Readbox

Readbox offers an innovative service that converts emails into podcast episodes, providing an effortless method to experience long-form content from sources such as Substack as audio. Just forward emails to your personal Feed Email address, and Readbox will process the material, voice it over with advanced AI narration, and deliver it to an RSS feed compatible with popular podcast apps. This setup lets you hear newsletters and similar material while moving around, helping you remain updated and engaged without needing to stare at a screen.

Readbox assists content creators by simplifying the process of exposing their material to broader listeners. With rising interest in audio formats, it delivers a streamlined option for publishers struggling to produce and share podcast versions of their output. All converted items include proper attribution to the original authors, guaranteeing they get recognition. Personal feeds stay private and protected, viewable solely by the owner, which builds confidence in the platform's security.

Leveraging open standards, the RSS-based feeds integrate with leading podcast apps including Apple Podcasts, Google Podcasts, Overcast, and Pocket Casts. Spotify support is on the horizon, but for now, you can access your episodes straight from the Readbox site. Developed by Jacob Peddicord, Readbox remains free during its early access phase, appealing to those seeking to streamline how they ingest content.
