Once installed as a Chrome or Edge extension, or opened as an iPhone, iPad or Android app, it reads supported pages and documents aloud using natural AI voices while a word-synced highlight and auto-scroll keep your place. A public Voice Hub lets you preview real voice samples by language before committing, and playback speed ranges from standard rates up to 3x on the paid plan. What separates it from a plain screen reader is a feature called Read & Explain. Instead of only pronouncing a dense or foreign-language paragraph, CastReader works out what it means and walks you through it in the language you know best, while an animated pen circles and underlines the relevant lines in the original text. That mix of eyes-on-page and ears-on-explanation is aimed at research papers, technical documentation, foreign-language news and other long reads where passive narration is not enough. Sources are organised into four families: book platforms such as Kindle, WeRead, Google Play Books, Libby, Kobo and O'Reilly; articles and subscriptions including Medium, Substack, The Atlantic, The New Yorker and major newspapers; work documents and email such as Google Docs, Notion, Gmail and Google Drive; and AI conversations from ChatGPT, Claude, Gemini, DeepSeek and Kimi. CastReader also offers private voice cloning for your own documents and a developer Voice API for embedding cloned speech into applications. Free use needs no account, and payments are handled by Stripe. **Pricing & Plans:** Freemium.

The extension listens to your voice, transcribes it into the ChatGPT input box and submits the message automatically; when the answer arrives, it is read aloud. The result feels closer to a spoken conversation than to a chat window. On top of that core loop it adds a handful of workflow features. You can save prompts and insert them with a click, use prompt injection to append extra context to a saved prompt before it is sent, let ChatGPT display related images inline, or pick a text file and push its contents straight into the chat. An auto-prompt mode fires a queue of prompts one after another, waiting for each answer before sending the next, which is handy for batch tasks you would otherwise repeat by hand. It is a small, developer-run project published in 2023 with a deliberately narrow scope. If your main frustration with ChatGPT is the keyboard, this removes it; if you want a full AI productivity suite, look elsewhere. **Pricing & Plans:** The extension is listed as a free Chrome add-on with no subscription tiers shown on its store page. You still need your own access to ChatGPT to use it. - **Voice input that submits itself:** Speak your question and the extension transcribes it into ChatGPT and sends it, no typing or Enter key required. - **Spoken answers:** ChatGPT's response is read back out loud so you can listen while doing something else. - **Saved prompts and prompt injection:** Store reusable prompts and inject extra context into them before they are submitted automatically. - **Auto-prompt queue:** Line up several prompts and let the extension submit them one by one, waiting for each answer before the next. - **Files and images in the chat:** Select a text file to submit directly into ChatGPT and surface related images inline in the conversation. **Strengths:** Fully voice-driven loop: speak in, listen out; Saved prompts plus prompt injection cut repetitive typing; Auto-prompt queue is genuinely useful for batch requests; Small and lightweight with no visible subscription tiers **Limitations:** Only automates the existing ChatGPT web page rather than providing its own chat interface; Speech recognition quality depends on your browser and microphone setup; Very small install base and last update in 2023, so long-term maintenance is uncertain [Profile (Markdown)](https://openaitools.app/tool/chat2gpt.md) ## Frequently Asked Questions ### How do CastReader and Chat2GPT compare in monthly traffic?
