GoKawiilObsidian Canvas and Heptabase diverge sharply in how they store notes, analysis finds
A technical comparison contrasts how Obsidian Canvas and Heptabase handle spatial note-taking. Obsidian Canvas saves layouts as JSON-based .canvas files that embed existing markdown notes, while Heptabase treats cards as central, reusable entities that can appear across multiple whiteboards simultaneously. The analysis notes that a connecting line in Obsidian only records visual position, whereas in Heptabase it creates a relationship the linked cards retain and can surface elsewhere.
