The Notion system that I'm building has two components to it.
Within the private workspace you'll be able to store your completed sketchnotes, track your sketchnotes-in-progress, and work on projects that involve combining sketchnotes for articles, presentations, or any other creative endeavor.
Within the public portfolio you'll be able to share your sketchnotes (only those you want to be public) and written reflections on a public-facing website (still using Notion - no need to buy a domain or worry about hosting), along with any other information you'd like to share with folks who come across your work.
