## Summary

A developer presents an open-source tool that makes knowledge bases usable for both AI agents and humans — inspired by Andrej Karpathy's "Second Brain" vision. The system connects to various data sources like Obsidian vaults, PDFs and screenshots, extracts contents and makes them retrievable. Access controls allow granular permissions so agents can read from certain sources but only write to defined areas. In enterprise contexts, this addresses a common challenge of connecting AI with disparate knowledge sources.

## Nauti's Take

The "Second Brain for agents and humans" concept hits a real pain point — anyone working with Obsidian, Notion or similar tools knows the problem: your knowledge exists but your agent cannot access it. Launching right after Karpathy's viral tweet is strategically smart but also risky: hype-driven launches have short lifespans. Nauti says: compelling approach with genuine utility, but retrieval quality will make or break it.
