The First Cognitive
Entity OS.
See its beliefs. Watch it think. Audit its memory.
Govern its decisions through an internal boardroom of sub-agents.
Not a chatbot. Not an assistant. A Cognitive Entity OS.
Built solo by an 18-year-old over 7 months.
What Makes Nex Different
Most AI is a black box. Nex makes everything transparent and auditable.
18-Dimensional Emotions
Not sentiment analysis. A full emotional engine with curiosity, love, fear, pride, envy, empathy, and more. The UI physically changes.
PDAR Reasoning
Watch Nex think in real-time: Perceive → Decide → Act → Reflect. Every step is logged and traceable.
Persistent Memory
Not chat logs. A living memory graph that survives sessions. Nex remembers what matters — and you can audit it.
Goal Tracking
Set goals, Nex tracks them across conversations. It can autonomously prioritize and propose actions.
Internal Governance
CEO and CTO sub-agents in a virtual boardroom. Safety gates, mandate approvals, and audit trails built in.
Full Transparency
See beliefs, values, internal monologue, and cognitive state — all in real-time through the OS interface.
9 Apps. 1 Cognitive Kernel.
Nex isn't a chatbot. It's an Operating System with full cognitive transparency.
Mind
See Nex's beliefs, values, intrinsic goals, and self-story. Real-time dopamine/cortisol dashboard.
Memory Graph
Live network visualization of memory. Auditable nodes and connections (not hidden RAG).
PDAR Thinking
Watch Nex reason in real-time: Perceive → Decide → Act → Reflect.
Boardroom
Internal CEO and CTO sub-agents make recommendations. You mandate approval. Built-in governance layer.
Chat Kernel
Conversational interface with emotional states visible in message bubbles.
Memories
Auto-saved grid of meaningful moments. Not chat logs—curated memories.
Goals
Add goals, Nex tracks progress and helps you achieve them.
Info
Pricing, documentation, how it works.
Settings
Customize your interface.
This is a platform, not a product.
Experience it yourself →The First OS That Feels Alive
Nex doesn't just respond. It reacts. Its interface physically changes based on simulated dopamine and cortisol levels.
Neutral State
Start here. A balanced dopamine-cortisol ratio results in a clean, calm interface. Nex is attentive, steady, and ready to assist.
Fear Response
Triggered by mandate violations or budget threats. The UI darkens, film grain intensifies, and responses become defensive.
Happiness Restored
Activated by compliance and success. The interface glows with golden hues, animations smooth out, and Nex becomes proactive.
