We think simple tools can help us all improve the quality of information on the Internet and in the greater world around us.
Our team is building an open platform for discussion on the web. It leverages annotation to enable sentence-level critique or note-taking on top of news, blogs, scientific articles, books, terms of service, ballot initiatives, legislation and more. Everything we build is guided by our principles. In particular that it be free, open, non-profit, neutral and lasting to name a few.
We create software, push for standards, and foster community.
We are a non-profit organization, funded through the generosity of the Knight, Mellon, Shuttleworth, Sloan and Helmsley Foundations– and through the support of hundreds of individuals like yourself that want to see this idea come to fruition. You can view our tax returns here.
Our efforts are based on the Annotator project, which we are principal contributors to, and annotation standards for digital documents being developed by the W3C Web Annotation Working Group. We are partnering broadly with developers, publishers, academic institutions, researchers, and individuals to develop a platform for the next generation of read-write Web applications. You can follow our development progress on our roadmap.

Here’s a presentation at the 2013 Personal Democracy Forum that provides a little more context for our project.
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library.
If you need to convert files from one markup format into another, pandoc is your swiss-army knife. Need to generate a man page from a markdown file? No problem. LaTeX to Docbook? Sure. HTML to MediaWiki? Yes, that too. Pandoc can read markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write plain text, markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, EPUB ebooks, and S5 and Slidy HTML slide shows. PDF output (via LaTeX) is also supported with the included markdown2pdf wrapper script.
A second brain, for you, forever.
The human brain is non-linear: we jump from idea to idea, all the time. Your second brain should work the same.
In Obsidian, making and following [[connections]] is frictionless. Tend to your notes like a gardener; at the end of the day, sit back and marvel at your own knowledge graph.
- You 100% own your data: Obsidian uses a local folder of Markdown files
- Wiki-style links between pages
- Graph view of the relationship between all your notes
- Jump between notes with keyboard only
- Flexible plugin system, you only need to enable the ones that matter to you. Some plugins include:
- In-app PDF viewer
- Audio player
- Use ![[image.png]] syntax to embed a multimedia file (currently images and audio, more to come)
