I've been using Roam Research lately to facilitate writing. Every article I'm working recently has started as simple notes in Roam, and grew by using Roam's features for linking and interconnecting ideas. Something about the way Roam is built facilitates ease of writing and overcoming writer's block. It gets me excited to write for writing's sake, as a form of thinking, and gives tons of resources to easily incorporate previously written thoughts or generate new ideas because of it's ability to seamlessly network your thoughts.
