Por que escolher CastReader em vez de NaturalReader
TTS with immersive reader mode and OpenDyslexic font? Veja o que o CastReader faz de diferente.
On-Page Reading
Highlights on the Actual Page
NaturalReader strips the page and shows text in a separate reader view. You lose images, formatting, and context. CastReader highlights paragraphs directly on the original webpage — the page looks exactly the same, just with the current paragraph lit up.
Kindle & WeRead
Works Where NaturalReader Fails
NaturalReader cannot read Kindle Cloud Reader or WeRead books. CastReader is the only extension that handles both — using OCR for Kindle's encrypted fonts and API interception for WeRead's canvas rendering.
Free Forever
No $99.50 Price Tag
NaturalReader costs $99.50 one-time for its full feature set. CastReader is free — same paragraph highlighting, natural AI voices, and clean extraction, at zero cost. No trial period, no feature gating.
Perguntas frequentes
CastReader vs NaturalReader — perguntas comuns
Is CastReader better than NaturalReader?
For web reading: yes. CastReader highlights on the actual page (NaturalReader uses a separate view), works on Kindle and WeRead (NaturalReader doesn't), and is free (NaturalReader costs $99.50). NaturalReader has a nice OpenDyslexic font option and immersive reader mode that some users prefer.
Does NaturalReader work on Kindle?
No. NaturalReader cannot read Kindle Cloud Reader books because Amazon uses encrypted fonts. CastReader is the only extension that works — it uses OCR to read the rendered page image.
Is CastReader free?
Yes, 100% free. No account, no trial, no limits. NaturalReader has a free tier with limited voices; full access costs $99.50.
Does CastReader have an OpenDyslexic font option?
CastReader doesn't change fonts — it reads the page as-is with paragraph highlighting. For font changes, use a separate extension like Helperbird alongside CastReader. Both work together.
Which is better for dyslexia?
Both help. NaturalReader's immersive reader + OpenDyslexic font is great for clean reading. CastReader's on-page highlighting + natural voices is better for reading in context. For dyslexia support, see our dedicated page at /text-to-speech-for-dyslexia.
