Obsidian and Codex as a record of my day

I’ve been using Obsidian with Codex for a while now, mostly as a way to keep track of all the stuff that happens around my actual project work. Obsidian is basically a notes app that stores everything locally and lets you organize and link information together, which makes it a really good fit for this.

I’m still using my coding agent and the repo as the source of truth for the projects themselves. That’s where the code, plans, project context, and all of that lives. I don’t really want to duplicate that stuff in Obsidian.

What I am putting in Obsidian is meeting recordings, transcriptions, notes, decisions, follow-ups, and my to-do list. Basically all the stuff that happens during the day that I’m probably going to need again later.

That’s been really useful because Codex can work across all of it. I can ask what we talked about in a meeting, what I said I was going to follow up on, what decisions I made last week, or just what I still need to get done.

It’s basically becoming a second brain for me. More of a digital assistant with a really good archive of my day-to-day work than another place I have to manually keep organized.
