-## 💡 About NullAI
-
-NullAI uses a revolutionary **Knowledge Tile System** where each piece of information is:
-1. Stored as a verifiable "tile" in a multi-dimensional knowledge space
-2. Validated by domain experts with ORCID authentication
-3. Assigned spatial coordinates for semantic relationships
-4. Continuously monitored for accuracy and relevance
+**Note**: This is a demonstration interface. For full functionality, deploy the complete NullAI system.
 
-**This Demo:** Uses DeepSeek R1 (7B) with 8-bit quantization. Features are simulated to showcase the concept.
-
-**Production System:** Connects to real knowledge base with actual expert verification and spatial encoding.
+**Model**: [nullai-deepseek-r1-32b](https://huggingface.co/kofdai/nullai-deepseek-r1-32b)
+**Documentation**: See model card for comprehensive features

-    ## 🔬 Technical Architecture
+    ## 🔬 Key Features
 
-    NullAI combines multiple innovative components:
+    ### **Knowledge Tile System** (倒木システム)
+    Each piece of knowledge is a structured, self-contained unit with:
+    - Spatial coordinates (abstraction × expertise × temporality)
+    - Certainty scores
+    - Reasoning chains
+    - Expert verification (ORCID)
+    - Citations and evidence
 
-    1. **Knowledge Tile Generator**: Creates structured knowledge units from expert input
-    2. **Spatial Encoder**: Maps tiles to multi-dimensional semantic space using coordinate systems
-    3. **Judge System**:
-       - **Alpha Lobe**: Validates logical consistency and factual accuracy
-       - **Beta Lobe**: Checks for hallucinations and contradictions
-    4. **Inference Engine**: Retrieves and synthesizes relevant tiles for each query
-    5. **Confidence Calculator**: Provides transparent uncertainty quantification
+    ### **Multi-Stage Judge System** (ジャッジシステム)
+    Every answer verified through three tiers:
+    1. **Alpha Lobe**: Logical consistency
+    2. **Beta Basic**: Domain knowledge alignment
+    3. **Beta Advanced**: Deep reasoning validation
 
-    ### 🎓 Domain Specializations
+    ### **Database Isolation** (DB分離)
+    Separate databases for each domain prevent cross-contamination
 
-    Medical • Legal • Programming • Science • Economics • Engineering • Mathematics •
-    History • Literature • Philosophy • Psychology • Business • Education • Arts • Languages • and 40+ more!
+    ### **Create Specialized LLMs in Hours**
+    - Educational LLMs: Math, science, language learning
+    - Medical LLMs: Clinical decision support, diagnostics
+    - Legal LLMs: Contract analysis, compliance
+    - Enterprise LLMs: Custom knowledge bases
