Open Brain FAQs

Question 1

What is Open Brain?

Accepted Answer

Open Brain is a self-hostable personal knowledge infrastructure tool that leverages AI-generated embeddings and a dynamic knowledge graph to help you capture, semantically search, and manage your thoughts by meaning, not just keywords.

Question 2

How does Open Brain facilitate semantic search?

Accepted Answer

It uses AI to generate vector embeddings for your thoughts, converting them into numerical representations of their meaning. This allows you to perform highly accurate semantic searches, finding relevant information even if the exact keywords aren't present.

Question 3

Can I capture thoughts from various sources?

Accepted Answer

Yes, Open Brain supports multiple ingestion pipelines. You can capture thoughts via a Telegram bot, automated RSS feeds, AI clients like Claude or ChatGPT using the Model Context Protocol (MCP), and other custom pipelines.

Question 4

What are the benefits of the dynamic knowledge graph?

Accepted Answer

The dynamic knowledge graph automatically links related thoughts, extracts entities (people, projects), and tracks co-occurrence patterns. It helps maintain context, synthesize insights, and provides a richer understanding of your captured knowledge.

Question 5

Is my data secure and private with Open Brain?

Accepted Answer

Absolutely. Open Brain is designed to be self-hostable with options like Supabase or Docker, ensuring that all your data resides in your own database. You maintain full ownership and control over your personal knowledge infrastructure.
