Second Brain
A self-hosted AI that reads what you save, builds your knowledge base overnight, and briefs you every morning. Runs on a $35 Raspberry Pi.
Save a link from your phone at midnight. Wake up to a wiki article, cross-linked with everything you already know, with a morning briefing waiting in Telegram.
Not a RAG. Not a chatbot with memory. Not a tool you have to open. An autonomous system that compounds your knowledge while you sleep.
How it feels
Monday night โ you save three articles from your phone via Telegram.
Tuesday 07:00 โ Pi compiles them into wiki articles while you sleep.
Tuesday 08:00 โ Telegram briefing arrives: what was compiled, what needs review,
any tasks due today.
Tuesday morning โ you open http://second-brain:4321 from any device.
Everything is already there.
No laptop open. No command to run. No maintenance.
