Narro was a service I operated from 2014-2023 and a company I operated from 2016-2023 that turned your reading list or blog into a podcast. It was the best way to listen to the internet. As one user said: "Pretty much the best thing to happen to your morning commute since the iPod."
For readers and consumers, it provided a way to send articles, ebooks, PDFs, videos, and plain text to a single source and have them transcribed via text-to-speech into a personal podcast.
For publishers, it provided a way to programmatically turn a blog or other feed into a brandable podcast for their audience. Public podcasts also came with audience engagement and demographic metrics.
