How CastReader Works with Grok
Built for Grok's real-time, X-integrated answer style
Listen Button on Every Answer
🔊 Next to Every Grok Response
A small Listen button appears next to every Grok reply — on grok.com's main chat, on X.com's inline Grok panel (the one that opens when you tap the Grok icon on a post), and on shared Grok answer pages. Click to hear just that answer.
Real-Time Results Supported
Live Web Results Get Read Cleanly
Grok pulls real-time info from X and the web. When an answer contains live data — news, prices, post references — CastReader announces 'live results' once and then reads the prose naturally, without spelling out every inline citation marker.
Smart Extraction
Reads the Answer, Not the X UI
X.com is busy — timeline, trending panel, post composer, Grok input box. CastReader's Grok extractor identifies just the answer body and ignores everything else. On grok.com the same extractor handles the cleaner chat layout.
Natural Voices
40+ Languages, No Robot Accent
Powered by the Kokoro TTS model. Not the stock system voice — expressive, natural reading in 40+ languages. Perfect for long Grok DeepSearch answers while you commute or work.
Frequently Asked Questions
Everything you need to know about listening to Grok with CastReader
Can Grok read answers out loud?
Grok's web and X.com interfaces have no built-in read-aloud feature for text answers. The Grok iOS/Android apps have voice mode for chatting, but the browser version — where most long answers happen — does not. CastReader adds a 🔊 Listen button next to every Grok response so you can hear any answer read aloud for free.
Does it work on grok.com and X.com?
Yes, both. CastReader supports grok.com's standalone chat, X.com's inline Grok panel (accessible from the Grok icon), and public Grok share links. The same extraction logic handles all three UIs.
Does it work with Grok's DeepSearch and Think modes?
Yes. DeepSearch produces longer, multi-section answers with citations, which is exactly where read-aloud helps most. CastReader reads the final answer prose and skips inline citation markers like [1], [2]. Think mode reasoning is treated like any other assistant output.
Is the voice different from Grok's own Voice Mode?
Yes. Grok's Voice Mode (in the iOS/Android apps) is for conversing with Grok — you talk, Grok talks back. CastReader is different: it reads existing text answers aloud in your browser, with paragraph highlighting so you can follow along visually. You don't need to re-type anything into voice chat to hear a written answer.
Does it work with Grok 3 / Grok 4 / specialized model picks?
Yes. CastReader reads the rendered page, so it works with every Grok model version — including Grok 3, Grok 4 beta, and specialized modes (Code, Reasoning). New model releases don't require an extension update.
Can I share a Grok answer and have it read aloud to someone else?
Yes. Public Grok answer links (shared from the Share button on an answer) work with CastReader the same way. Recipients just need CastReader installed — no Grok or X login required on their side if the share link is public.
