Reads ChatGPT responses aloud — word-by-word highlighting follows along
How CastReader Works with ChatGPT
Smart extraction meets natural text-to-speech
New in 2026
🔊 Listen Button on Every ChatGPT Response
CastReader now adds a small Listen button next to every individual ChatGPT response. Click it to hear just that answer — not the entire conversation. The only Chrome extension that does this on every AI platform.
Smart Extraction
Extracts Chat Content, Not UI
CastReader's dedicated ChatGPT extractor identifies assistant messages and skips UI elements, navigation, and system text. Only the actual conversation gets read.
Highlighting
Follow Along as It Reads
Each paragraph highlights in real-time as it's read aloud. Auto-scroll keeps you in sync. Click any paragraph to jump there.
Natural Voices
40+ Languages, Natural AI Voices
Powered by the Kokoro TTS model. Not robotic — natural, expressive voices in 40+ languages.
Frequently Asked Questions
Everything you need to know about listening to ChatGPT with CastReader
Where does the Listen button appear on ChatGPT?
A small 🔊 Listen button appears next to every ChatGPT response automatically — no setup, no shortcuts. Click it and only that response is read aloud, not the rest of the conversation.
Does it read both user and assistant messages?
By default, CastReader reads assistant (ChatGPT) messages. The extractor filters out user prompts and system UI to focus on the actual content.
Does it work with GPT-4, GPT-4o, and other models?
Yes. CastReader extracts from the rendered page, so it works regardless of which model generated the response.
Is it free?
Completely free. No API key, no usage limits, no account required.
Does it work on other AI chat platforms?
Yes. CastReader also has dedicated extractors for Claude, Gemini, DeepSeek, Kimi, and Doubao.
How do I listen to ChatGPT responses?
Install the free CastReader Chrome extension. A small 🔊 Listen button will appear next to every ChatGPT response on chatgpt.com. Click it to hear that specific reply read aloud with a natural AI voice.
Does ChatGPT have built-in text-to-speech on the web?
No. As of 2026, chatgpt.com has no read-aloud or TTS feature. Voice features only exist in the ChatGPT mobile apps. CastReader is the only way to listen to ChatGPT responses in your browser.
