I turned my Obsidian vault into an AI-powered work OS — open source, free
Hey IH 👋,
I'm building ObsidianOS for people like us, founders and builders who live in meetings, emails, and task lists, and don't have time to manually organize it all.
It's open source (MIT), free forever, no catch. Just clone, fill in one file with your name and timezone, and you're set.
What it is: an Obsidian vault wired with AI agent skills that you run via slash commands. Think of it as an agentic layer on top of your notes.
What makes it worth trying:
• /meeting — type it, pick from your Google Calendar, and it creates a structured note. After the meeting, /meeting wrap caches the AI transcript, resolves participants to wikilinks, and extracts follow-up tasks. One command, four steps done.
• /recap this week — pulls from your vault notes, Gmail, and Calendar to produce a weekly recap: highlights, open items, insights, activity summary. I use it every Friday to see what actually happened vs. what I planned.
• /followup-todos — reads a meeting note and extracts action items as Obsidian Tasks checkboxes with assignees and priorities. No more "I think someone said they'd do that."
The part I think IH founders will appreciate most: it's agent-agnostic. Works with Cursor, Claude Code, OpenCode, or any MCP-compatible client. You're not locked into one AI vendor. The skills are just markdown files that describe workflows, any agent can read and execute them.
Everything stays local in your vault. No SaaS, no sync service, no data leaving your machine. Your meeting transcripts, emails, and tasks live in plain markdown files you own.
I've been using this daily for my own work, managing an engineering team across standups, 1:1s, product reviews, and tech briefs. It's been genuinely addictive watching an agent handle the busywork.
Come kick the tires. I'd love feedback from people who run their own stuff. What workflows eat your time? What would make this something you actually keep using?
