Reviewer scorecard
“Spaces changed how I work. Work tabs in one space, personal in another, client projects each get their own. Context switching without tab chaos.”
“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.”
“Arc is beautiful but the company pivoted to a new product. Updates have slowed. The future is uncertain. Switching browsers is a big commitment for an uncertain product.”
“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.”
“The dev tools work fine since it is Chromium-based. Boosts for customizing internal tools are useful. The command bar is faster than Chrome omnibox.”
“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.”
