What do you want CastReader to read?
Copied text, a document, a webpage, a Kindle book, or a difficult passage each needs a different reading surface. Start here and route the content to the CastReader workflow built for it.
Choose the right read-aloud path
The public paste-to-audio demo is currently offline. Choose the supported app, extension, or document workflow below instead of sending content to a tool that cannot complete the job.
Copied text or a short passage
Use the mobile app or a supported CastReader surface to paste text and start a reading session.
PDF, DOCX, EPUB, or image
Use the upload workflow for longer files, OCR, document structure, and document-friendly playback.
Webpage, article, or AI answer
Install the browser extension to read supported rendered pages aloud in place with highlighting.
Kindle books on a phone
Use the iPhone or Android app for a phone-first Kindle bookshelf and long listening sessions.
Google Docs or browser work
Use the browser workflow and troubleshooting guide when ordinary read-aloud controls cannot access the document.
A passage I need to understand
Use Read & Explain to keep the source visible and choose Overview, Standard, or Deep guidance.
Why route reading into a listening workflow?
Choose a supported CastReader surface when audio, highlighting, progress, or explanation makes the material easier to finish.
Multitasking
Listen While You Do Life
You can't read an article while folding laundry, doing the dishes, or driving. But you can listen to one. Turn your reading materials into audio and reclaim your time. It's the ultimate productivity hack for busy people.
Eye Relief
Give Your Eyes a Rest
Screen fatigue is real. If you've been staring at a computer all day, reading another PDF feels like torture. Just switch to 'Read This to Me' mode, close your eyes, and absorb the information without the eyestrain.
Better Proofreading
Catch Typos Your Eyes Miss
When you read your own writing, your brain often auto-corrects mistakes. Hearing it read back to you by a neutral AI voice exposes awkward phrasing and typos instantly. It's the secret weapon of great writers.
Simplicity
Start Simple, Then Use the Right Surface
Use the app or extension designed for the source. Webpages, documents, Kindle books, and Google Docs need different extraction and playback controls.
Common Questions
Straight answers about choosing a CastReader reading workflow
Why is there no working paste-to-audio box on this page?+
The public anonymous web generator is currently offline. This page now routes each content type to a supported CastReader app, extension, or document workflow instead of presenting a control that returns an error.
What can I do for free, and when is Pro needed?+
CastReader is free to start with daily allowances. Pro provides higher usage limits and additional voice and explanation access. See the pricing page for current limits.
Which workflow should I use for copied text?+
Use the download center to choose a mobile or browser surface that accepts the text where you are reading. The public web generator on this page is not currently available.
Can CastReader read PDFs, DOCX files, EPUBs, and images?+
CastReader provides document workflows for PDF, DOCX, EPUB, and image or screenshot OCR. Availability depends on file access, format, DRM, extraction quality, and the selected surface. Start with document upload.
Can CastReader read webpages and Google Docs?+
The browser extension can read supported rendered pages and has dedicated workflows for sources such as Google Docs. Website structure and permissions can change, so no extension can guarantee every page.
Can it listen to Kindle books on iPhone and Android?+
Use the Kindle on Phone workflow for iPhone or Android. Availability depends on the book, platform, content access, and the text CastReader can legitimately process.
Can CastReader explain difficult or foreign-language text?+
Yes, through Read & Explain. It keeps the source visible and provides Overview, Standard, or Deep guidance. It is a reading aid, not certified translation or professional advice.
Does one account sync everything across devices?+
The same login email keeps Pro entitlement aligned across supported surfaces. File libraries, content, and progress availability vary by workflow and should not be assumed to sync universally.
How is my content handled?+
Content may be processed to provide extraction, OCR, speech, account, or explanation features. Do not submit material you are not allowed to process, and review the privacy policy for current handling details.
Which voice should read my book, PDF, or study material?+
Use the reading voice library to filter and preview the real catalog. Choose for sustained clarity over a long session, not only for the first sentence.
