A note-taking app that I’ve just started using is Obsidian. I use Obsidian to capture notes and ideas as I’m reading. I’ve always wanted a better system than index cards or a notebook to store notes and thoughts — a program that would be searchable so I could easily find an idea, illustration or story. Although I’ve just started using it, it’s easy to enter notes into Obsidian and I can tag everything to make it searchable. My favorite feature about Obsidian is the Graph View, a big map that reflects how my various notes and ideas merge and connect around common tags. For instance, if I entered three different notes that I tagged with the theme of “Sabbath,” all three notes would appear connected by dots. If I click on the connected dots, they take me to all the notes I collected on “Sabbath.” Obsidian can be downloaded from the Apple’s App Store or Google Play. I use the free version.
