Bookmark: WikidPad - wiki notebook for Windows/Linux/Mac OS
This installed just fine on Win 10. The instructions for Linux and Mac look more complicated. I have to say this is pretty damn cool. I would call this more of a wiki notebook, “pad” sounds too small. You can make some extensive, many pages of, notes on this just like a notebook. With the WikiWord linking this could be a great project notebook.
I also think this could make an interesting personal journal.
Free. I could see this as a way to learn the gist of wiki usage prior to installing one on a web account.
The negative is no cloud storage, no sync between computers.
