Mail Jockey

Newsletter Radio Jockey is a Chrome extension that converts daily email newsletters into an interactive, voice-driven audio experience. Many users receive valuable newsletters but rarely read them due to time constraints or information overload. This project solves that problem by automatically fetching today’s newsletters from Gmail, summarizing and cleaning the content, and transforming them into a dramatic radio-host–style audio experience powered by ElevenLabs. A floating button appears on every webpage, allowing users to instantly listen to their newsletters and engage in conversational follow-ups. The entire flow—from Google authentication to Gmail retrieval, text processing, TTS generation, and audio playback—runs end-to-end inside the browser with no manual setup.

When the user logs in through Google OAuth, the extension retrieves today’s newsletter emails, extracts the sender, subject line, and readable body content, and pipes the combined text to ElevenLabs for expressive voice synthesis. The result is played through a sliding drawer UI injected into the browser. This setup demonstrates an autonomous agent handling multi-step tasks across cloud APIs, browser capabilities, and voice interaction.
