Obsidian vs. Make0 Brain: Aren't they basically the same thing? Not quite. 🧠

I keep seeing people draw parallels between Obsidian and Make0 Brain. And honestly, I get why.

Both store context. Both can connect to AI agents. Both can help AI work with information you've accumulated over time.

But there's a fundamental difference in how they approach memory.

📚 Obsidian is a knowledge vault.

Your notes live in Markdown files. You organize them, link them, build knowledge graphs, and can connect your vault to AI agents through plugins and community integrations.

It's a great system for capturing and organizing knowledge.

🧠 Make0 Brain is a memory layer for AI agents.

Instead of treating memory primarily as a collection of notes, Make0 manages reusable facts, preferences, people, projects, and decisions.

Memories can be added, updated, versioned, and deleted. A graph connects related information, while hybrid retrieval helps agents find relevant context when they need it.

And because the Brain connects through MCP, that memory can travel across compatible tools like ChatGPT, Claude, Cursor, and Codex.

The distinction isn't whether an AI can access your notes. It's how the information is structured, maintained, and retrieved as memory.

You can connect an agent to an Obsidian vault. But connecting an agent to a vault and giving it a dedicated, versioned memory system are two different approaches.

And you don't necessarily have to choose one.

Obsidian can remain the place where you develop ideas and maintain your knowledge base. Make0 Brain can manage the context you want your AI agents to carry across sessions and tools.

Different layers. Potentially complementary.

Now I'm curious:

1. If you're using Obsidian with AI agents, how do you currently handle memory updates, outdated facts, and conflicting information?

2. Would you prefer your AI memory to live inside your knowledge vault, or as a separate layer shared across AI tools?

3. Do you see dedicated AI memory systems as a distinct category, or do you think a well-connected knowledge base can solve the same problem?
