AI-Assisted Second Brain with Obsidian and Claude Code

Practical workflows for building a second brain using Obsidian and Claude Code are emerging. One example features a Karpathy/Flanagan folder structure and daily logs for marketing; another describes a 'permanent brain' approach outside the vault. A new article shows how to ditch Notion entirely by using Claude Code and markdown files to replicate database behavior, offering a lightweight, plain-file alternative for structured note collections. All emphasize transparency over built-in AI memory and represent a growing trend of integrating AI into PKM without losing framework grounding.
