Por qué elegir CastReader en lugar de TTSReader

Simple online text-to-speech tool and Chrome extension? Esto es lo que CastReader hace diferente.

AI Voices

Sounds Like a Human, Not a Robot

TTSReader uses your browser's built-in speech synthesis — the same voices as Siri or Google Assistant. CastReader uses Kokoro AI voices trained specifically for reading. The difference in naturalness, pacing, and emphasis is dramatic.

Paragraph Highlighting

See Where You Are

TTSReader plays audio without visual tracking. CastReader highlights each paragraph on the actual page, auto-scrolls, and lets you click to jump. Essential for focus and comprehension.

Works Everywhere

Kindle, ChatGPT, and More

TTSReader works on simple webpages. CastReader has 15+ specialized extractors for Kindle, WeRead, ChatGPT, Claude, Gemini, Notion, Medium, Google Docs, and more. One extension for everything.
