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. Free plan: $0 forever with 20 minutes of listening per day, standard voices up to 1.25x speed, 3 AI explains per day, and 30,000 translation characters per day when signed in.

Your speech is converted into text and dropped into the prompt box, and the assistant's answers can be converted back into speech so you can listen rather than read. For long sessions this makes the tool feel closer to a spoken conversation than a text form. The extension also goes beyond plain transcription. It suggests better-phrased versions of what you said, can draft conversational scripts with GPT, and is designed to keep dialogue focused and natural. Both the speaking rate and the voice used for playback are adjustable, which is useful for learners at different proficiency levels, for people who process audio better than text, and for anyone who wants to practise speaking in a target language. Talk GPT is a free extension published by an individual developer on the Chrome Web Store. It is a third-party product, not an official OpenAI tool, and it works alongside the GPT web interface rather than replacing it. Because it has a small user base and infrequent release cadence, treat it as a handy convenience layer rather than a mission-critical workflow component. **Pricing & Plans:** Free. The Chrome Web Store listing shows no paid tiers or in-app purchases; usage of the underlying GPT service may require your own account. - **Speech-to-text prompts:** Dictate your questions and instructions instead of typing them, and have the transcript placed into the GPT prompt box. - **Text-to-speech replies:** Listen to GPT's responses read aloud, with adjustable speaking speed and selectable voices for different proficiency levels. - **Phrasing suggestions:** Get better-phrased alternatives for what you said, so rough spoken input becomes a cleaner prompt. - **Conversational script drafting:** Use GPT to build scripts and dialogue flows for practice sessions, interviews, or presentations. - **Focus and naturalness tuning:** Keeps exchanges on topic and conversational rather than drifting into long, hard-to-follow answers. - **Free browser install:** Ships as a small Chrome extension (about 200 KB) with a straightforward add-to-Chrome installation. **Strengths:** Free to install and use, with no subscription shown on the listing; Combines dictation, spoken replies, and phrasing help in one small extension; Adjustable voice and speed make it practical for language practice; Minimal footprint (around 200 KB) and no data-selling disclosures from the developer **Limitations:** Small user base and a 2024 last update, so long-term maintenance is uncertain; Independent third-party extension with no official OpenAI affiliation or support; Depends on a separate GPT web session, so results track that service's availability and limits [Profile (Markdown)](https://openaitools.app/tool/talk-gpt.md) ## Frequently Asked Questions ### How do CastReader and Talk GPT compare in monthly traffic?
