You read the whole paragraph… and still have no idea what it actually said.
Most read-aloud tools won't help with that — they just narrate the words back, robot-style.
CastReader is different. It doesn't just read the page — it explains it. 🖊️
Dense or jargon-heavy passage (or one in another language)? CastReader breaks it down in plain words, in the language you actually think in — so a hard page finally makes sense.
A long document you'd normally zone out listening to? Its pen highlights the key points as it reads, then distills and explains them — so the important stuff actually lands.
Less zoning out. More actually getting it.
Read it, hear it, finally understand it.

Exciting new feature! Read-along highlighting: grab a virtual pen, highlight key points on the page, and breeze through long articles!
CastReader just got a fresh update. I've been building this product since last year, and after pivoting my strategy a few times, I'm finally seeing some light at the end of the tunnel. Getting a few paid users every single day now, and honestly, I couldn't be happier.
It's a Chrome extension with these core features:
Read-along web reading: Text highlighting with adjustable playback speed.
Smart content summarization: Like having a personal assistant with a highlighter pen, it extracts key takeaways and marks up the page to boost your reading efficiency.
Auto-translation: Translates foreign web pages into your native language and reads them out loud to you.
Versatile support: Read any webpage or local files seamlessly after installation.
This groundbreaking feature was an absolute game-changer for me when I built it. Everyone who’s tried it so far is totally hooked! Give it a spin and let me know what you think—I’d love your feedback!
Hey all — solo maker here, just shipped the feature I'm most excited about.
You know the problem with most TTS tools: they free up your eyes, but your brain still can't keep up. Hit a dense doc or a hardcore explainer and the voice just drones on word for word — by the end your head's mush and you're rereading it yourself anyway. Slow and exhausting.
That's the part I wanted to fix, so CastReader now has a Read & Explain mode. Instead of reading verbatim, it explains as it goes — all in sync with the audio. Three things I'm proud of:
It explains, not just narrates — it breaks down the convoluted bits and says them in plain language, so dense or obscure writing clicks by ear.
It marks up the page as it talks (my favorite part) — a virtual pen moves across the original text in sync with the voice, circling and highlighting the key info, like taking notes by hand. Light touch, never covers the text; your eyes follow the pen, so you stop drifting off mid-listen.
Synced subtitles — every line of explanation shows up word-by-word, so you read and listen at once.
The way I think about it: it's not an AI summary that hands you a detached block of text — it's more like a tutor sitting next to you with a pen, circling things and explaining while you both stay on the same page. You're anchored to the source, not a summary that floats off on its own.
