Spoke at Hermes AI Agent Night: The AI Operating System at SGInnovate tonight, with thanks to Lionel from The AI Capitol and SGInnovate for hosting.
I shared how I use Obsidian as a company wiki and demoed it for sales and GTM professionals: context, meeting notes and follow-ups all in one local database. I also walked through Karpathy's LLM Wiki, modified with Dr Vivian Balakrishnan's OKF idea to save tokens as a rulebook for my agents' second brain.
Over the last few weeks the same questions kept coming up: what do I use as my second brain, and how do I handle data privacy and security. My Obsidian wiki is only reachable by devices I let onto my secure Tailscale network. For confidential data, I run local models to turn messy inputs (emails, voice notes, and so on) into a structured Karpathy-style wiki, building it from scratch on the machine with no third-party LLM or service looking at the data.
We keep seeing models go off the rails in the news, acting without a human in the loop when instructions are not bounded by clear safeguards. Full control over how data is used is not a nice-to-have, it is a necessity, and it matters most for enterprises in regulated industries.
Good to see attendees in the community already running Obsidian fully local and starting to sync devices with the free, community-built LiveSync plugin. My slide deck is here: obsidian.procss.online.
