Scribble Hub does not read chapters aloud on its own. CastReader adds that: open a chapter in Chrome or Edge, press play, and keep going through the serial while your eyes rest.
Web serials are long — hundreds of chapters, read over months
No copying text into another app. Open the chapter page as you normally would, click CastReader, and it reads the chapter you are on.
The current paragraph is marked and the page scrolls with it. When you look back at the screen you already know where you are — which matters when a chapter runs 4,000 words.
Progress is remembered, so picking a serial back up after a few days lands you where you stopped rather than at chapter one.
Scribble Hub is free to read. CastReader is free to start and needs no signup. Faster playback speeds and premium voices are CastReader Pro features.
What people ask before installing
No. Scribble Hub has no built-in read-aloud feature — not on the website and not in its app. Listening requires a separate reader such as CastReader, a browser extension, or your browser's own read-aloud mode.
Not by itself. The site displays chapters as ordinary text and leaves reading to you. CastReader reads that text aloud in place, so you stay on the Scribble Hub page instead of pasting chapters somewhere else.
Install CastReader from the Chrome Web Store, open any Scribble Hub chapter, and click the CastReader icon. It reads the chapter text on the page, highlighting each paragraph as it goes.
No — CastReader's browser extension works on the Scribble Hub website in Chrome or Edge. On a phone, open the chapter in the browser rather than the app, or use the CastReader app for iPhone, iPad and Android.
Edge's Read Aloud does work on Scribble Hub, and it is free. It reads the whole page, has a limited voice set and does not remember where you stopped between sessions — which is the part that matters on a serial you read over weeks.
Yes. Playback speed is adjustable from the player. Speeds above 1.25x are a CastReader Pro feature.
Free to start, with no account. CastReader Pro adds premium voices, faster speeds and longer listening.
Yes. It reads ordinary web pages, so Royal Road, AO3, Wattpad and FanFiction.net work the same way.

“This is 1 of the best TTS and its smooth. If this is truly free i'll keep this 100%. Every other TTS says its free but has a secret. They interrupt or they just say better ai voices pay. But i like this voice. I've tried loads and this is 1 of the best ones that actually says free.”
“Works perfectly on vivaldi. One suggestion though. I wish it had a play button appear next to a paragraph when we hover over it. Just like in the case of speechify.”
“Extremely user friendly short keys. Placed forward backward and speed up down as Natural as it could be. Voices are great and smooth. I would recommend it over many hyped products.”
“At the very least it's better than many paid TTS models. Still not as good as ElevenReader or LAP, but maybe the best free model for TTS.”
“So glad I can finally switch voices! The default was fine but I found one I actually enjoy listening to for hours. Small thing, huge difference.”
“Best one i found, user friendly, and great voice over.”
“ChatGPT's long answers are finally listenable. Let it generate while I listen — doubles my productivity. Love the inline button next to each response.”
“I tried using this add-on to listen to an ebook on the O'Reilly learning platform, and it works smoothly. However, it always restarts from the first paragraph whenever I scroll or select a different paragraph. Please consider adding a bookmark or checkpoint feature so users can mark where the reading should begin.”

Ranked #10 in Daily, 99 upvotes, 4 community comments shaped the v1.2 roadmap.
Switched from older TTS engines to Kokoro neural voices. User reviews shifted from 'usable but robotic' to 'enjoy listening for hours' (verbatim from review by patrick chiang).
OCR success rate improved from 78% to 89% on English-language Kindle books. Multi-column page detection added for academic PDFs.
I built CastReader because I owned hundreds of Kindle books and couldn't listen to them on my morning runs without buying separate Audible copies. The technical problem — Amazon's Cloud Reader font encryption — turned out to be solvable with OCR. The product problem — making it actually pleasant across phones, desktops, and 9 supported languages — took two years of iteration. We're a small team. I answer every Chrome Web Store review personally (see testimonials above — including the 3-star and 1-star ones). If something's broken or missing, email support@castreader.com.
