Why a vault of Markdown files beats built-in chat memory for AI agents

dSebastien · x · 2026-11-14

dSebastien argues that a vault — a folder of Markdown files — is the best memory system an AI agent can have. Built-in chat memory is proprietary, opaque, and disappears when the product changes; a Markdown folder is portable, inspectable, versioned with git, and editable by you when the agent gets something wrong. You can read what your assistant believes about you, correct it, and diff it. Post ends with a promotion for his personal knowledge management newsletter.
