// EDITOR'S TAKE
AppFlowy is the closest structural clone, with Notion-style blocks, boards and database views, while Affine adds an infinite whiteboard that Notion has never had. Outline is the smarter choice if what you actually want is a fast team wiki, since it drops databases entirely in exchange for much simpler operation and search that just works.
