How I Use AI
The system
Every project, every idea, every session lives in one Obsidian vault. Claude reads it at the start of a session instead of starting blank, writes new material back in as linked notes, and runs a weekly pass that surfaces contradictions and gaps I would never find by hand. Codex runs the same schema when I use it for project too.
In plain words
A second brain is just a notes app that an AI actually reads, instead of a chat window that forgets everything the moment I close it. Every project I'm building, every idea, every decision goes into one place. Before Claude helps me with anything, it reads that place first -- so I'm not re-explaining my own apps to it every single time.
A macOS voice assistant, always listening for a wake word, never for anything else. Double-clap or say "hey Jarvis" and an offline model wakes it up. Claude Haiku holds the conversation and decides which of ten skills to run: weather, calendar, stocks, timers, opening an app. ElevenLabs speaks the answer back,
In progress
An AI rehearsal coach for actors prepping self-tape auditions. Upload a script and an AI reader plays every other character while the app listens for your cue and advances the scene on its own.
An entrepreneurship class pitch. WiFi-connected helmet that lights up and plays a song the instant your team scores. The ESP32 build and its companion app were both working the day after the pitch, built with Claude Code.
An open-source local voice app I didn't build, but the shipped version crashed on almost every use. I cloned the source, tracked the crash to a GPU threading bug, and rebuilt its menu bar app from scratch in native SwiftUI.
Claude, Codex, ChatGPT, Obsidian, Terminal, Xcode, Notion -> different tools, same vault, same habit of turning a conversation into something that keeps running.
