This quote from G.R.R. Martin, the author of A Song of Ice and Fire and other novels, offers a good illustration of the key difference between Roam and Notion: “I think there are two types of writers, the architects and the gardeners. The architects plan everything ahead of time, like an architect building a house. They know how many rooms are going to be in the house, what kind of roof they’re going to have, where the wires are going to run, what kind of plumbing there’s going to be. They have the whole thing designed and blueprinted out before they even nail the first board up. The gardeners dig a hole, drop in a seed and water it. They kind of know what seed it is, they know if planted a fantasy seed or mystery seed or whatever. But as the plant comes up and they water it, they don’t know how many branches it’s going to have, they find out as it grows. And I’m much more a gardener than an architect.”
A good way to think about Roam vs. Notion.
Notion is more for the "architects" and Roam is better suited for the "gardeners."
The thing is, we ALL have parts of our life that require precision and parts where we need creativity. Both tools might be used successfully.
