Overview
ExoBrain is an open-source CLI tool that turns Obsidian into an AI-powered knowledge system. Distributed as an npm package, it sets up in under 5 minutes and runs entirely on your machine — no subscriptions, no cloud lock-in, just plain Markdown you own.
The Problem
Most note-taking apps either require manual curation (time-consuming) or lock your data in proprietary formats. Staying on top of daily news, summarising content, and building a connected knowledge base takes hours every week.
The Solution
A single npx exobrain command wires Claude AI into your existing Obsidian vault via a macOS launchd job, automating the tedious parts: morning briefings are ready when you wake up, and any YouTube video, PDF or podcast becomes a structured note in seconds.
Key Features
- —Daily briefings — weather + world/AI/macro/local news written directly into your vault each morning
- —Content summariser — converts YouTube videos, podcasts, and PDFs into structured Wikipedia-style notes
- —People profiles — auto-generates profiles for public figures mentioned in your content
- —Gmail & Google Calendar integration for a unified daily context (v1.1)
- —All data stored as plain Markdown — fully portable, no vendor lock-in
