A step by step guide to building a three-agent personal intelligence system that reads your notes, monitors the web, maintains a private wiki, and delivers daily and weekly briefings to your inbox. The thinking behind why I built this is in the companion post: My Personal AI Brain. What you’ll build: A daily email digest grounded in your Obsidian vault and calendar A nightly wiki update that maps your active topics and enriches them with web research A weekly review that closes the week and opens the next one A private, secured website that hosts your living knowledge base Time to set up: 2-3 hours Running cost: $0 (runs on your existing Claude subscription, Resend free tier covers the email volume) Infrastructure: Cowork, Cloudflare (free tier), Obsidian (iCloud sync) ...

Something broke in the last two years. The pace of change in AI alone has reached a frequency that no person can track without a system: new models, new frameworks, new paradigms, new competitive moves. Add to that the normal demands of a senior role: strategy documents, stakeholder alignment, product decisions, customer conversations. Add personal projects. Add family. Add the nagging sense that something important happened while you were handling something else. ...

I have a confession. For the past two years I have been subscribed to more newsletters than I will ever read, following more RSS feeds than I check, and saving more articles than I open. Every morning I sit down with a vague sense that something important happened and I missed it. The problem is not a lack of information. It is too much of it. AI, AI governance, product leadership, agents, MCP, new tools, the space moves fast and the signal-to-noise ratio is brutal. Miss a day and you feel behind. Read everything and you feel buried. There is no good default. ...

Every senior professional I know has the same problem. Too many newsletters. Too many feeds. Too many tabs open. And somehow, despite consuming more information than ever, the feeling that you’re missing the things that actually matter. I built the Personal Executive Briefing Agent to solve this for myself. It runs every night, collects signals from Gmail, RSS feeds, Reddit, and GitHub, scores each item against my actual priorities, and delivers one email every morning with the small number of things that genuinely deserve my attention – and exactly why each one matters to me specifically. ...

The idea of a “second brain” is simple. An external place to put thoughts, notes, ideas, and fragments of work, so your actual brain can focus on thinking and deciding instead of remembering. In theory, this is how knowledge compounds instead of disappearing. I have liked this idea for a long time. It is why I used Microsoft OneNote for years, and later moved to Obsidian. What I never liked was how much work these systems require in order to be useful. ...
