settle was designed with the Zettelkasten method in mind. It works primarily
with Markdown.
However, there are a few differences from most other Zettelkasten apps, and that stems from the design principles:
settleis made for humans, for a pleasant note-taking experiencesettleonly manages notes, not editors: settle is a mere note-taking assistant, it doesn't handle file editing- what you see is exactly what you get: all metadata is stored in the notes themselves, and none may be added or removed by using commands, which makes the database a mere convenience - all metadata is inferred from the filesystem.
- projects are only used to formally separate Zettel, but there isn't any hard boundary - any note may reference any other note
- links between Zettel are wiki-style links, which are extremely straightforward.
- no two Zettel should have the same title, even if they are in different projects. This is only to avoid potential ambiguity with links.
