ChatGPT
Quantum computing uses quantum bits, or qubits, which can exist in multiple states simultaneously. Unlike classical bits that are either 0 or 1, qubits can be both at the same time through a property called superposition. This allows quantum computers to solve certain problems exponentially faster than traditional computers.

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.
