Is the Chrome Extension free?

Yes — completely free with no limits! CastReader is 100% free to use: no login required, no monthly caps, no premium tier. It supports 40+ languages with natural AI voices. Install and listen to as much as you want, forever.

Does it work on any website?

Yes — it works on virtually any webpage with text content. Articles, blogs, documentation, news sites, you name it. For complex platforms like Kindle Cloud Reader and WeRead, we built deep integrations that understand their rendering engines. For everything else, our universal extractor handles it automatically.

How does it handle Kindle's DRM content?

CastReader reads the visually rendered text on your screen — the same content you see in your browser. It doesn't bypass any DRM or download book files. Think of it like a screen reader, but with natural AI voices.

Does it support languages other than English?

Yes! CastReader supports 40+ languages including Chinese, Japanese, Korean, Spanish, French, German, and many more. The AI voices handle multilingual content naturally, including mixed-language paragraphs.

Will it slow down my browser?

No. The extension only activates when you click the icon. It runs entirely in the browser tab with minimal resource usage. Audio is generated via API and streamed efficiently.

Does it work on Firefox or Safari?

Yes! CastReader is available for Chrome, Edge, Firefox, and other Chromium-based browsers (Brave, Arc, etc.). Safari support is planned for a future release.

CastReader processes text on the page you're viewing and sends it to our AI voice API — that's it. We don't store your browsing history, page content, or any personal data.
