FAQ
Is this audiobook really free?
Yes. "Life Movements in Plants, Volume II" is a public domain work from Project Gutenberg. CastReader converts it to audio using AI text-to-speech for free. No account or payment needed.
What does the AI voice sound like?
CastReader uses Kokoro TTS, a natural-sounding AI voice. It handles punctuation, names, and dialogue naturally. Most listeners forget it's AI after a few minutes.
Can I listen on my phone?
Yes. Open the book, then use "Send to Phone" to stream audio to your phone via Telegram. No app download needed.
