I built an automated business OS in Obsidian using Claude + n8n — here's exactly how it works
I've been using Obsidian for a while but always felt like I was just dumping notes into a void. Last few months I rebuilt it from scratch as an actual operating system for my freelance business. Wanted to share what I landed on because it genuinely changed how I work.
The core idea:
Obsidian stores everything in plain text. Claude reads it. n8n activates it. Together they form a loop that gets smarter every week.
What actually runs automatically now:
6AM Morning Briefing — n8n fires three workflows before I wake up. By the time I sit down I have a Project Pulse (what's on track, what's stuck, what needs me today), a Content Brief (three ranked angles with hooks), and an Intelligence Brief (what's happening in my industry that matters). I read all three in five minutes.
Pre-call client briefs — 30 minutes before any client call, the system reads the entire client folder — every interaction, every promise I made, every open issue — and drops a structured brief in my GENERATED folder. Full relationship timeline, suggested agenda, the one thing I need to make sure I say. I haven't walked into an unprepared client call in months.
The Draft Engine — I drop a file in my QUEUE folder named DRAFT-linkedinpost-[topic].md with three bullet points inside. The system reads my voice profile, pulls relevant research, and produces a complete first draft. I edit for 8-10 minutes. Done.
Financial tracking — I write one line in my daily note when money moves. RECEIVED: $X – ClientName, description. The system reads it, updates my ledger, and generates a full financial brief on the 1st of every month. Haven't opened a spreadsheet in three months.
Weekly review — Every Sunday at 8PM n8n reads my entire week and synthesises it into: what moved forward and why, what didn't and the honest reason, one pattern across the whole week, and three priorities for next week ranked by leverage.
The folder structure that makes it work:
The CLAUDE.md file is the secret weapon — it lives in OPERATIONS and every automation reads it before doing anything. It contains your business overview, active client statuses, your writing voice, revenue targets, and a weekly focus section you update every Monday. Without it Claude produces generic output. With it, everything sounds like you wrote it.
The compound effect is the real sell — month one the system is useful but thin. Month six it knows your client relationships at a depth that would take a human employee years to develop. Every interaction logged makes every future brief better.
Happy to answer questions about how any specific part is built. The n8n workflows in particular took some iteration to get right.
