Software list

There are numerous digital Zettelkasten programs available. This note collects links and pointers for choosing the right one. For comparision, see Software comparison.

Note that it is likely that the tool you use doesn’t really matter all that much. The original Zettelkasten was a huge stack of paper slips and even that worked great. There is one case where the choice of the tool has a huge impact, namely the case where the tool you use is discontinued. To avoid being left with a stack of 5000 notes that you can no longer access, prefer tools that export/save to common formats, like txt files.
