I figure I should ask this before I start writing my own...
I'm looking for an app that I can use as a repository of information about a subject. Here's the sort of features I want:
- Individual "articles" where I can write about the things I've learned/discovered/theorized
- Be able to tag these articles with keywords (like tags on this question)
- Be able to group these articles into folders of related stuff.
- Smart folders would be especially nice.
- Be able to write these articles in a simple format. Markdown would be wonderful.
- Be able to search through the articles to find stuff/Spotlight integration.
- Must be a native Mac app. Not a web app. Having a companion iOS app would be a major bonus.
- Article versioning would be nice.
- Automatically detecting related articles (even a simple algorithm) would be nice.
Basically, I think I want an off-line, personal Wikipedia that I can write in Markdown. Do any of you know of an app (or apps) that does what I'm looking for?
