| Description | Read Aloud is a free browser extension for Chrome, Firefox, and Edge that reads the content of any web page aloud with a single click. It's aimed at students and everyday readers who want zero-friction, no-cost narration, and it stands out from other TTS extensions by letting power users plug in premium voices from Google WaveNet, Amazon Polly, IBM Watson, Azure, and OpenAI via their own API keys. Out of the box it uses the browser's built-in system voices and supports 40+ languages. | CastReader is a text-to-speech reader available as browser extensions and mobile and desktop apps. It reads webpages, PDFs, Kindle books and AI chatbot answers aloud with synced highlighting. |
