Turn your notes into a second brain, with AI inside.
Obsidian is where knowledge goes to live. The terminal is where it comes back to work — with local search, persistent memory and research pipelines.
What a second brain actually is
A second brain is a personal knowledge base you can trust — notes, research, project files — organized so you can find and reuse them later. Obsidian is one of the most popular tools for it because everything is plain Markdown on your disk, forever yours.
Add an AI terminal and the second brain starts answering back: you can search it, ask questions against it, and file research into it without leaving the keyboard.
Search your vault without using tokens
The /lib and /libsearch workflows give you "librarian knowledge" of your Obsidian vault — a local search database that does not consume LLM tokens. libsearch does a deep fuzzy search of file contents (fuzzy RAG), so you can find that half-remembered note instantly.
Persistent memory across sessions
memory_search— recall prior work at the start of a task.memory_remember— save outcomes, corrections and preferences.- Session logs — every session is a durable artifact, resumable days later.
- Deliver to Obsidian — research and briefs write straight into your vault.
That continuity is what makes the terminal feel like an extension of your own thinking, not a chat window you restart each morning.
From notes to published work
Pair your second brain with the Obsidian → Ghost publishing workflow and your research vault becomes a content engine: draft in Obsidian, run the SEO audit, publish to Ghost — all from the terminal.
Start small with your first hour, then explore research workflows.
