Your second brain can grow on its own from then on.
Many people's note apps will eventually become "electronic cemeteries."
Collect hundreds or thousands of pieces of content, but they are not organized or related, and cannot be found when needed.
Notion is convenient, but the data is stored in the platform database;Obsidian gives you a free Markdown file, but you need to maintain your own knowledge structure.
The Claude + Obsidian solution is to let AI help you complete the sorting work.
You only need to throw in one piece of material, and Claude will automatically:
- reading content
- Extract characters, opinions, concepts
- Establish knowledge links
- Generating Wiki Page
- Archive to the Obsidian Knowledge Base
Eventually form a Markdown second brain of his own.
After a few months, you can ask it directly, and it will look for answers from what you have read and quote the corresponding page.
Knowledge continues to compound interest growth like interest.
1. Installation method
2 lines of command, 2 minutes to build:
git clone https://github.com/AgriciDaniel/claude-obsidian
cd claude-obsidian && bash bin/setup-vault.sh
The script automatically configures:
- Atlas view
- CSS style
- Wiki structure
- Basic knowledge base template
Then open Obsidian:
Manage Vaults → Open folder as vault → Select the claude-obsidian folder.
Open Claude Code in the same directory and enter:
/wiki
Claude would ask:
"What is this knowledge base used for?"
After answering, it will automatically build the complete structure.
2. You can also install Claude plug-ins
If you don't want to clone the warehouse, you can install it directly:
claude plugin marketplace add AgriciDaniel/claude-obsidian
claude plugin install claude-obsidian@agricidaniel-claude-obsidian
Confirm:
claude plugin list
Any subsequent Claude session input:
/wiki
ready to use.
3. 6 commands for daily use
1. import data
ingest research-paper.pdf
Claude automatically reads the material and generates multiple interconnected knowledge pages.
Import multiple copies at once:
ingest all of these
2. query the knowledge base
what do you know about X?
Claude will search your knowledge base and quote relevant pages.
3. Save the current conversation
/save
Turn current conversations into permanent notes.
4. automatic study
/autoresearch prediction markets 2026
Automatically complete search, analysis, sorting, and archiving.
5. Clean up the knowledge base
lint the wiki
Check:
- Isolated notes
- error links
- Outdated content
- missing reference
4. Use MCP to let Claude directly operate notes
Instead of copying and pasting, let Claude read Obsidian directly:
claude mcp add-json obsidian-vault '{"type":"stdio","command":"npx","args":["-y","@bitbonsai/mcpvault@latest","/path/to/your/vault"]}' --scope user
Replace:
/path/to/your/vault
Is the path to your Obsidian folder.
Claude can then directly manage your knowledge base.
5. Let all projects share one "brain"
What's really powerful:
Your programming, writing, research, and learning can all call on the same knowledge base.
Add to the project CLAUDE.md:
## Wiki Knowledge Base
Path: ~/path/to/vault
When you need context:
1. Read wiki/hot.md first
2. Read wiki/index.md if needed
3. Then check specific pages
Later:
Read it once and reuse it everywhere.
6. Superpose Obsidian official Skills
Installation:
/plugin marketplace add kepano/obsidian-skills
/plugin install obsidian@obsidian-skills
Make Claude output more consistent with Obsidian format:
- Wikilink
- Callout
- database view
rather than ordinary text.
What should I do if I already have an Obsidian library?
No need to start over.
Put:
WIKI.md
Put it in your root directory.
Then ask Claude:
- Check Obsidian
- Check API plug-ins
- Configure MCP
- Ask:
"What is this library used for?"
Then automatically build the Wiki structure.
5 tips to keep your knowledge base growing
- Manage with PARA Method:
Projects
Areas
Resources
Archives
- Install Obsidian Web Clipper and save the web content directly in it.
- Weekly runs:
lint the wiki
Check for knowledge conflicts and missing links.
- Open Obsidian Git to automatically save historical versions.
- Use when encountering important decisions:
/think
Ask Claude to analyze the problem based on your knowledge base.
How will it grow?
Day 1:
There are 5 seed pages and a small map.
Week 2:
Dozens of materials entered, and knowledge began to connect with each other.
Month 2:
Instead of repeatedly searching for content you've seen in the past, you ask directly about your knowledge base.
Finally:
Your knowledge is no longer just a collection, but becomes a growing asset.
Pure Markdown.
The data belongs to you.
No subscriptions.
There is no lock.
Your second brain really starts working.
