Once installed as a Chrome or Edge extension, or opened as an iPhone, iPad or Android app, it reads supported pages and documents aloud using natural AI voices while a word-synced highlight and auto-scroll keep your place. A public Voice Hub lets you preview real voice samples by language before committing, and playback speed ranges from standard rates up to 3x on the paid plan. What separates it from a plain screen reader is a feature called Read & Explain. Instead of only pronouncing a dense or foreign-language paragraph, CastReader works out what it means and walks you through it in the language you know best, while an animated pen circles and underlines the relevant lines in the original text. That mix of eyes-on-page and ears-on-explanation is aimed at research papers, technical documentation, foreign-language news and other long reads where passive narration is not enough. Sources are organised into four families: book platforms such as Kindle, WeRead, Google Play Books, Libby, Kobo and O'Reilly; articles and subscriptions including Medium, Substack, The Atlantic, The New Yorker and major newspapers; work documents and email such as Google Docs, Notion, Gmail and Google Drive; and AI conversations from ChatGPT, Claude, Gemini, DeepSeek and Kimi. CastReader also offers private voice cloning for your own documents and a developer Voice API for embedding cloned speech into applications. Free use needs no account, and payments are handled by Stripe. **Pricing & Plans:** Freemium.

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. **Pricing & Plans:** Free to install as a Chrome extension; you provide your own OpenAI API key, so text-to-speech usage is billed by OpenAI according to your account. The extension itself has no separate subscription. - **One-click page-to-podcast:** Generate a podcast-style script from whatever webpage you are viewing with a single click in the toolbar. - **OpenAI text-to-speech narration:** Uses the latest OpenAI TTS voices to read the script aloud in natural, human-sounding audio. - **Bring your own API key:** Enter your own OpenAI API key on a secure options page so the key stays under your control and is only used by the extension. - **In-popup playback controls:** Play, pause, stop and adjust volume from the popup, and switch between voices or script lengths. - **Hands-free learning:** Listen to articles, news and research while commuting, exercising or doing other tasks. **Strengths:** Simple one-click workflow inside the browser; Natural OpenAI voices and adjustable playback; You control cost by using your own API key; Hands-free listening for articles and news **Limitations:** Requires an OpenAI API key and separate OpenAI billing; Narration quality and length depend on the page content; Chrome-only and dependent on OpenAI availability [Profile (Markdown)](https://openaitools.app/tool/podcastify.md) ## Frequently Asked Questions ### How do CastReader and Podcastify compare in monthly traffic?
