How CastReader Helps You Study
Turn reading assignments into listening sessions
Textbooks
Listen to Kindle Textbooks
Open your textbook on Kindle Cloud Reader (read.amazon.com) and click CastReader. It's the only Chrome extension that works on Kindle — every other TTS extension fails because Amazon encrypts the text. CastReader uses OCR to read what's on screen. Your entire Kindle library becomes listenable.
Research Papers
Listen to Academic Papers
ArXiv, Google Scholar, PubMed, SSRN — CastReader reads papers from any source. It extracts the article content and skips headers, footers, and reference lists. Highlight tracking keeps your place while the paper is read aloud. Great for first-pass reading before deep analysis.
Multitask
Study While Doing Other Things
Listen to assigned readings while walking to class, working out, or doing laundry. CastReader's Send to Phone feature streams audio to your phone via Telegram — start reading on your laptop, continue listening on your phone. Turn dead time into study time.
Better Retention
Hear It and See It
Dual-channel learning — hearing text while seeing it highlighted — improves retention compared to reading alone. CastReader highlights each paragraph as it's read, so you get both visual and auditory input simultaneously. Speed it up for review, slow it down for new material.
Everything Else
Google Docs, PDFs, Wikipedia, AI Chats
Lecture notes in Google Docs. Assigned PDFs. Wikipedia deep dives. ChatGPT explanations. CastReader reads them all with the same one-click experience. No need to copy-paste text into a separate app.
Why Students Use Text to Speech for Studying
The average college student is assigned 200-400 pages of reading per week. That's across 4-5 classes, each with textbooks, journal articles, and supplementary materials. Nobody actually reads all of it. Students skim, skip, and cram — not because they're lazy, but because there aren't enough hours to read everything carefully while also attending lectures, writing papers, and maintaining basic human functions like sleeping.
Text-to-speech changes the math. When you can listen to readings while walking between classes, doing laundry, or commuting, those dead time slots become study time. A 30-minute bus ride turns into a chapter of your sociology textbook. A 20-minute walk becomes an arXiv paper for your ML class. You're not replacing careful reading — you're adding a first-pass that primes your brain for deeper engagement when you do sit down to study.
CastReader is designed for this workflow. It reads any webpage — textbooks on Kindle Cloud Reader, papers on Google Scholar, notes on Google Docs — with paragraph highlighting so you can follow along visually or just listen. Speed control lets you go faster on familiar material and slower on dense passages. It's completely free with no word limits, which matters when you're a student.
The technical challenge is that many academic sources use unusual page structures. Kindle encrypts text with custom fonts. arXiv papers are rendered as static images. Google Docs uses a complex internal editor. CastReader has dedicated extractors for all of these — it understands each platform's specific DOM structure instead of trying to read random text from the page.
Frequently Asked Questions
Common questions about using text to speech for studying
Is CastReader free for students?
Yes, CastReader is 100% free for everyone. No student email required, no verification, no trial period, no word limits. Install from the Chrome Web Store and start using it immediately.
Can CastReader read my Kindle textbooks?
Yes. Open your textbook on Kindle Cloud Reader (read.amazon.com) and click CastReader. It's the only Chrome extension that works on Kindle because it uses OCR to bypass Amazon's encrypted fonts. Every other TTS extension fails on Kindle.
Does listening to textbooks actually help with studying?
Research shows that combining audio with visual text improves comprehension and retention compared to reading alone. TTS is especially effective for first-pass reading — it primes your brain for deeper engagement when you review later. It also lets you study during time you'd otherwise waste (commuting, walking, exercising).
Can I listen on my phone while walking to class?
Yes. CastReader's Send to Phone feature streams audio to your phone via Telegram. Start reading on your laptop, grab your phone, and the audio continues as you walk. It even auto-turns pages for Kindle books.
Does CastReader work with Google Docs and PDFs?
Yes. CastReader has dedicated extractors for Google Docs, PDFs viewed in the browser, Notion, and many other platforms. It reads the document content and skips UI elements. One click, same experience everywhere.
Can CastReader read research papers from arXiv or Google Scholar?
Yes. CastReader reads papers from arXiv, Google Scholar, PubMed, and any academic publisher's website. It extracts the paper content and skips headers, navigation, and reference formatting. Great for getting through reading lists faster.
How fast can CastReader read?
Speed control goes from 0.5x to 3x. Most students use 1.5x-2x for general reading and slow down for technical or unfamiliar material. You can adjust the speed while listening without any interruption.
Is text to speech considered cheating?
No. Text to speech is a reading tool, not a writing tool. It's officially recognized as an accommodation by most universities and standardized testing organizations. Using TTS is no different from listening to an audiobook version of your textbook.
