A newer take that sits between Notion and Obsidian: instead of pages in folders, everything is an object, a person, a book, a meeting, a note, that you link together into a connected daily notebook. Built-in AI helps you retrieve and connect what you have saved, and a daily note encourages the habit.
Being younger, its apps and offline support are still maturing, and the object-based way of thinking takes adjustment. For someone who wants a modern, networked notebook without assembling Obsidian themselves, it is the most interesting of the new arrivals.
