In this video I walk you through Obsidian, which I think of as your personal digital library — a place to keep notes, research, genealogy finds, hobby ideas, and life projects without handing everything over to a big corporate cloud. What makes Obsidian different is that your notes live as local files on your device, so you stay in control. I show you how to download Obsidian, create your first “vault,” and start building a simple system you can grow at your own pace. I also cover how to sync Obsidian across Windows, Mac, Linux, and mobile without paying for a subscription by using Dropbox along with the free Remotely Save approach. If you like saving articles for later, I demonstrate how the Obsidian Web Clipper can grab full articles quickly so they land right in your vault. And because so many of you are into family history, I explain why genealogists love Obsidian as a “second brain,” plus how it can work alongside genealogy software like RootsMagic. By the end, you’ll have a practical, private, organized knowledge system for things like trip planning, gratitude logs, household tracking, and more.
