Knowfox

Knowfox is a personal knowledge management system with the following features

• Hierarchies. Inspired by Dave Winer's Worldoutline and Fargo, knowledge bases can have a deep structure
• Tags. Where a single hierarchy is not enough, tags can link common topics in the least intrusive way.
• Typed relationships. Sometimes, hierarchies are too strict and tags are too loose. For example, there may be links from authors to books, founders to companies, cause to effect. For this, there are typed, bi-directional relationships.
• Markdown. There are other many similar and nice text formats, but Markdown is simple and popular and has won the race.
• Bookmarking. There is a bookmarklet to take note of websites and mark them for later reading.
• Pictures. Notes have lots of pictures. Mostly screenshots, but some photos or diagrams added as well.
• Privacy. All my notes and pictures are mine and should be visible to no one.
• Simple journalling. As a replacement for Evernote, journaling is painless and well supported. Easy, date-based journalling is a feature I use every day.
• Sharing. Sometimes I want to share a note and its pictures. This is painless and explicit.
• Publishing. Knowledge wants to be communicated sometimes. For this, exporting a sub-tree of a hierarchy as beautiful slide deck, effortlessly, us easily supported.
