You explain yourself to ChatGPT. Then again to Claude. Then again to Gemini.
What you teach one AI stays locked inside that AI. Open a different one, and it has never met you.
I’ve watched folks spend 20 minutes of every session rebuilding context an AI should already have. Multiply that across tools, across days, across a year — it’s weeks of your life spent introducing yourself to software.
There’s a fix. It’s embarrassingly simple: a folder of Markdown files that you own, that every AI can read.
Back in May, I showed you how to solve this for one tool in Claude Code Memory 101 — auto memory, MEMORY.md, the works. Today we solve the bigger problem: memory that isn’t trapped in any single tool. One folder. Every AI.
I’ll show you how to build it in 15 minutes, how to keep it from rotting, and — the part almost nobody covers — how to make multiple AI agents share the same memory without stepping on each other.
