AI comparison summary

TL;DR: Both are privacy-focused note-taking apps with free tiers, but Logseq is fully open-source while Obsidian is proprietary. Logseq uses an outliner-based approach (think Roam Research) where everything is organized as nested bullets, whereas Obsidian uses traditional page-based Markdown editing. Obsidian has a much larger plugin ecosystem and more polished UI, while Logseq appeals to users who prioritize open-source software and prefer outliner-style workflows.
