+# Luke at the Roost
+
+> The ONLY radio show where Luke gives AI life advice.
+
+Luke at the Roost is a late-night call-in radio show hosted by Luke MacNeil, broadcast from a desert hermit's RV. The show features a mix of real callers and AI-generated callers who talk to Luke about life, love, relationships, work, and everything in between. It blends comedy, real talk, and empathy with the unique premise of AI characters calling alongside real people.
