Podcastify

Podcastify is a browser extension for Chrome that reframes the way you consume written web content. Instead of reading an article, report or news story, you click the extension icon and it produces a podcast-style script from the page you are on, then reads it back in a natural-sounding synthetic voice. The whole loop happens inside the browser, so there is no separate app to open and no copy-pasting required.

The extension leans on OpenAI's text-to-speech models for narration, and you supply your own OpenAI API key through a built-in options page. Because the key is stored locally and only used by the extension, you keep control of your own usage and billing with OpenAI. Playback controls in the popup let you play, pause, stop and change the volume, and you can switch between different voices or script lengths.

It is aimed at people who learn better by listening: commuters, gym-goers, researchers skimming long documents and anyone who wants to multitask while getting through reading material. As a small, self-hosted-key utility rather than a full podcast production suite, it stays simple and cheap.
