Reviewer scorecard
“The free tier is genuinely usable. Rare for this category.”
“My entire content pipeline runs through Obsidian. Research notes link to article drafts link to published pieces. The graph view shows connections I would have missed.”
“Fast, reliable, and the docs are actually good. Ship.”
“Local Markdown files mean I own my data forever. The plugin API is powerful — I built custom integrations for my dev workflow. Git sync works perfectly.”
“The learning curve is real — you need to invest time building your system. But once set up, it is the most powerful personal knowledge tool available.”
