Obsidian has been the center of my productivity system. It’s where I capture ideas, plan projects, research new topics, and build long-term knowledge. But as AI tools have become more capable, I started wondering if they could do more than just answer questions or summarize notes. Could an AI actually help me make better use of everything I’d already written? To find out, I gave Claude read-only access to my Obsidian vault, and the results were far more useful than I expected.
