+ai.log is part of the ai ecosystem - a static site generator that creates blogs with built-in AI features for content enhancement and atproto integration. The system follows the yui system principles with dual-layer MCP architecture.
+
+## Architecture
+
+### Dual MCP Integration
+
+**ai.log MCP Server (API Layer)**
+- **Role**: Independent blog API
+- **Port**: 8002
+- **Location**: `./src/mcp/`
+- **Function**: Core blog generation and management
+
+**ai.gpt Integration (Server Layer)**
+- **Role**: AI integration gateway
+- **Port**: 8001 (within ai.gpt)
+- **Location**: `../src/aigpt/mcp_server.py`
+- **Function**: AI memory system + HTTP proxy to ai.log
+
+### Data Flow
+```
+Claude Code → ai.gpt (Server/AI) → ai.log (API/Blog) → Static Site
+              ↑                      ↑

+### Supported Languages
+
+| Language | Code | Direction | Model Optimized |
+|----------|------|-----------|-----------------|
+| English  | `en` | ↔️        | ✅ qwen2.5      |
+| Japanese | `ja` | ↔️        | ✅ qwen2.5      |
+| Chinese  | `zh` | ↔️        | ✅ qwen2.5      |
+| Korean   | `ko` | ↔️        | ⚠️ Basic       |
+| Spanish  | `es` | ↔️        | ⚠️ Basic       |
+
+### Translation Workflow
+
+1. **Parse Document**: Analyze markdown structure and identify sections
+2. **Preserve Code**: Isolate code blocks and technical content
+3. **Translate Content**: Process text sections with Ollama AI
+4. **Reconstruct**: Rebuild document maintaining original formatting
+5. **Validate**: Ensure structural integrity and completeness
+
+### Integration with ai.gpt
+
+```python
+# Via ai.gpt MCP tools
+await log_translate_document(
+    input_file="README.ja.md",
+    target_lang="en",
+    model="qwen2.5:latest"
+)
+```
+
+### Requirements
+
+- **Ollama**: Install and run Ollama locally
+- **Models**: Download supported models (qwen2.5:latest recommended)
+- **Memory**: Sufficient RAM for model inference
+- **Network**: For initial model download only
+
+## Configuration Examples
+
+### Basic Blog Config
+```toml
+[blog]
+title = "My AI Blog"
+description = "Personal thoughts and AI insights"
+base_url = "https://myblog.example.com"
+
+[ai]
+provider = "openai"
+model = "gpt-4"
+translation = true
+```
+
+### Advanced Integration
+```json
+// ../config.json (ai.gpt)
+{
+  "mcp": {
+    "servers": {
+      "ai_gpt": {
+        "endpoints": {
+          "log_ai_content": "/log_ai_content",
+          "log_create_post": "/log_create_post"
+        }
+      }
+    }
+  }
+}
+```
+
+## Troubleshooting
+
+### MCP Connection Issues
+- Ensure ai.log server is running: `cargo run -- mcp --port 8002`
+- Check ai.gpt config includes log endpoints
+- Verify `./log/` directory exists relative to ai.gpt
+
+### Build Failures
+- Check Rust version: `rustc --version`
+- Update dependencies: `cargo update`
+- Clear cache: `cargo clean`
+
+### AI Integration Problems
+- Verify ai.gpt memory system is initialized
+- Check AI provider configuration
+- Ensure sufficient context in memory system
