Common questions
How is this better than just asking ChatGPT what Belsky would say?
Structured atoms with typed connections and confidence scores produce fundamentally different output than an LLM guessing from training data. You get specific frameworks, cited sources, intellectual evolution over time, and cross-brain synthesis. It's the difference between asking someone who read the Wikipedia summary and someone who has the entire corpus indexed.
I can build this myself.
You can — but will you? And will it be as good? The curation, connection typing, confidence scoring, voice extraction, and skill design are months of work. We've already done it. Your time is worth more than $29.
Context windows are getting huge. Why not just paste the raw content?
Connections, evolution tracking, and skills are the value — not pre-chunking. A 2M token window full of raw newsletters still won't give you /debate, /evolve, or /predict.
Will this always be free?
All brains are free right now. We'll add premium features later, but the core brain packs will always be accessible.
Can I use this commercially?
Standard and Pro tiers include personal and commercial use. API tier is for building products on top of the brain data. All brains use fair use of public content with full attribution.
