INDXD is a digital, web-based index tool for your analog notebooks.
Ostensibly allows one to digitally index their paper notebooks (page numbers optional). It emails you weekly text updates, so you’ve got a back up of your data if the site/service disappears.
This could potentially be used by those who have analog zettelkasten practices, but want the digital search and some back up of their system.

ᔥ sgtstretch in @Gaby @pimoore so a good friend of mine makes INDXD which is for indexing analog notebooks and being able to find things. I don’t personally use it, but I know @patrickrhone has written about it before. (10/27/2022 17:59:32)
