Everything Speechify Does, Without the Price Tag
Side-by-side: what you get for $0 vs $139/year
Free Forever

Frequently Asked Questions
Switching from Speechify to CastReader
Is CastReader really free? What's the catch?
No catch. CastReader uses the open-source Kokoro TTS model. There's no API cost, so there's no reason to charge. Unlimited usage, all features, forever free.
How does voice quality compare to Speechify?
CastReader uses the Kokoro TTS model which produces natural, expressive voices in 40+ languages. Many users find it comparable to Speechify's premium voices. Try it yourself — it's free.
How much does Speechify cost in 2026?
Speechify Premium costs $139/year (billed annually, no monthly option). The free tier limits you to low-quality system voices and basic features. CastReader offers comparable functionality for free with no restrictions.
Is there a free version of Speechify?
Speechify has a free tier, but it's severely limited — robot-sounding system voices, no premium AI narrators, and restricted features. For a fully-featured free alternative, CastReader offers natural AI voices, paragraph highlighting, and unlimited usage with no paywall.
Can Speechify read Kindle books?
No. Speechify cannot read Kindle Cloud Reader because Amazon encrypts the text with custom fonts. CastReader is the only TTS tool that works on Kindle — it uses local OCR to decode the encrypted text. It also supports auto page-turning for continuous listening.
What are the best free apps like Speechify?
CastReader (Chrome extension, fully free, natural voices), Read Aloud (open source, bring your own API key), and your browser's built-in Read Aloud (Edge has excellent neural voices). For desktop files, Balabolka (Windows) is free and handles PDFs and EPUBs.
Does CastReader have a mobile app?
Currently CastReader is a Chrome/Edge browser extension. For mobile listening, use the Send to Phone feature — it pushes audio to your phone via Telegram so you can listen on the go. A native mobile app is on the roadmap.
Does CastReader work with Notion and Google Docs?
Yes. CastReader has dedicated extractors for both Notion and Google Docs. A listen button appears next to your document title — one click to hear the entire document read aloud with word-level highlighting.
How does Speechify compare to NaturalReader?
Speechify ($139/year) has better voices but costs more. NaturalReader ($99.50 one-time) is cheaper long-term with solid voice quality. CastReader is free with comparable voice quality to both — and it works on platforms neither supports, like Kindle Cloud Reader and WeRead.
Can I use CastReader for studying with ADHD?
Yes — many users with ADHD find CastReader helpful. The paragraph highlighting keeps your eyes anchored to the text while you listen, reducing the urge to drift. It works on any study material in your browser: textbooks, articles, documentation, Google Docs notes.
