Welcome to Brain
Your personalized knowledge graph and recommendation system
Technology in Service of Consciousness
A conscious recommendation system optimizing for learning and growth, not engagement. Build your personal knowledge graph across 12 different domains of human knowledge.
How it works
React to just a few entities—books, concepts, people, or works of art. Brain will learn your intellectual profile and recommend connections you'd never discover on your own. The more you engage, the smarter your recommendations become.
Explore 12 Types of Cultural Entities
What if algorithms helped you grow instead of keeping you engaged?
Semantic Discovery
Using 384-dimensional vector embeddings, Brain understands deep connections between entities. Discover how Nietzsche relates to film noir, or how Japanese aesthetics resonate with minimalist music.
Cross-Domain Learning
Break knowledge silos. When you react to a book, Brain might suggest films with similar themes, philosophical concepts, mathematical patterns, or music expressing the same emotional truth.
Your Intellectual Journal
Every reaction builds a living record of your intellectual journey. Track your evolution, observe how your interests develop, and build invaluable intellectual capital over time.
Conscious Consumption
No infinite feeds. No engagement optimization. Optional "productive friction" mechanisms encourage reflection before consumption. Every interaction is mindful and deliberate.
Nuanced Reactions
Beyond simple likes: 🧠 Mind (intellectually stimulating), ❤️ Heart (emotionally resonant), 🔥 Fire (inspiring), 🧩 Puzzle (thought-provoking), 🕳️ Void (not for you).
Cathedral Thinking
Built for the long term. Not for viral growth or engagement metrics, but for the person who wants to spend the next decade becoming genuinely wiser.
Tired of Technology That Exploits Your Attention?
Every major platform you use employs algorithms engineered to keep you scrolling, watching, clicking—not because it serves your growth, but because engagement generates revenue. Brain is different.
We reject the attention economy. We choose human growth over corporate growth. We build technology that serves consciousness instead of exploiting it.
