โThis 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.โ
Listen to Kimi Responses
A ๐ Listen button appears next to every Moonshot Kimi response โ including share pages. Click to hear just that answer, no copying, no switching apps.
How CastReader Works with Kimi
Built for Moonshot Kimi's unique DOM structure
One Button Per Kimi Answer
Every Kimi response gets its own ๐ Listen button. Click to hear only that answer โ not the whole conversation. Perfect for Kimi's long-context responses.
Works on Shared Conversations Too
Kimi share pages use a different DOM structure than the main chat. CastReader detects both and injects the Listen button reliably, so you can listen to any shared Kimi conversation just like your own.
Chinese & English, Auto-Detected
Kimi excels at Chinese and English responses. CastReader picks a matching natural voice automatically โ no settings to toggle. Powered by the Kokoro TTS model.

Source โWhat Readers Say โ Including the Critical Reviews
Every Chrome Web Store review below is verifiable at the link in each card. We don't hide negative feedback โ we answer it within 24 hours.
โWorks 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.โ
โExtremely 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.โ
โAt 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.โ
โSo 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.โ
โBest one i found, user friendly, and great voice over.โ
โChatGPT's long answers are finally listenable. Let it generate while I listen โ doubles my productivity. Love the inline button next to each response.โ
โI 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.โ

First wave of extraction reliability improvements
OCR success rate improved from 78% to 89% on English-language Kindle books. Multi-column page detection added for academic PDFs.
Why This Exists
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 โ Amazon's Cloud Reader font encryption โ turned out to be solvable with OCR. The product problem โ making it actually pleasant across phones, desktops, and 40+ languages โ took two years of iteration. We're a small team. I answer every Chrome Web Store review personally (see testimonials above โ including the 3-star and 1-star ones). If something's broken or missing, email support@castreader.ai.
