LiquidText: A tool for academical note taking
I am more and more reluctant to use any note taking app. Ideally, notes I take on  the book I am reading today should still be available to me in 20 years. No app can offer that kind of guarantee. I switched to using plaintext files, and do not look back. The only thing one needs is to have a clear workflow to make sure notes remain accessible and useful. I like the Zettelkasten method for this (see eg https://zettelkasten.de, no affiliation).Not to criticize this app in particular, I actually quite like the concepts listed (which remind me of the Zettelkasten idea). Just the whole idea of keeping my thoughts in an app. Even if it does allow to export the data, it is probably in a format that is difficult to use outside of the app, and thus close to useless.
