Overview

What it is

CastReader reads any webpage aloud with paragraph highlighting that follows along as you listen. It strips away nav bars, ads, and sidebars — so you hear the article, not the clutter. Works on 15+ platforms including Kindle Cloud Reader, WeRead, Notion, and Google Docs. Free to use, no account needed.

Intent

I need it when

Proofread documents and catch errors by hearing text read aloud in natural-sounding voices

CastReader reads Google Docs, Gmail, Notion, and other documents with Kokoro AI voices that sound significantly more natural than browser built-in TTS, enabling users to catch typos and phrasing issues their eyes might miss during visual proofreading.

Listen to long AI chatbot responses without copying or selecting text while performing other tasks

CastReader adds a play button next to each AI response on ChatGPT, Claude, Gemini, DeepSeek, and other platforms, allowing users to listen to individual answers without interrupting workflow or manually selecting text.

Improve reading comprehension and reduce fatigue through dual-channel learning with synchronized audio and visual highlighting

CastReader provides real-time paragraph-level highlighting that auto-scrolls as content plays, helping users with dyslexia, ADHD, visual impairment, or reading fatigue stay focused and absorb material more effectively without screen strain.

Access Kindle Cloud Reader and WeChat Reading books as continuous audiobooks with automatic page-turning

CastReader is the only Chrome extension that reads Kindle Cloud Reader aloud using OCR to extract text from image-rendered pages, and handles WeChat Reading's Canvas-rendered content. It auto-advances chapters and can send audio to phones via Telegram for on-the-go listening.

Convert long-form web content into audio to consume while multitasking during commutes, exercise, or household chores

CastReader reads any webpage aloud with natural AI voices and paragraph-level highlighting, allowing users to listen to articles, Kindle books, PDFs, and AI responses while maintaining focus through synchronized text tracking. Supports 40+ languages and adjustable playback speed (0.5x to 2x).
