The vault you start this weekend becomes the one thing your competitors cannot scrape, clone, or out-prompt their way around in 2026.
7 million people read @CyrilXBT's Obsidian guide.
341,000 read @DamiDefi's "Claude knows my thinking better than I do."
I read both. I analyzed both. I built on top of both for the last 6 months.
Here's what I'd add.
The folder structure matters. The tags matter. The plugins matter.
Cyril and Dami nailed all of that - you should follow their guides line by line.
But there's one layer above their setups that almost nobody is centering yet:
Stop thinking of Obsidian as a vault.
Start thinking of it as the training set you're quietly building on yourself.
Six months in, the vault you build this weekend becomes the one thing your competitors cannot copy, scrape, or out-prompt their way around.
Not the stack. Not the prompts. Not the model.
The corpus.
This is how you build it.
