+## 🧠 Now with LLM-powered excuses! (Optional)
+
+If you enable LLM support and provide an [OpenRouter](https://openrouter.ai/) API key, the excuses will be generated by an AI model for maximum hilarity.
+
+### 🎯 Thematic Excuses
+
+When using the LLM excuses, you can pass an optional theme to get a context-aware excuse:
+
+```http
+GET /no?theme=starwars
+```
+
+Example response:
+
+```json
+{
+  "reason": "I can't join yout Lightsaber duel club today; I left my lightsaber charging in the Death Star's cathode ray tube overnight and it's still stuck in hyperspace",
+  "theme": "starwars",
+  "source": "llm"
+}
