Heptabase is the better pick for visually organizing what you know — infinite whiteboards, linked atomic notes and PDF annotation for mapping ideas. HoverNotes is built for the step before that — it watches videos with you and turns courses, lectures and tutorials into AI study notes automatically, capturing the on-screen code and diagrams, saved to your Obsidian vault.
