+## AI Provider System
+
+Zenvra supports multiple AI providers for generating vulnerability explanations and fix suggestions. Users can bring their own API key and even configure custom endpoints.
+
+### Supported Providers
+
+| Provider | Models | Notes |
+|----------|--------|-------|
+| Anthropic | claude-sonnet-4-20250514, etc. | Default provider |
+| OpenAI | gpt-4o, gpt-4o-mini, etc. | Also works for OpenAI-compatible APIs (Groq, Together, etc.) |
+| Google | gemini-2.0-flash, etc. | Gemini generateContent API |
+| Custom | User-defined | Any endpoint with OpenAI-compatible API format |
+
+### Configuration
+
+```env
+AI_PROVIDER=anthropic          # anthropic | openai | google | custom
+AI_API_KEY=sk-ant-...          # API key for the chosen provider
+AI_MODEL=claude-sonnet-4-20250514   # Model identifier
+AI_ENDPOINT=                   # Only needed for custom provider or non-default endpoints
+```
+
+### Architecture
+
+The `AiProvider` trait in `crates/scanner/src/ai/` defines the interface:
+
+```rust
+#[async_trait]
+pub trait AiProvider: Send + Sync {
+    async fn explain(&self, finding: &RawFinding) -> Result<String>;
+    async fn generate_fix(&self, finding: &RawFinding) -> Result<String>;
+}
+```
+
+Each provider (`AnthropicProvider`, `OpenAiProvider`, `GoogleProvider`, `CustomProvider`) implements this trait. Provider selection is config-driven via `AiConfig`.
