# Ocho vs. Obsidian

> A beloved personal vault vs. a shared brain built from documents you already have.

Obsidian is one of the best personal knowledge tools ever made: local markdown files you own outright, linked notes, a famous graph view, and thousands of community plugins. If the app vanished tomorrow, your notes would still open in any text editor. For an individual thinker building a vault of their own writing, it's excellent — and its core app is free.

The catch is in that sentence: *a vault of their own writing.*

## What Obsidian does well

- **True data ownership.** Plain markdown on your disk; no lock-in, works

offline, private by default.

- **Flexibility.** Thousands of plugins and themes; power users build exactly

the workflow they want.

- **Longevity.** Your notes will be readable in 20 years regardless of what

happens to any vendor.

## Where it stops

- **You write everything.** Obsidian has no ingestion: no connectors for

SharePoint, Drive, Notion, or GitHub, no pipeline that reads your existing   PDFs and decks. The vault contains what you typed into it.

- **The graph maps your links, not your knowledge.** The graph view

visualizes `[[links]]` you created by hand — no entity extraction, no   inferred relationships. Past a couple hundred notes it's widely described   as beautiful but unnavigable.

- **Single-player.** No real-time collaboration, no roles or permissions, no

admin controls. Teams bolt on third-party sync tools; it stays a personal   tool shared awkwardly.

- **AI is a plugin, per person.** Community AI plugins (Copilot, Smart

Connections) chat over one personal vault, with limited source attribution   and cloud-privacy trade-offs. There's no shared, cited AI over an   organization's corpus.

## What Ocho does differently

- **Ingestion instead of authorship.** Connect the tools your company already

uses — or drag in files — and Ocho parses, indexes, and keeps syncing.   Nobody retypes the knowledge that already exists.

- **An extracted graph.** Ocho's [knowledge

graph](/docs/market-comparison/what-is-a-knowledge-graph) is built by AI   from document content — entities, relationships, confidence scores —   and it updates itself when documents change.

- **One brain, whole team.** Shared datasets, role-based permissions, and AI

chat where every answer cites the exact page — the same experience for   everyone, not a per-person vault.

- **A harness, not a plugin.** Cited chat, graph-connected search, retrieval

evaluations, and [Flows](/docs/flows/overview) automations ship as one   product.

## Which should you use?

Both, honestly. Obsidian is superb for your personal thinking — Karpathy's own [LLM-wiki setup](/docs/market-comparison/ocho-vs-karpathys-second-brain) uses it as a front-end. But the notes you write are a sliver of what your organization knows. For the thousands of documents nobody will ever hand-link — the contracts, specs, decks, and transcripts you already have — you want a brain that builds itself. That's Ocho.
