Capacities: a studio for your mind

If you make heavy use of the room feature here, particularly if you tend to save a single rec to multiple rooms (Powells in both 'bookstores' and 'Portland', for example), your brain might really like Capacities. It's halfwayish between Obsidian and Notion, and better than both, from someone who has tried all three and thinks a lot about PKMs, zettelkasten, note-taking, indexing, library science, etc. It's functional and good and useful and makes me happy in the way that Rec League does.

I absolutely love how compatible it has been with an otherwise very analog and offline existence. The majority of my note-taking and research is on paper, but if there's something from the internet that I'd ever want to reference back to, particularly research for upcoming trips and projects, this is where it lives. I like how a concept is linked to other concepts, and the tag and sort features are intuitive and effective. The solve-the-murder-map-type web of ideas pairs so well with a visual brain. I find that I spend my time actually making and referencing back to notes rather than endlessly tweaking the architecture of my filing system.

AI is an optional and non-default variant that I can't speak to, as it's not something I use at all. The team that runs Capacities is small, responsive, innovative, and Europe-based, with all of the data privacy rights that that brings. It works online and offline, on Apple, Windows, Linux, iOS, Android, etc. The free tier is fully fledged and robust, and I haven't found any limitations.
