I use Claude every day. For months, I lost everything between sessions. Then I found two tools that changed it.

I. The problem
Every session started from zero.
I work with Claude for hours every day — brand work, worldbuilding, scripts, video prompts, business strategy. Every morning I'd open a new chat and have to re-explain everything: who I am, what I'm building, what I decided yesterday, what we were in the middle of.
Some days I'd give up and start something new just because re-orienting Claude felt heavier than the actual work.
It wasn't Claude's fault. It was that I had no system — no place that lived outside the chat window for both of us to look at. My notes were in five apps. My decisions were in screenshots. My memory was in my own tired head.
Sessions ended and everything we made dissolved.
II. The stack
Three pieces, one nervous system.
The shift was small in terms of tools and enormous in terms of what it unlocked. I added two things to Claude. That's it.
i.
Obsidian
A folder of markdown files on my Mac. I write everything in here — projects, decisions, lessons learned, conversations with myself. Claude can read it. Claude can write to it. The folder is the brain that doesn't forget.
ii.
Graphify
The connective tissue. It scans my whole vault and builds a knowledge graph — nodes, edges, communities, the surprising links between things I didn't see myself. Then it serves the graph to Claude instead of the raw files.
iii.
Claude
Connects to the folder. Reads the graph before answering. Writes back to the folder when we decide something new. Across sessions, across projects, across moods. Claude with memory finally feels like a partner, not a stranger.
The order matters. Obsidian without Claude is a folder of notes you never re-read. Claude without Obsidian is a brilliant stranger who forgets your name. Add Graphify and the whole thing starts thinking with you instead of behind you.
III. Inside Obsidian
A folder that becomes your memory.
Obsidian is a free app for writing notes in plain markdown. You pick a folder on your computer, point Obsidian at it, and that folder is now your vault. Every note you write is a small .md file sitting on your disk — no cloud lock-in, no proprietary format, no subscription. Open the folder in Finder and it's just files. That's the whole point.
What it actually does for you. You write a note. You link to another note with [[double brackets]]. Suddenly your notes know each other — backlinks form automatically, the graph view shows you what connects to what, and search runs across everything you've ever written in milliseconds. It's the only system I've used where the more I write, the smarter it gets.
Why it matters for Claude. Claude can read and write to the same folder. So when I tell Claude something today — a decision, a brand rule, a creative beat — it goes into a note. Tomorrow's Claude reads that note and already knows. The vault becomes the shared memory between every session. No more re-explaining.
Your vault, aliveEvery note a small markdown file. Every link a backlink. The more you write, the more the system connects on its own.
Three things you can do, day one.
a/Write a note about what you're working on today. Title it. Save it. That note now exists in plain text on your disk, forever.
b/Type [[ and start linking notes together. Mention an idea, project, or person. Obsidian auto-suggests existing notes and creates the backlink instantly.
c/Point Claude at the same folder. Now Claude reads your notes when answering, and can save new notes when you decide things together. The vault becomes shared memory.
IV. Inside Graphify
A brain that wakes up.
Graphify is an open-source skill that reads every file in your folder — markdown notes, PDFs, code, images, even video transcripts — and builds a queryable knowledge graph from what it finds. The graph captures the people, ideas, places, and decisions inside your work, and the edges between them. It runs locally. Your content never leaves your machine.
Why it matters. A 100-file vault might be 200,000 tokens raw. Graphify compresses that into a few thousand tokens of structured signal Claude can navigate in milliseconds. Up to 71.5× fewer tokens per session. Faster, cheaper, and Claude actually finds the threads you'd lost track of yourself.
What you get. A folder called graphify-out/ next to your vault, containing a graph report, a navigable HTML graph viewer, and a JSON file Claude reads automatically. Open the HTML in your browser and you can walk the connections yourself. They're often surprising.
Live previewYour notes, animated as a knowledge graph. The real one Graphify generates is queryable, navigable, and yours alone.
Using it in three moves.
a/Point it at a folder. Run graphify ./vault --obsidian and walk away. Ten minutes later you have a graph.
b/Tell Claude where it is. One line in CLAUDE.md: "Before answering, read graphify-out/GRAPH_REPORT.md." Claude will check the graph first, always.
c/Re-run when you've written a lot. Add new notes, run the same command, the graph refreshes. Your brain grows with you.
V. Together
Where the two meet.
Obsidian alone is a great notes app. Graphify alone is a graph tool. The reason this works is what happens when you put them in the same folder.
Obsidian gives Graphify clean material. Because everything you write is plain markdown — with [[backlinks]] already in the text as semantic signal — Graphify gets a structured corpus to graph, not a pile of random files. The links you draw by hand become the scaffolding the graph builds on top of.
Graphify amplifies what Obsidian sees. Obsidian shows you the links you made. Graphify shows you the links you didn't make — communities of ideas the AI detected across your vault, surprising semantic neighbours you'd forgotten you wrote about, clusters that suggest a project you didn't realise was forming. Your manual links + the inferred ones = a much richer map.
Both together serve Claude. The vault is the source of truth (your actual notes). The graph is the compressed index Claude reads first. Claude answers from the index, writes new notes back to the vault, and the next graph re-build folds those new notes in. The loop closes. Each piece makes the other two better.
The handshakeObsidian writes. Graphify connects. Claude reads, answers, and writes back. The loop closes.
VI. A day in the system
What it actually feels like.
A normal Monday in my studio. Three concurrent projects, two clients waiting, one creative thread I want to keep alive in the background.
9:00 — morning open
I greet Claude. It reads my "Tomorrow" handover note from last night and knows exactly where we left off. No re-explaining.
11:00 — context switch
A client asks about a project we last touched two weeks ago. Claude pulls the relevant decisions from the graph in seconds. No screenshots, no scrolling, no "remember when we talked about…"
14:00 — connection I didn't see
Graphify surfaces a link in the report — a brand thread I'd been working on connects to a workflow lesson I'd written three weeks earlier. The graph saw it. I hadn't.
17:00 — wrap
We write a "Tomorrow" note together. Claude saves it to the vault. Tomorrow's Claude will read it first thing. The thread never drops.
It sounds small written out. Living in it changes how you trust the tool. Claude went from assistant I talk at to partner I plan with.
VII. How to start
10 minutes to your own setup.
None of this requires being a developer. If you can copy a command and click an install button, you have everything you need.
1
Install Obsidian and create your vault
Download Obsidian from obsidian.md. It's free and runs on Mac, Windows, and Linux.
Pick a folder anywhere on your computer — ~/Documents, ~/Obsidian, your iCloud Drive, anywhere you'd back up. Name the folder anything you want. Mine is Spectralmoon OS. This folder is now your vault.
Open Obsidian → "Open folder as vault" → select the folder. Done. Create your first note with Cmd/Ctrl + N. Type [[ and you can link it to any other note as you write.
2
Install Graphify
Open Terminal and paste this. Graphify is an open-source Python tool that turns your folder into a queryable knowledge graph.
uv tool install graphifyy && graphify install
Don't have uv? Use pipx install graphifyy && graphify install instead.
In Claude Desktop, point Claude at your Obsidian vault folder using a connector — Claude can now read and write your notes. If you're using Claude Code, run this from inside your vault:
graphify claude install
This writes a section to your CLAUDE.md telling Claude to read the graph report before answering, and installs a hook that fires before every file lookup. Up to 71.5× fewer tokens per session when the graph is wired in.
From there, the magic comes from writing. Start small — one note for what you're working on today. A "Tomorrow" handover note before you stop. A decision log when something feels worth remembering. Don't try to organize everything upfront. The graph will find the connections.
