Jason Liu discusses his use of Obsidian as a knowledge base for Codex, with his 'Vault' project serving as the primary interface. He clarifies that Obsidian primarily stores markdown files, and while the visual aspect is useful, the AI agent uses it mainly for context.

“But generally Obsidian is just the structure that I use. Um, it's very rare that I actually open things in Obsidian. It's mostly just in context for my for my agent, but, uh, from time to time, it's definitely beneficial to, uh, set that up.”
“Yeah, it's basically all just markdown files. Um, I have a directory for different projects, I have a directory for different notes. I have my daily notes and my preferences.”
