Per-Response
One Button Per AI Response
A small 🔊 button appears next to every AI response. Click it to listen to just that response — not the entire conversation. Perfect for long explanations you'd rather hear than read.
Smart Extraction
Reads Content, Not UI
Each platform has a dedicated extractor that understands its DOM structure. Thinking blocks, artifacts, code blocks, and UI elements are filtered out. Only the actual response gets read.
Natural Voices
Auto Language Detection
CastReader detects the response language automatically. Chinese responses use Chinese voices, English uses English voices. 40+ languages supported with Kokoro TTS — natural, not robotic.
Frequently Asked Questions
Everything about listening to AI conversations with CastReader
How do I listen to a ChatGPT response?
Install CastReader, go to chatgpt.com, and you'll see a small 🔊 button next to each AI response. Click it to start listening. The button appears automatically — no setup needed.
Does it read the entire conversation or just one response?
Each response has its own listen button, so you choose exactly which response to hear. You can also use the extension icon to read the full conversation if you prefer.
Does it work with Claude's thinking blocks?
Yes. CastReader's Claude extractor automatically skips thinking blocks and artifacts, reading only the actual response content.
What about code blocks in AI responses?
Code blocks are skipped by default so you hear the explanation, not the code syntax. This makes technical responses much more listenable.
Is it free? Are there usage limits?
CastReader is completely free with no usage limits, no account required, and no API key needed. Listen to as many AI responses as you want.
Does it work on mobile AI apps?
CastReader is a Chrome/Edge browser extension, so it works on the web versions of these AI platforms (chatgpt.com, claude.ai, etc.). Mobile apps have their own built-in voice features.
Can I use it on AI platforms not listed here?
CastReader has a generic detection mode that works on many AI chat interfaces beyond the six officially supported ones. If the platform uses a standard chat layout, the listen button will likely appear.
Does it highlight text while reading?
Yes. As CastReader reads an AI response, each paragraph highlights in real-time so you can follow along visually while listening.
