CastReader is a Chrome and Edge browser extension that reads webpages, documents, and AI chat responses aloud. It combines text-to-speech with real-time highlighting and auto-scroll so users can follow along on the page while listening. The product also includes a Read & Explain mode that summarizes pages in the listener’s chosen language while marking key points on the original text. That makes it useful for long articles, foreign-language pages, research papers, ebooks, and chat-based reading workflows where hearing the content is easier than reading it directly. ## O que CastReader pode fazer? ### Read aloud with synced highlighting Reads webpages, docs, Kindle pages, and chats aloud with natural AI voices, real-time paragraph or word-level highlighting, and auto-scroll to keep the page in sync. ### Read & Explain mode Adds an Explain mode that summarizes and unpacks pages in your language while marking the key points on the original text with a moving pen. ### Broad page and app coverage Supports text-to-speech on articles, PDFs, Google Docs, Gmail, Notion, Feishu Docs, Yuque, WeRead, Kindle, ChatGPT, Claude, and more. ### Per-response listen buttons Lets you listen to individual AI responses on supported chat platforms, so you can hear one answer without replaying the whole conversation. ### Language and voice options Supports 40+ languages on the free experience and 100+ premium voices on Pro, with speeds up to 2× free and up to 3× on Pro. ### Pro listening extras Includes cross-device sync and MP3 export on Pro for users who want their listening progress and audio files available beyond one browser session. ## Casos de uso ### Read long web articles hands-free Open a long article, newsletter, or forum post and let CastReader read it aloud while the current paragraph highlights and the page auto-scrolls. ### Understand difficult or foreign text Use Read & Explain on dense or foreign-language pages to hear a plain-language explanation while key points are marked on the original page. ### Listen to ebooks in the browser Open Kindle, WeRead, or other supported reading pages in the browser and continue through chapter-style reading with auto-advance. ### Follow AI answers without re-reading Click the listen button on ChatGPT or other supported AI responses to hear a single answer instead of the whole conversation. ### Review documents and email by ear Use the document and email support in Google Docs, Gmail, Notion, Feishu Docs, or Yuque to proofread or review material by ear. ## Perguntas frequentes ### Is listening free?
