Honestly with LLMs you don't need an Obsidian anymore. You can just use neovim or emacs. Every feature you need, like search, or linking can be done via plugins or shell commands.
Because before LLMs you couldn't use neovim? Emacs's search feature was vide coded in 2024? How is the first half of your comment even related to the second half.
I use Obsidian to view a series of markdown files I am generating / working on with a LLM - a rendered interface if you will with pointing and clicking
I was using vimwiki with a ton of plugins for many years before Obsidian came along. It was very nice to be able to open all of my notes in a UI made for editing them.
