The backstory
Obsidian is a local-first markdown knowledge base: your notes are plain files on your own disk, linked into a personal wiki. AI note tools and Claude's memory can summarize and recall, but Obsidian's whole appeal is ownership and privacy, no lock-in, no cloud required, and AI is optional through community plugins. That inverts the usual threat. It survived because you own the files and control whether AI touches them at all, which is precisely what its users want.
