The AI reader that helps busy people actually finish more books
Ask for a plain-language explanation of dense or confusing passages without leaving the book you are reading.
Bring your own library — ebooks, PDF documents and web articles are all supported formats.
Instant translations, pronunciations and definitions in more than 118 languages turn real books into study material.
The app learns when you are most likely to read and prompts you at that time instead of on a fixed schedule.
Turn scripts into studio-quality AI avatar videos in minutes
Choose from 500+ stock presenters, use photo avatars, or train a custom Video Avatar that looks and sounds like you, then generate narrated videos straight from a script.

An agentic workflow expands ideas into finished videos, with access to leading generative models for video and image generation on higher plans.
