Obsidian + AI
Analyze Your Obsidian Vault
How to analyze your Obsidian vault with AI
You can analyze your Obsidian vault with Rodin by exporting your notes as markdown and pasting them in. Rodin's AI reads across your entire body of writing to find patterns you might not see yourself: recurring themes, mental models you rely on, questions you keep circling, and blind spots in your thinking.
What Rodin extracts from your vault
Recurring themes
What you keep returning to across months and years of notes — the subjects that surface again and again regardless of what you thought you were writing about.
Open questions
The problems you keep circling without resolving. A vault is full of questions that never quite close — Rodin names them.
Mental models
The frameworks you reach for when reasoning through new problems. Often borrowed from one domain and quietly applied to others.
Intellectual DNA
Who shaped your thinking — the authors, thinkers, and traditions whose frameworks live in your prose, even when you have stopped citing them.
Blind spots
What your writing systematically avoids. The counterarguments not made, the disciplines not consulted, the assumptions never examined.
Core question
The single driving question behind all your writing — often one you have never stated explicitly but that has organized years of thinking.
One-liner
Your intellectual project in a sentence. What you are actually working on, underneath all the varied topics.
Archetype
A three-word identity that captures how you think — for example, "The Contrarian Synthesiser" or "The Systems Poet." Compressed enough to be memorable, specific enough to mean something.
Step-by-step: Obsidian to Rodin
Open your vault folder
Open your Obsidian vault folder on your computer. You will find a collection of .md files — one per note.
Select your notes
Select the notes you want analyzed, or use all of them for the most accurate fingerprint. More text means more signal.
Upload to Rodin
Copy the text content and paste into Rodin — or use the file upload to drag your .md files directly into the upload area. Rodin parses wikilinks and extracts knowledge graph structure as additional context.
Wait while the AI reads
Wait about 30 seconds as the AI reads across your writing and extracts patterns. The fingerprint streams back in layers as it is generated.
Review your fingerprint
Read your 8-layer intellectual fingerprint. Most people find the core question and blind spots the most surprising — the things they knew but had never seen written down.
Create your public profile
Add your name and a contact handle. Your profile goes live at rodin.fyi/p/[id] — a shareable link with an OG image card and a list of similar thinkers.
Why a vault is better than a single essay
Obsidian vaults contain years of thinking. A single essay shows what you thought on one topic on one day. A vault shows the patterns: what you keep returning to, how your thinking evolves, where your mental models repeat across domains.
More text means a more accurate fingerprint. A vault of 500 notes will reveal things a single essay never could — not because any single note is more profound, but because the pattern only becomes visible at scale.
Beyond Obsidian
Rodin works with any writing. Export your Notion workspace as markdown. Use a Logseq, Roam, or Bear export. Paste from Apple Notes. Drop in plain text files. The tool does not require a particular format — it requires volume and authenticity.
The key is that the writing is yours: notes you took for yourself, not polished for an audience. Personal writing reveals how you actually think, not how you want to be perceived.
Cognitive Topology Analysis
Beyond the 8-layer fingerprint, Rodin runs a 12-dimensional Cognitive Topology Analysis — a proprietary engine that measures how you structure thought. It extracts dimensions including epistemic confidence, temporal orientation, argument density, abstraction level, conceptual leap distance, and dialectical complexity.
This captures whether you reason from authority or first principles, whether you think in systems or narratives, whether your arguments build linearly or spiral. It is what makes Rodin's matching engine different: it compares not what two people think about, but how they structure thought.
Common questions
- How many notes do I need?
- At least a few thousand words, but more is better. A vault of 50 notes will produce a fingerprint. A vault of 500 notes will produce a more accurate one. Rodin looks for patterns across your writing — the more writing, the clearer the pattern.
- Does Rodin store my vault?
- A portion of your writing is stored to support your profile and enable fingerprint evolution over time. Your writing is not used to train AI models. You can delete your profile and all associated data at any time.
- Can I update my fingerprint with new notes?
- Yes. Rodin supports evolving fingerprints that track how your thinking changes over time. You can submit new writing to update your fingerprint and see how your themes, questions, and mental models have shifted.
Your vault already contains your intellectual fingerprint. Rodin surfaces it.
