98-minute guide: turning an Obsidian vault into an AI-powered personal operating system

dSebastien · x · 2026-09-03

Sebastien Dubois published a 98-minute mega-guide on Obsidian automation, from Templater templates to running AI agents on top of your vault.
Core argument: an Obsidian vault is just local Markdown files (his has 20,000+ notes), so scripts, Git, cron jobs and AI agents can read/write freely — making it an ideal base layer for a personal AI "operating system," unlike tools that lock data in their databases.
Covers the File over app principle and a full map of plugin combos (Templater, QuickAdd, Meta Bind, etc.).
In follow-up tweets he shares experiments: Meta Bind buttons, a custom TPL Action Retype (migrate note types without losing metadata), TPL Dispatcher (apply templates, ask questions, file notes), and a planned "OSK Quick Actions" sidebar note.
