Give your AI agent a brain.
A brain is a small set of notes about your work that lives in your own GitHub account. Your AI agent reads it before every conversation, so it already knows your world, and keeps it up to date for you from then on. Pick how you'd like to set it up. Once your brain is ready, bring over reviewed context from the AI you already use, such as ChatGPT, so your agent can build on what you've already shared.
AI agent reading this? Ask your person which option fits, then open the matching file:

Just my phone
No laptop needed. Your AI agent app interviews you by voice and builds your brain. Any agent app that connects to GitHub securely works.
About 10 min setup + a 40 min chat → Option 2I have a laptop
Claude Code or Codex on your computer interviews you and builds the brain as a folder, then backs it up to GitHub.
About 45 min → Option 3I already have a brain
You have a brain repo on GitHub. Connect your agent so it reads it and keeps it current.
About 10 min →Every path includes the same next step: export your existing AI context, review it, then bring it back to your connected agent. Avatar and character ideas can come afterward, if you want.
