// EDITOR'S TAKE
Joplin maps most directly onto the notebook and section hierarchy, with sync to storage you control, though its Markdown editor is stricter than OneNote's free canvas. Affine keeps the freeform feel by mixing pages with an infinite whiteboard, and SiYuan sits between the two with structured documents plus drawing and annotation support.
