Two open-source tools are highlighted for building AI-powered personal knowledge systems. Rowboat (15K GitHub stars) is an open-source 'second brain' inspired by Karpathy's LLM wiki concept — it runs background agents that index emails, meetings, and notes into a self-updating knowledge graph, with work surfaces like an email client, meeting note taker, and code mode. Separately, Google's Agents CLI is covered as a unified interface for the full agentic engineering lifecycle, covering scaffolding, evaluation, and deployment of ADK agents across model providers and infrastructure targets.
