Two ways to get Claude inside Obsidian.
Plugin route.
Claude Code route.
Most articles dodge the question.
I'm not going to.
Why This Choice Matters More Than You Think
Pick the wrong route and you'll waste weeks fighting your tools.
Pick the right one and you'll have a second brain running in an afternoon.
I've run both for months.
Here's the straight answer.
The Plugin Route: Claudian And Smart Connections
The plugin route is the easy start.
You open Obsidian.
You go to the plugin store.
You search "Claudian" or "Smart Connections".
Install, add your API key, done.
Now you can chat with Claude inside your notes.
What The Plugin Route Is Good For
Quick questions about a single note.
Rewriting a paragraph.
Summarising the note you're looking at.
Chat-style back and forth.
It feels like having ChatGPT stapled to your notes app.
Where The Plugin Route Breaks Down
Plugins can't touch multiple files at once properly.
They can't reorganise your vault.
They can't build you a content calendar from 200 notes.
They can be buggy.
Some get abandoned.
You're stuck waiting for the plugin developer to fix things.
The Claude Code Route: The Real Power Move
Claude Code runs in your terminal.
You install it with one command.
You point it at your Obsidian vault folder.
Now Claude can read every file, write new files, run commands, move stuff around.
This is the one I use for real work.
What Claude Code Is Good For
Reorganising 500 notes.
Finding every note about a topic and writing a master summary.
Building a content calendar from all your ideas.
Watching a folder and automatically processing new notes.
Building knowledge agents.
Generating content in your voice from research.
Basically anything big.
Where Claude Code Is Harder
You need to get comfortable with the terminal.
That's the whole learning curve.
Five commands.
Takes a morning.
Never looked back.

Head To Head: The Real Comparison
Speed To Start
Plugin wins.
Ten minutes.
Click install, paste API key, go.
Claude Code takes about an hour the first time.
Power
Claude Code destroys the plugin route.
Not even close.
Plugins chat.
Claude Code does the actual work.
Reliability
Claude Code wins.
Plugins depend on third-party devs.
Claude Code is official Anthropic software.
Cost
Both need a Claude API key or subscription.
Same cost.
Learning Curve
Plugin is easier.
Claude Code has maybe five commands you'll use 95% of the time.
Not scary once you start.
My Actual Recommendation
Start with Claude Code.
Skip the plugin.
Here's why.
The plugin feels easier for the first day.
Then you hit the ceiling.
You want to reorganise your vault.
Plugin can't do it.
You want to generate 10 YouTube scripts from your notes.
Plugin can't do it.
You end up installing Claude Code anyway.
Just start there.
Save yourself the detour.
The Exact Claude Code Setup
Step 1: Install Claude Code
One command in your terminal.
Done.
Step 2: Make Your Vault
Open Obsidian.
Make a vault called "business brain" or whatever.
Step 3: Point Claude Code At The Vault
Open your terminal.
Navigate to the vault folder.
Run Claude Code.
That's it.
Step 4: Ask For Something Big
"Read every note in this folder. Find the ones about marketing. Make a new note called master marketing plan. Put all the best ideas in there. Organise them by traffic, leads, and sales."
Claude Code reads every file.
Picks the good stuff.
Writes a new note.
Organised.
Whole day of work.
One minute.
What I'd Use Each For
Real world call.
Plugin route: if you just want an AI chatbot living inside your notes and you never want to touch a terminal.
Claude Code: if you want AI that actually does the work for you.
90% of people reading this want option two.

Every single one.
