Listen to Perplexity Answers
CastReader reads Perplexity AI answers aloud with natural voices and word-by-word highlighting — automatically skipping the sources list so you hear just the answer.
Rate limiting at scale uses distributed counters, typically with token-bucket or sliding-window algorithms. Counters live in Redis or similar so any instance can enforce limits. The tricky part is agreeing on global state without making every request slow.
Reads the answer, skips the sources list
How CastReader Works with Perplexity
Smart extraction meets natural text-to-speech
New in 2026
🔊 Listen Button on Every Perplexity Answer
CastReader adds a small Listen button next to every Perplexity answer — including Focus mode responses and Pro search results. Click to hear just that answer. Works on perplexity.ai, including shared answer pages.
Smart Extraction
Reads the Answer, Not the Sources List
Perplexity answers come bundled with a long citations panel — source cards, follow-up questions, related searches. CastReader's dedicated extractor identifies just the main answer text and ignores the source list, so you hear the content without the citation noise.
Highlighting
Follow Along Word-by-Word
Each word highlights in real-time as it's read aloud. Auto-scroll keeps you in sync with long Perplexity research answers. Click any paragraph to jump to that point.
Natural Voices
40+ Languages, Natural AI Voices
Powered by the Kokoro TTS model. Not robotic — natural, expressive voices across 40+ languages. Perfect for listening to long Pro search and Deep Research answers while you work.
Frequently Asked Questions
Everything you need to know about listening to Perplexity with CastReader
Can Perplexity read answers out loud?
Perplexity itself has no built-in voice or read-aloud feature for its text answers. CastReader adds a 🔊 Listen button next to every Perplexity answer so you can hear any response read aloud with natural AI voices — completely free.
Where does the Listen button appear on Perplexity?
A small 🔊 Listen button appears next to every Perplexity answer automatically — on the main conversation, shared answer pages, and Pro search results. Click it and only that answer is read aloud. Citation numbers and the sources panel are skipped.
Does it work on perplexity.ai?
Yes. CastReader has a dedicated extractor for perplexity.ai that understands how Perplexity separates the answer text from the sources list, follow-up questions, and related searches. It works on both perplexity.ai/search/ and shared perplexity.ai/answer/ pages.
Does it skip the sources and citation markers?
Yes. Perplexity answers include inline citation markers like [1], [2], [3] and a sources panel below every answer. CastReader strips these automatically so you only hear the actual prose — not a robotic voice reading out 'bracket one, bracket two'.
Does it work with Pro search and Deep Research answers?
Yes. Pro search and Deep Research produce longer, more structured answers, which is exactly when read-aloud is most useful. CastReader handles multi-section answers, streams the audio progressively, and keeps up with auto-scroll so you can listen to a 10-minute report hands-free.
Can I listen to shared Perplexity answers?
Yes. CastReader works on public Perplexity answer links (perplexity.ai/search/...) and shared answer pages you receive from others. No Perplexity login required — if the page is public, CastReader can read it.
Is it free?
Completely free. No API key, no usage limits, no account required. Install the Chrome extension and start listening.
