It remembers what you figure out, connects it to what you already know,
and answers when you ask.
English | 繁體中文
You solve a hard problem on a Tuesday. Three months later, in a different repo, you solve it again from scratch — because the answer lived in a chat log you'll never find.
This fixes that. Point it at a folder, tell your agent what to remember, and it compiles what you learn into interconnected markdown you own. The pattern comes from Andrej Karpathy's LLM Wiki gist: compile knowledge once and keep it current, instead of asking an LLM the same questions forever or re-running RAG every time.
Your second brain. Your AI agent is how you grow it.
Every skill here is a markdown file that any agent — Claude Code, Cursor, Codex, Windsurf, Gemini CLI, and a dozen more — reads and runs. No runtime, no API keys, no vendor.

pip install obsidian-wiki
obsidian-wiki setup --vault ~/brain
Using uv or pipx? uv tool install obsidian-wiki and pipx install obsidian-wiki work the same way. (Not uvx — see Installation.)
Then open any project in your agent and say "set up my wiki".
Prefer not to touch a terminal? Give your agent this and it'll do the whole thing:
https://github.com/Ar9av/obsidian-wiki — set up my wiki
Other paths — git clone, Skills CLI, multiple vaults → Installation
What you actually do
Feed it. Anything text-shaped: docs, PDFs, chat exports, meeting transcripts, screenshots, URLs.
/wiki-ingest ~/research
/wiki-update # distill the repo you're standing in (code-graph aware)
/wiki-capture # save this conversation
/wiki-history-ingest claude # mine everything you've ever asked Claude
Ask it. Answers come back with [[wikilink]] citations, not vibes.
/wiki-query what do I know about rate limiting?
/wiki-narrate MCP security # a cited briefing on a topic
/wiki-digest week # what did I learn this week?
Find that session you can't name.
obsidian-wiki sessions-build
obsidian-wiki sessions-query "the auth bug with the weird retry loop"
Keep it honest. The vault gets messy on its own; these clean it.
/wiki-lint # broken links, orphans, contradictions
/wiki-dedup # "RSC" and "React Server Components" are one page now
/cross-linker # weave new pages into the graph
/wiki-status # what's ingested, what's pending, where the hubs are
