Hey HN,
I'm 18, built this solo over 7 months in India. Launched on Product Hunt this morning but wanted to share here for technical feedback.
What it is:
Nex Sovereign is a cognitive OS with 9 apps that make AI transparent:
Mind App – See its beliefs, values, goals + real-time dopamine/cortisol levels
Memory Graph – Auditable knowledge graph (not hidden RAG)
PDAR Thinking – Watch reasoning process (Perceive → Decide → Act → Reflect)
Boardroom – Internal CEO/CTO sub-agents make recommendations, you mandate approval (governance layer)
Chat, Memories, Goals, Settings
Tech stack:
Python/FastAPI (async event loop for cognitive simulation) + Next.js 14 + SQLite (local-first)
Why I built it:
Every AI is a black box. You never see what it believes, how it thinks, or why it decided. I wanted to solve interpretability at the architecture level (not as a research problem, but as a product design problem).
Current status:
Invite-only beta (8 concurrent users). Already got integration interest from Giselle (workflow orchestration platform).
Looking for feedback on:
Is the cognitive transparency useful or just "neat"?
Which app is most compelling? (Mind, Memory Graph, PDAR, Boardroom)
What would you build on a Nex SDK?

Happy to answer technical questions about the architecture.
