF, MOBI, comics, TXT, Markdown and web articles all go on one shelf. Web pages in other languages can be translated paragraph by paragraph and read beside the original; Japanese can be set vertically with furigana; and you can handwrite notes in six colours too. Reading progress and notes sync across devices.

Today

Su and Su Reader (macOS beta) are at then.md.
