Over the past couple of weeks, I spent some time pulling all of my notes from various sources, converting them to Markdown (if not already) and then using Claude Cowork to clean up and organize these notes. I removed duplicates, updated metadata, fixed links, and applied an assortment of other fixes. Claude Cowork made the process quite simple.
While I still have a local copy in Markdown, I did import all of these notes into Apple Notes. Now they're all accessible through search or even by Siri AI, which has been quite handy!
