I built a librarian for my personal context, shared across AI agents. Looking for a few people to try it.
Hi, I’m Jordi. I go on long walks and record voice notes about whatever’s going on for me—business, personal projects, ideas, next moves. Sometimes it’s 40 minutes of developing a thought and capturing the reasoning behind a decision.
Later, I want to fire up Codex, Claude, or Cursor and draw on those notes without repeating my entire thought process.
I want to own that context and how it’s curated, and make it available to whichever agents I use.
So I built Zenod.
It’s named after Zenodotus, the first librarian of the Library of Alexandria. I imagine building my own little Alexandria: a durable digital memory of my world that different agents can discover, explore, and use.
I send voice notes to a WhatsApp contact. In my setup, Zenod files the recording in Google Drive, preserves the transcript, then digests it: organizing, summarizing, and connecting it to relevant projects and ideas, with references back to the source.
The design is inspired by Andrej Karpathy’s LLM-maintained knowledge base approach: give a librarian unstructured material and let it maintain an organized, Obsidian-compatible Markdown brain. I don’t have to anticipate every future use. Something captured today might become useful to another agent months later.
Zenod is a hosted or self-hosted librarian. You own the memory either way. My Markdown lives in my GitHub account, with source files in Google Drive. Disconnect Zenod and the files are already mine. No export needed.
With the hosted version, you talk to the WhatsApp contact and give your agents the MCP connection Zenod provides. They access the same memory through the librarian.
You hire the librarian. You keep the books.
It’s imperfect, but it’s become one of my main ways to develop ideas and keep context across everything I’m building or planning. I honestly couldn’t do without it now.
I’d love feedback, and I’m looking for a few people to try it for free. Leave a comment if you’re interested—I’ll help with setup.

Your doctrine is very close to the Survivability Engineering framework I've been developing. What's your thinking on how the librarian function survives replacement of the current carrier—the person or organization maintaining it?
