Getting better every day!
Capacities is an excellent tool for knowledge management designed for individual use. It is non-hierarchical like Obsidian, and in that sense is superior to good old Notion, if it comes for personal use. You can share content but is not designed for team work.
I use Capacities to manage papers and academic work. Also ideas, benchmark research, daily notes, and administration. It is a very powerful tool that feels very flexible and neat.
I prefer Capacities over Obsidian because the latter requires constant revision and maintenance. And because Obsidian offers so many plug-ins, you always get the feeling that you could get a better workaround to improve your note-capturing. Capacities in this sense is a curated experience: once you learn to use it, you make the best out of it, and slowly you get new implementations. The company is very attentive to user feedback.
I hope more people discover the power of Capacities.
