'gets sharper after every session' assumes you stay consistent with the inputs. is it just me or do these stacks mostly degrade around week 3 when the curation cost catches up?

Obsidian CEO actually released the skill that lets your AI agent run your entire vault for you. It's called obsidian-skills. Install it into Claude Code, Codex, or OpenCode, and your agent can read, create, search, and organize notes directly, plus handle Markdown, Bases, and Canvas files without you touching a thing. This is the missing piece for an AI second brain. Your notes live in Obsidian, and now the agent actually knows how to work them. Want the full picture? We broke down how to build a complete AI second brain from scratch in the article below.

this is pure f*cking treasure Andrej Karpathy just dropped the blueprint for a second brain that writes itself: "Obsidian is the IDE; the LLM is the programmer; the wiki is the codebase" No more re-explaining everything to your AI from zero every time You drop in a source, and your agent reads it, writes the pages, links everything and flags contradictions One source can update 10–15 pages at once Raw sources → LLM Agent → Wiki → Ingest → Query → Lint → Second Brain 95% of people are still uploading files to chatbots and getting answers that vanish The 5% who build this will have a knowledge base that gets smarter every single day Worth more than any $2,000 AI course Bookmark this and build yours tonight Full one-page cheat sheet below ↓

The difference between memory and a second brain... In Hermes you have a memory.md file, but it's not particularly useful for storing a lot of info. Your second brain is a type of memory where you can distil down your raw inputs into insight you can use with AI. If you want to build a second brain with GPT6 Astra, check out the article I put together below.

Andrej Karpathy builds a personal wiki to think with LLMs. I took that idea and went further. Claude Code + Obsidian = an AI that actually knows you. Your goals. Your context. Your history. Not a chatbot. A second brain that remembers. Here's exactly how to build it:

CLAUDE JUST TURNED OBSIDIAN INTO A BRAIN THAT NEVER FORGETS (FOR $0) Someone connected Claude straight to their Obsidian vault. Now the AI reads and writes every note they own. Every client, every idea, every project. Instant recall. Runs on Claude + Obsidian. One evening. Zero code. The numbers are insane: - Notion AI: $10/month forever - A "second brain" course: $500 to $2,000 - An assistant to organize your notes: $3,000/month - This setup: $0 - Time to build: one evening - Skill required: copy the steps The opportunity is even wilder: People sell Notion "second brain" templates for $99 to $499. You just built something better for free, and it never forgets. One free vault can hold the entire memory of your business: clients, content, SOPs, ideas. One person + Claude + Obsidian + one evening = an infinite memory that never forgets. Save and watch the clip.
