Convert newsletters into AI podcasts with GPT-4o Mini and ElevenLabs

🎧 Convert Unread Newsletters into Conversational AI Podcasts

Turn email overload into audio insights — automatically.

This workflow transforms unread newsletters sitting in your inbox into engaging, human-like audio conversations between two AI voices. It’s perfect for listening during your commute, workout, or while multitasking.

Inspired by Google's NotebookLM, this automation brings long-form content to life by summarizing dense text into a natural dialogue using OpenAI and generating high-quality voice narration with ElevenLabs. The result? A dynamic audio file sent right back to your inbox — hands-free, screen-free, and stress-free.
