I'm a philosopher, mathematician, and technologist in the San Francisco Bay Area. I create free and open-source productivity tools and write documentation for open source projects.

I build unofficial editor extensions for Standard Notes, a free, open-source, and end-to-end encrypted notes app:

• Append Editor (demo, docs) - Write GitHub Flavored Markdown via four different editing modes: Plain Textarea with spell check, in-line formatting provided by CodeMirror, what-you-see-is-what-you-get live formatting provided by the Rich Markdown Editor developed by Outline, and in-line syntax highlighting provided by the Monaco Editor. In addition to GFM, the Plain Textarea, CodeMirror, and Monaco modes support KaTeX, table of contents, footnotes, in-line HTML, and emoji codes. The Monaco mode also supports autocompletion, search and replace, and syntax highlighting for over 60 programming languages. The Append Editor has built-in support for printing notes and per-note font sizes, font families, and custom CSS.
• Flashcard Editor (demo, docs) - Study flashcards in private with KaTeX and Markdown.
• Marp Editor (demo, docs) - Create presentation slides with Marp and Marpit Markdown.
• Music Editor (demo, docs) - Write music with VexTab and VexFlow.

Maintaining and developing new features for each editor takes a considerable amount of time. Sponsorship would make it more sustainable for me to work on more open source projects. I will use the funds for domains, server hosting, developer tools, and general life supplies. I'll also pay it forward by sponsoring developers whose work my work depends on. If you use any of my projects or just like what I'm doing, please consider sponsoring me.
